In an unprecedented move, the U.S. Food & Drug Administration (FDA) has issued warning letters today to companies selling products containing delta-8 THC. In total, the FDA sent out five warning letters to companies for violating the Federal Food, Drug, and Cosmetic Act (FD&C Act).

The violations include illegal marketing of unapproved delta-8 THC products as treatment for medical conditions, misbranding and adding delta-8 THC to food products. Back in September of last year, the FDA published a consumer update on their website, seeking to educate the public and offer a public health warning on delta-8 tetrahydrocannabinol, otherwise known as delta-8 THC.
Delta-8 THC is a cannabinoid that can be synthesized from cannabidiol (CBD) derived from hemp. It is an isomer of delta-9 THC, the more commonly known psychoactive cannabinoid found in cannabis. Delta-8 THC does produce psychoactive effects, though not quite as much as its better-known cousin, delta-9 THC. Many regulators and industry stakeholders are increasingly concerned about the rise in popularity of delta-8 products, namely because of the processing involved to produce it. Delta-8 THC is often synthesized using potentially harmful chemicals.
The FDA has a history of sending a lot of warning letters to companies marketing CBD products inaccurately and making drug claims. Earlier this year, they sent a number of letters to companies claiming that CBD can cure or prevent Covid-19.
According to Janet Woodcock, M.D., principal deputy commissioner at the FDA, they are getting more and more concerned about the popularity of delta-8 THC products sold online. “These products often include claims that they treat or alleviate the side effects related to a wide variety of diseases or medical disorders, such as cancer, multiple sclerosis, chronic pain, nausea and anxiety,” says Woodcock. “It is extremely troubling that some of the food products are packaged and labeled in ways that may appeal to children. We will continue to safeguard Americans’ health and safety by monitoring the marketplace and taking action when companies illegally sell products that pose a risk to public health.”
The FDA sent warning letters to the following companies selling delta-8 THC products:
Some consumers participating in the legal cannabis market want to avoid inhalable products. They are concerned about the effects of the smoke or they want their usage to be discreet — without the pungent aroma emanating from burning cannabis flower. For those consumers, edibles are the preferred option and a growing product category.
Within the edibles space, the beverage segment — with limited product options in some states — may offer significant potential for growth. In 2021, cannabis-infused beverages accounted for only 1% of total legal cannabis product sales and about 5% of the edibles segment in the United States, reports market researcher BDSA. But cannabis beverage sales are growing around the U.S.
In California, cannabis drinks grew their market share in the edibles category from 4% in 2018 to 7% in 2021. Nevada saw beverages increase their share of edibles revenues from 7% to 10% in the same time frame. And cannabis beverages’ share of edibles sales in Massachusetts went from less than 1% in 2019 to 8% in 2021.
Pegged at $180 million in revenue last year, the cannabis beverage market is projected to reach nearly $500 million by 2026, predicts BDSA.
Today, gummies and chocolate products dominate the edibles category. Although beverages are currently a small segment of edible sales, they may have some inherent advantages — familiarity, faster-acting products from improved bioavailability, and taste and flavor innovations — over other cannabis products. Since beverages can incorporate many different flavors from fruity, cola and sweet to coffee, tea, sour and bitter, these myriad flavor variations can mask or minimize any off-tastes associated with THC.
Viewed as part of their everyday regimen, consumers drink beverages for hydration, nourishment, refreshment and enjoyment. Cannabis beverages are well-suited for consumers’ lifestyles, while gummies and chocolates may be perceived as sugary treats and special occasion items.

Brand owners are beginning to recognize the limited availability of products and growth potential of cannabis-infused beverages and are looking to enter the category. Packaging plays a key role in cannabis beverages, with sustainability, regulatory compliance (e.g., child-resistant), labeling compliance (e.g., warning symbols and text), convenience and branding all contributing to the success of the expanding product category.
Sustainable Packaging
Consumers, especially younger generations, are concerned about the environment and support brands that align with their values. According to the 2020 Sustainable Market Share Index from the NYU Stern Center for Sustainable Business, sustainability-marketed products delivered about 55% of the market growth in consumer packaged goods (CPG) from 2015 to 2019 in the U.S. despite being only 16% of the market. Sustainability-marketed goods grew seven times faster than products not marketed as sustainable and nearly four times faster than the overall CPG market.
As a primary consumer touchpoint, packaging is a good way for cannabis beverage brands to show their commitment to the environment. But finding the most sustainable packaging option for a particular application may not always be as straightforward as it seems. Many considerations are involved — material choice (e.g., plastic, glass, or aluminum), recyclability of the material, the weight of the material, recycled content of the final package, package design (minimalist vs. excessive), transportation costs and other factors like reusability.
To help facilitate the process, Berlin Packaging uses life cycle analysis to determine a product’s environmental impact or carbon footprint over its entire life cycle, including sourcing & raw materials extraction (minerals resource use), manufacturing (energy and water usage), distribution (freight miles, fuel usage) and end-of-life (recovery, recycling, reprocessing).
We have the know-how to improve the sustainability of any packaging material — whether it be lightweighting, use of post-consumer recycled (PCR) content, greater recycling rates and more.
Regulatory Compliance
Because legal cannabis products are regulated by individual states and not at the federal or national level, the regulations for cannabis packaging requirements can vary widely from one state to another. However, there are some common rules that all states follow.
Child-resistant capable cap fits snugly over the top of a can.
All cannabis products — including beverages — require child-resistant packaging to meet the standards of the Consumer Product Safety Commission. For aluminum cans, Berlin Packaging offers a child-resistant capable mechanism that fits snugly over the top of a can. Available in polypropylene or a bio-based resin, the single-use device can be custom developed to fit the exact specifications of the customer’s cans. In-stock products are available for standard 202 can ends.
Along with child-resistant capable packaging, states also require some type of warning symbol and statement on the label to indicate the product contains cannabis. Depending on the state, the symbol may be a triangular or diamond shaped in a bright or contrasting color to call attention to it on the label. The symbol typically houses a cannabis leaf image or “THC”.
Convenience
Like any packaged drink, cannabis beverages need to check all the boxes for consumer convenience — easy to drink, portability, cupholder friendly and resealable.
Users can easily reseal PET and glass bottles with continuous thread or lug finish closures, but cans present a challenge. Berlin Packaging offers a solution with a resealable can that opens like a traditional stay-on-tab. Here’s how it works. Lifting the pull tab breaks the tamper-evident band and unlocks the slider mechanism. Pulling the slider opens the can and makes the familiar venting sound — even after reopening.
The configuration of the opening creates a smooth laminar flow to improve the drinking experience. Moving the slider back to its original position and pushing down the pull tab, which produces a clicking sound, reseal the closure. The tamper-evident band remains on the can underneath the pull tab.
Branding
Cannabis beverages come in drops, shots, syrups, carbonated, iced tea, lemonade, fruity, water, sports & energy, mocktails, tea, coffee and hot cocoa.
Because cannabis has been associated with medicinal uses, many consumers use cannabis products to manage their wellbeing and health. Thus, some cannabis products have been positioned to relieve stress, promote relaxation and sleep, reduce pain and inflammation, improve mental focus, enhance mood or simply for indulgence and enjoyment.
Product positioning and the experience the brand owner wants to create for the consumer can help inform the brand design, personality, and narrative or storytelling. It’s also important that the brand design and messaging resonate with the product’s target audience.
Studio One Eleven, Berlin Packaging’s in-house innovation division, can help cannabis beverage marketers with their product branding from concept to commercialization. We offer market research and consumer insights, brand strategy and visual branding design, brand name development, structural package design, and more. Our services are available at no additional charge in exchange for a customer’s packaging business.

The team at Studio One Eleven helped Cruise Beverage and its B Happy brand tell their story of free-spirited enjoyment with updated branding, expressive flavor names (i.e., Loosen Up Lemon, Peaceful Pear, Mellow Mango, and Blissful Blood Orange), and unique packaging graphics.
Uplifting illustrations speak to the brand’s sense of freedom and relaxation, and the hand-drawn style reflects the craftsmanship of the CBD beverage product. A white background with flavorful pops of color says clean and fresh, while tiny bubble imagery communicates the delightful effervescence of the fizzy drinks.
The adult beverage industry, like any other category of consumer branded products, is driven by trends. If you’re old enough to remember Bartles & Jaymes wine coolers, you probably also remember Zima and Smirnoff Ice, and more recently “healthy” options like Skinny Girl and Michelob Ultra. The sensation that was craft beer saw many brands being acquired by Big Alcohol so that while the brands remain, ownership and production have changed significantly. Gin, tequila and vodka have had their moments in the sun and the current market is undeniably saturated with what is probably the largest current trend – hard seltzers. However, with the seltzer craze waning, many are wondering what’s next. And with the growing sober/California sober trends, some are betting it is cannabis-infused beverages.
Cannabis-infused beverages offer both an alternative method of consumption of cannabis and are also an attractive alternative to alcohol. Infused beverages are more appealing to the new demographic of casually curious cannabis consumers. i.e., consumers that may not be interested in smoking a joint or vaping, but are comfortable micro-dosing from a can or bottle, as they would a seltzer or beer. The same type of consumer may be moving away from alcohol consumption to eliminate hangovers or other negative health effects.
The emerging market and curious consumer group present an enormous opportunity right now for cannabis-infused beverage brands. Of course, with opportunity and growth come challenges. And while cannabis-infused beverages face a host of legal and regulatory challenges relative to sourcing, manufacturing, packaging, labeling, shipping, marketing, distribution and sale, one of the most critically important business assets to address at inception is the brand.
Lines are Blurring, Gaps are Being Bridged
The U.S. cannabis market is currently a geographic hamburger. Hear me out: Geographically, you have a relatively mature market out west and a relatively new and growing market along the east coast. These are the buns. You have a mixed bag in between, with some states coming online and allowing medical or adult use cannabis use and others that have not yet embraced any form of legalization. The landscape has lent itself to the development of regional brands, such that brands that are so similar they might otherwise confuse consumers, have been able to co-exist in different regions without issue, or because there is little to no trade channel or market overlap. Similarly, adult beverages and cannabis have historically been separate verticals, with an arguably low likelihood that a consumer would assume a particular cannabis product and adult beverage product emanate from the same source.

However, lines are blurring and gaps are being bridged. Walls are breaking down. The increasing number of states coming online with legalized cannabis, and the proliferation of multi-state operators (MSOs), means that cannabis brands can grow to be more than siloed regional brands. This will inevitably lead to brands that previously co-existed bumping into one another and there’s bound to be some pushing and shoving. The advent of infused beverages likewise bridges the gap between cannabis products and alcoholic beverages. While the respective industries were not historically per se related, competing, or overlapping, now you’ve got infused beverages that bridge the gap between the two, and traditional alcohol brands (e.g., Boston Beer Company, Molson Coors, Lagunitas, Pabst.) entering the market (albeit under different brands). This makes a strong argument that cannabis and alcohol (or, more generally, adult beverages) are within each other’s logical zones of expansion, for purposes of a likelihood of confusion analysis.
The growing pains infused beverage brands will experience are analogous to those craft beers saw in the 2000 – 2010s. Many craft brewers had catchy, cheeky names and brands that contributed to their ability to engage consumers and develop a following, but failure to clear and protect the brands prior to launch detracted from the brands’ market values. Localized use prior to expansion also led to many brands bumping into one another and stepping on each other’s trademark toes. This was significant as the brands sought investment dollars or an exit strategy, making clear that the brand itself contributed heavily to valuation.
Mitigating Risks and Overcoming Challenges: Search and Protect
The risks and challenges can be significantly mitigated and/or overcome with proper preliminary clearance searching and assessments, and by seeking and obtaining state or federal protection for the brand or brands, to the extent possible.
Quatreau CBD infused sparkling water
Of course, clearance searches and assessments come with their own challenges, as does federal protection. With respect to clearance searches, these typically look at U.S. federal and state trademark databases. These resources are not sufficient for purposes of clearing a proposed cannabis brand. Many brands are not recorded at the federal or state level and indeed may not even show up in a basic search engine. An appropriate search looks at social media resources like Instagram, Twitter, Facebook and known cannabis resources like Leafly and Weedmaps. Additionally, the scope of the search should exceed cannabis products and services and at least look at alcohol and merchandise. Adoption and use of a brand for a cannabis-infused beverage is high risk if that brand is similar to a prior existing alcohol brand. A current example is Cointreau’s taking aim at Canopy’s adoption and use of QUATREAU for an infused beverage.
A U.S. federal trademark registration presents its own unique challenges, but is incredibly valuable and beneficial to a brand since it provides the owner with a nationwide presumption of ownership and validity in a trademark, and can also secure priority for the owner with a constructive first use in commerce date that is years before actual use of a mark begins. The U.S. Trademark Office categorically denies protection of brands that violate its “lawful use” rule, and will treat as per se unlawful any applied for mark that covers marijuana, or that covers foods, beverages or pharmaceuticals that contain CBD. With respect to brands that cover products containing THC, since it is federally scheduled, use of the brand would violate the Controlled Substances Act (CSA). With respect to brands that cover CBD or products containing CBD, these may be lawful pursuant to the Farm Bill and the U.S. Trademark Office’s subsequent allowance of marks that claim CBD “solely derived from hemp with a delta-9 tetrahydrocannabinol (THC) concentration of not more than 0.3 percent on a dry weight basis,” however under the Food Drug Cosmetics Act (FDCA) it is currently federally unlawful to introduce CBD – even if it fits the definition above – into foods or beverages.
Even if cannabis is not specifically claimed in a trademark application, cannabis brands have a natural gravitation toward names and logos that can do some of their marketing for them, and announce to the world they cover cannabis. This increases the chances that a trademark application for the brand will get push-back from the U.S. Trademark Office, and if not at the initial review stage, then at the point in time when the brand must submit to the U.S. Trademark Office a sample of (lawful) use of the applied-for mark. While this all sounds like bad news for cannabis-infused beverages, all is not lost.
There are typically ancillary and federally lawful products and services cannabis companies offer under their brands that can be covered in a U.S. federal trademark application, and arguments to be made that registered protection of a brand for the ancillary items should be sufficient to enforce against third parties using the same or confusingly similar brands in their space. Some cannabis brands’ lawful ancillary products are actually product lines (e.g., beverages) offered under the same brand that contain no cannabis. Others may be more causally related, like online forums and blogs. The former is closer to the actual product, and the latter would be more beneficial to a brand that is inherently stronger and more distinctive. One note of caution: A trademark application and eventual registration that expressly disclaim cannabis (THC or CBD) may be difficult to enforce against a third party using the same or a similar mark on and in connection with cannabis. So, while there is a natural inclination to follow a U.S. Trademark Office request to disclaim coverage of cannabis, there may be enforcement consequences down the road.
The cannabis-infused beverage market is poised for explosive growth. The brands that survive – and succeed – will be those that position themselves for growth by clearing and buttoning up their brands as early as possible. The market leaders will be those that select strong and distinctive brands, with geographic and market space around them for growth and expansion; and those that protect and enforce their brands, to the extent possible, at the federal and/or state levels.
Once again, the U.S. Food and Drug Administration (FDA) has issued a number of warning letters to companies selling hemp-derived cannabidiol (CBD) products. This time around, the FDA sent these warning letters to companies that had statements on their website claiming CBD is an effective treatment or prevention of Covid-19.
In this latest round, the FDA sent a total of seven warning letters to:
Just some of the many hemp-derived CBD products on the market today
Earlier this year, a slew of preliminary research studies went viral for shedding light on promising signs that certain cannabis compounds could help treat or prevent Covid-19. The conclusions from most of that research is: It is still too early to tell if any of these studies will show evidence of cannabis treating Covid-19, let alone if they mean cannabis products can be used as a treatment or preventative for Covid-19. However, the research is significant and we should keep an eye on any developments that come from those studies.
The hemp-derived CBD market has a history of clashes with the FDA over health claims. Since the Farm Bill legalized cannabis with less than 0.3% THC back in 2018, the hemp-derived CBD market has proliferated, with all sorts of companies seizing the opportunity. Jumping on the health and wellness trend, companies incorporated this messaging into their marketing campaigns. Over the past four years, the FDA has issued dozens and dozens of warning letters and threatened enforcement actions to companies making unsubstantiated health claims about CBD.
While CBD definitely does have medical benefits, such as being used as an anti-inflammatory or anticonvulsant, preliminary research alone is not enough to say it does. Products need to be approved by the FDA with a new drug application (NDA) in order to make those claims. Therefore when companies make unsubstantiated health claims about their CBD products, like claiming it can prevent Covid-19, they are violating the FD&C Act by marketing “unapproved new drugs” or “misbranded drugs.”
The bottom line is companies that are marketing CBD products need to ensure that their marketing materials and labeling comply with FDA requirements and avoid making unapproved drug claims.

Sample preparation is an essential part of method development and is critical to successful analytical determinations. With cannabis and cannabis products, the analyst is faced with a very challenging matrix and targets that may range from trace level through percent level thus placing considerable demands on the sample preparation techniques.1 The optimal sample preparation, or “extraction”, method for potency analysis of cannabis flower was determined using a methanol extraction coupled with filtration using regenerated cellulose filters.
In the United States (US), Canada, and other countries where medicinal and/or adult recreational cannabis has been legalized, regulatory entities require a panel of chemical tests to ensure quality and safety of the products prior to retail sales2. Cannabis testing can be divided into two different categories: Quality and Safety. Quality testing, which includes potency analysis (also known as cannabinoid testing or cannabinoid content), is performed to analyze the product in accordance with the producer/grower expectations and government regulations. Safety testing is conducted under regulatory guidelines to ensure that consumers are not exposed to toxicants such as pesticides, mycotoxins, heavy metals, residual solvents and microbial contaminates.
Potency testing evaluates the total amount of cannabinoid content, specifically focusing on tetrahydrocannabinol (THC) and cannabidiol (CBD). In the US, the biggest push for accurate total THC is to differentiate between hemp (legally grown for industrial or medicinal use), which is defined as cannabis sativa with a THC limit ≤ 0.3 %, and cannabis (Cannabis spp.), which is any cannabis plant with THC measured above 0.3 %3. Potency testing is typically performed by liquid chromatography (LC) with UV detection to determine the quantity of major cannabinoids.
In addition to reporting THC and CBD, their respective precursors are also important for reporting total potency. Tetrahydrocannabinolic acid (THCA) is the inactive precursor to THC while cannabidiolic acid (CBDA) is the precursor to CBD.4,5
Methods and Materials
Sample Preparation
All samples were homogenized using an immersion blender with a dry material grinder. The nominal sample amounts were 200 mg of flower, 500 mg of edibles, and 250 mg of candy samples.
Potency Extraction Method (1)
Twenty milliliters (mL) of methanol (MeOH) was added to each sample. The samples were mechanically shaken for 10 minutes and centrifuged for 5 minutes.
Potency Extraction Method (2)
Ten mL of water was added to each sample. The samples were mechanically shaken for 10 minutes. 20 mL of acetonitrile (ACN) was then added to each sample and vortexed. An EN QuEChERS extraction salt packet was added to the sample. The samples were placed on a mechanical shaker for 2 minutes and then centrifuged for 5 minutes.
Each extract was split and evaluated with two filtration/cleanup steps: (1) a regenerated cellulose (RC) syringe filter (Agilent Technologies, 4 mm, 0.45 µm); (2) a PFTE syringe filter (Agilent Technologies, 4 mm, 0.45 µm). The final filtered extracts were injected into the ultra-performance liquid chromatograph coupled with a photodiode array detector (UPLC-PDA) for analysis.
Figure 1: Calibration curve for THC potency
Calibration
Standards were obtained for the following cannabinoids at a concentration of 1 mg/mL: cannabidivarin (CBDV), tetrahydrocannabivarin (THCV), cannabidiol (CBD), cannabigerol (CBG), cannabidiolic acid (CBDA), cannabigerolic acid (CBGA), cannabinol (CBN), tetrahydrocannabinol (9-THC), cannabichromene (CBC), tetrahydrocannabinol acid (THCA). Equal volumes of each standard were mixed with MeOH to make a standard stock solution of 10 ug/mL. Serial dilutions were made from the stock to make concentrations of 5, 1, and 0.5 ug/mL for the calibration curve (Figure 1).
Instrumental Method
All instrument parameters were followed from Agilent Application Note 5991-9285EN.8 A UPLC with a PDA (Waters Corp, Milford, MA) detector was employed for potency analysis. An InfinityLab Poroshell 120 EC-C18, 3.0 x 50 mm, 2.7 um column (Agilent Technologies, Wilmington, DE) was utilized for compound separation. The organic mobile phase composition was 0.05 % (v/v) formic acid in HPLC grade MeOH and the aqueous mobile phase composition was 0.1 % (v/v) formic acid in HPLC grade water. The mobile phase gradient is shown in Table 1. The flow rate was 1 mL/min (9.5 minute total program), injection volume was 5 uL, and column temperature was 50 °C.
Table 1: LC mobile phase gradient for potency samples6
Discussion and Results
Table 2 summarizes the relative standard deviations (% RSD) were found for the THC calibrator (at 1 ug/mL) and one extract of a homogeneous sample (utilizing 7 replicates).
Table 2- %RSD values for the instrument response precision for THC in both the calibrations and the homogeneous extract.
The cannabinoid potency of various cannabis plant and cannabis product samples were determined for the various extraction techniques In the chromatograms THC was observed ~8.08 minutes and CBD was observed ~4.61 minutes (Figure 2).
Figure 2: Chromatogram of the 10ug/mL calibrator for potency/cannabinoid analysis
Total potency for THC & CBD were calculated for each sample using the equations below. Equation 1 was used because it accounts for the presence of THCA as well as the specific weight difference between THC and THCA (since THCA will eventually convert to THC, this needs to be accounted for in the calculations).
Table 3 shows the % THC and the total THC potency values calculated for the same flower samples that went through all four various potency sample preparation techniques as described earlier. Figure 3 also provides LC chromatograms for flower sample 03281913A-2 and edible sample 03281912-1.

The results indicated that with the “Potency Extraction Method 2” (ACN/QuEChERS extraction) coupled with the RC filter provided a bias of 7.29 % greater for total THC % over the other extraction techniques. Since the other 3 techniques provided total THC values within 2% of each other, the total THC of the sample is more likely ~14%.
Since the sample dilution for the above data set reduced the CBD content, an undiluted sample was run and analyzed. This data is reported in Table 4.
Table 4- CBD and Total CBD potency values for the same cannabis flower sample processed through different sample preparation techniques.
The CBD results indicated that with the “Potency Extraction Method 1” (methanol extraction) coupled with RC filter, allowed for a greater CBD recovery. This may indicate the loss of CBD with an ACN/QuEChERS extraction.
With an average ~14% total THC and 0.06% total CBD for a homogenous cannabis flower sample, the optimal sample preparation extraction was determined to be a methanol extraction coupled with filtration using a regenerated cellulose filter. Since potency continues to remain at the forefront of cannabis regulatory testing it is important to utilize the right sample prep for your cannabis samples.

As the demand for legal cannabis continues to rise and more states come online, it is imperative to enact more rigorous and comprehensive testing solutions to protect the health of consumers. People use cannabis products for wellness and to find relief; they should not be susceptible to consuming pathogens and falling ill. Especially for immunocompromised consumers, the consequences of consuming contaminated cannabis or hemp are dire. Of course, there should be federal standards for pathogen testing requirements like we have for the food industry. But right now, as cannabis is not yet federally legal, testing regulations vary between states and in many states, testing requirements are too loose and enforcement is minimal. It is up to state legislators, regulators and cannabis operators to protect the health of consumers through implementing more stringent testing.
From the outset, the environmental elements needed to grow cannabis – heat, light, humidity, soil – make cannabis ripe for pathogens to proliferate. Even when growers follow strict sanitation procedures through the supply chain from seed to sale, contaminations can still occur. Cannabis companies need to be hypervigilant and proactive about testing, not just reactive. The lack of regulations in some states is alarming, and as the cannabis industry is highly competitive and so many companies have emerged in a short time, there are unfortunately unscrupulous actors that have skated by in a loose regulatory landscape, just in the game to make a quick buck, even at the expense of consumer health. And there are notable instances where states do not have enforcement in place to deter harmful manufacturing practices. For instance, there are some states that don’t mandate moisture control and there have been incidents of companies watering down flower so it has more weight and thus can be sold at a higher cost – all the while that added moisture leads to mold, harming the consumer. This vicious circle driven by selfish human behavior needs to be broken by stricter regulations and enforcement.
While in the short term, looser testing regulations may save companies some money, in the long run these regulatory environments carry significant economic repercussions and damage the industry at large, most importantly injury or death to customers and patients. Recalls can tarnish a company’s brand and reputation and cause sales and stock prices to tank, and since cannabis legalization is such a hotly contested issue, the media gloms onto these recalls, which opponents to legalization then leverage to justify their stance. In order to win the hearts and minds of opponents and bring about federal legalization sooner, we need safer products so cannabis won’t be cast in such a dangerous, risky light.
Certainly, there’s a bit of irony at play here – the lack of federal regulations heightens the risk of contaminated cannabis reaching consumers, and on the flip side recalls are used by opponents to justify stigmatizing the plant and keeping it illegal. Nevertheless, someday in the not-too-distant future, cannabis will be legalized at the federal level. And when that day happens, federal agents will aggressively test and regulate cannabis; they’ll swab every area in facilities and demand thorough records of testing up and down the supply chain; current good manufacturing practices (cGMP) will be mandated. No longer will violations result just in a slap on the wrist – businesses will be shut down. To avoid a massive shock to the system, it makes sense for cannabis companies to pivot and adopt rigorous and wide-sweeping testing procedures today. Wait for federal legalization, and you’ll sink.
Frankly, the current landscape of cannabis regulation is scary and the consequences are largely yet to be seen. Just a few months ago, a Michigan state judge reversed part of a recall issued by the state’s Marijuana Regulatory Agency (MRA) on cannabis that exceeded legal limits of yeast, mold and aspergillus, bringing contaminated cannabis back to shelves without even slapping a warning label on the packaging to inform consumers of the potential contamination. This is a classic case of the power of the dollar prevailing over consumer safety and health. Even in well-established markets, the lack of regulations is jarring. For example, before this year in Colorado, testing for aspergillus wasn’t even required. (Aspergillus inhalation, which can cause Aspergillosis, can be deadly, especially for people who are immunocompromised). Many states still allow trace amounts of aspergillus and other pathogens to be present in cannabis samples. While traces may seem inconsequential in the short term, what will happen to frequent consumers who have been pinging their lungs with traces of pathogens for 30 years? Consistently inhaling trace amounts of pathogens can lead to lung issues and pulmonary disease down the road. Look what happened to people with breathing and lung issues during the last two years with COVID. What’s going to happen to these people when the next pandemic hits?
We need state regulators and MSOs to step up and implement more aggressive testing procedures. These regulators and companies can create a sea of change in the industry to better protect the health and well-being of consumers. Just complying with loose regulations isn’t good enough. We need to bring shortcomings around testing into the limelight and demand better and more efficient regulatory frameworks. And we should adopt the same standards for medical and adult use markets. Right now, several states follow cGMP for medical but not adult use – that’s ridiculous. Potentially harming consumers goes against what activists seeking legalization have been fighting for. Cannabis, untainted, provides therapeutic and clinical value not just to medical patients but to all consumers; cannabis companies should promote consumer health through their products, not jeopardize it.
For best practices, companies should conduct tests at every step in the supply chain, not just test end products. And testing solutions should be comprehensive. Most of the common tests used today are based on petri dishes, an archaic and inefficient technology dating back over a century, which require a separate dish to test for each pathogen of interest. If you’re waiting three to five days to see testing results against fifteen pathogens and a pathogen happens to be present, by the time you see results, the pathogen could have spread and destroyed half of your crops. So, not only do petri dishes overburden state-run labs, but due to their inherent inefficiencies, relying on these tests can significantly eat into cannabis companies’ revenues. At PathogenDx, we’ve created multiplexing solutions that can identify and detect up to 50 pathogens in a single test and yield accurate results in six hours. To save cannabis companies money in the long run and to make sure pathogens don’t slip through the cracks, more multiplexing tests like the ones we’ve created should be implemented in state labs.
Right now, while the regulatory landscape is falling short in terms of protecting consumer health, better solutions already exist. I urge state regulators and cannabis companies to take testing very seriously, be proactive and invest in creating better testing infrastructure today. Together, we can protect the health of consumers and create a stronger, more trustworthy and prosperous cannabis industry.

As an emerging field in cannabis, contaminant testing remains a gray area for many businesses. The vast differences in state-by-state regulations, along with the frequent changes of previously established rules make testing a difficult, time-consuming process. But at its core, the science and reasoning behind why we test cannabis is very clear – consumer safety and quality assurance are key factors in any legal, consumer market. The implications of federal legalization make cannabis testing even more important to the future of the cannabis supply chain. Understanding the types of contaminants, their sources and how to prevent them is essential to avoiding failures, recalls and risking consumer safety.
When talking about cannabis contaminant testing there are four groups of contaminants: pesticides, heavy metals, foreign materials and microbes. The microbes found on cannabis include plant pathogens, post-harvest spoiling microbes, allergens, toxin release and human pathogens. While all of these can be lurking on the surface of cannabis, the specific types that are tested for in each state vary widely. Understanding the full scope of contaminants and looking beyond state-specific compliance requirements, cultivators will be able to prevent these detrimental risks and prepare their business for the future.
Environmental controls are essential to monitor and regulate temperature and humidity
Beyond just the health of the plant, both medical patients and adult use consumers can be adversely affected by microbial contaminants. To immunocompromised patients, Aspergillus can be life-threatening and both adult use and medical consumers are susceptible to allergic reactions to moldy flower. But Aspergillus is just one of the many contaminants that are invisible to the human eye and can live on the plant’s surface. Several states have intensive testing regulations when it comes to the full breadth of possible harmful contaminants. Nevada, for example, has strict microbial testing requirements and, in addition to Aspergillus, the state tests for Salmonella, STEC, Enterobacteriaceae, coliforms and total yeast and mold. Over 15 states test for total yeast and mold and the thresholds vary from allowing less than 100,000 colony forming units to allowing less than 1,000 colony forming units. These microbes are not uncommon appearances on cannabis – in fact, they are ever-present – so understanding them as a whole, beyond regulatory standards is a certain way to future-proof a business. With such vast differences in accepted levels of contamination per state, the best preparation for the future and regulations coming down the pipeline is understanding contamination, addressing it at its source and harvesting disease-free cannabis.
The risk of contamination is present at every stage of the cultivation process and encompasses agricultural practices, manufacturing processes and their intersection. From cultivation to manufacturing, there are factors that can introduce contamination throughout the supply chain. A quality control infrastructure should be employed in a facility and checkpoints within the process to ensure aseptic operations.
Microbial monitoring methods can include frequent/consistent testing
Cultivators should test their raw materials, including growing substrates and nutrient water to ensure it is free of microbial contamination. Air quality plays an important role in the cultivation and post-harvest processes, especially with mold contamination. Environmental controls are essential to monitor and regulate temperature and humidity and ensure unwanted microbes cannot thrive and decrease the value of the product or make it unsafe for worker handling or consumers. Developing SOPs to validate contact surfaces are clean, using proper PPE and optimizing worker flow can all help to prevent cross-contamination and are part of larger quality assurance measures to prevent microbes from spreading across cultivars and harvests.
Methods of microbial examination include air quality surveillance, ATP surface and water monitoring, raw materials testing, and species identification. Keeping control of the environment that product is coming into contact with and employing best practices throughout will minimize the amount of contamination that is present before testing. The solution to avoiding worst case scenarios following an aseptic, quality controlled process is utilizing a safe, post-harvest kill-step, much like the methods used in the food and beverage industries with the oversight of the FDA.
The goal of the grower should be to grow clean and stay clean throughout the shelf life of the product. In order to do this, it is essential to understand the critical control points within the cultivation and post-harvest processes and implement proper kill-steps. However, if a product is heavily bio-burdened, there are methods to recover contaminated product including decontamination, remediation and destroying the product. These measures come with their own strengths and weaknesses and cannot replace the quality assurance programs developed by the manufacturer.
With more and more states fully legalizing cannabis for medical and adult use, regulation has become a hot topic for the industry – and it won’t be going away anytime soon. The markets for virtually all cannabis uses (with the exception of industrial hemp, under the Farm Bill) have manifested at the state level without the benefit of federal oversight. One of the biggest consequences of state-based programs has been striking inconsistencies in assuring public safety through the establishment of testing requirements and the licensing of third-party, independent testing laboratories. Establishing legal cannabis programs on a state-by-state basis has been from the ground up. While some states have done a better job than others, it has not been an easy process; one that typically involves adjusting to yearly legislative changes. Third-party independent cannabis testing labs seem like a logical arrangement for public safety and defensibility at the state level given the illegal federal status of cannabis, and while this arrangement has undoubtedly prevented tainted cannabis flower, extracts and products from ending up on dispensary shelves, many caveats from this arrangement have emerged, including fraud.
While most states do require ISO 17025:2017 accreditation, no uniform testing methods nor uniform contaminant testing requirements exist, and they vary considerably. We see this in several examples including the list of pesticides required for screening varying from none to over 66, screening for microbial contaminants varies from a simple presence/absence test for two human pathogens to quantitative enumeration across several enteric and fungal categories and, finally, some states adhere to the American Herbal Pharmacopeia heavy metal limits for herbs, while other states have adopted the more appropriate US Pharmacopeia inhalation limits. Some states require rigorous demonstration of method validation before licensing, while other states hand out preliminary licenses prior to submission and review of validation data packages for each analyte category.
Fraud in laboratory testing facilities is well known in the clinical setting, especially where lucrative Medicare or commercial insurance claims tempt less than honest laboratory managers to falsify results or add tests that were not ordered by a physician costing taxpayers billions of dollars annually. Fraud within cannabis testing labs is not instigated by large insurance payouts but rather by survival within individual markets where competition for clients can be fierce. Cannabis testing fraud ranges from outright collusion of testing labs with growers and producers demanding certificates of analysis (CoAs) with specific, inflated THC numbers to a testing lab handing out sweeping passing marks for contaminants in an attempt to keep clients or steal clients away from a reputable lab not willing to inflate cannabinoid values or pass on the presence of, say, chlorpyrifos, a highly toxic organophosphate pesticide, in extracts or lead in outdoor-grown hemp.
Cannabis testing labs have had little power to influence state legislators or regulators to improve industry oversight and combat fraud. From the outset of a state cannabis program, the growers and producers are placed in the driver seat. They generate the products that end up in dispensaries and generate sales that create the tax revenue that propels the industry forward. A consequence of this hierarchical arrangement has let the growers decide that the concentration of THC equates with value. This translates to the higher the THC concentration, the higher the price both wholesale and retail. Sadly, this also has been taken to mean better products yet with zero medical justification since we know virtually nothing about THC dosing, save for how our endocannabinoid system functions, which is at the nanomolar range. Now the entire cannabis industry is stuck with this unsubstantiated marketing ploy around THC that no one can now seem to escape. It is as if cigarette makers had decided early on to market their brands by how much nicotine each cigarette contained. You can see how this would have quickly led to toxic levels of nicotine.
Where do we go from here? Placing THC content as the primary valuation of cannabis is not an easy problem to solve, as there is little incentive for change. Fraudulent labs provide higher THC numbers, which increases dollars to the growers/producers and state tax coffers fill up. It’s a multi-point problem that will require a multi-point solution:
State regulators could move the focus away from THC by placing limits on the concentration of THC in products, increasing oversight of cannabis testing labs, and requiring unscheduled round-robin testing and annual review of validation data packages.
Growers and producers could place a higher emphasis on public safety and education.
Ultimately, the solution lies with the cannabis consumer through education and awareness. Cannabis end-users need to familiarize themselves with the testing regulations in their state and understand that higher THC numbers does not mean a better or more effective product. Cannabis consumers also need to understand the product on the market may or may not be tested for microbiological contaminants protecting them from pathogens. In many instances, they are paying for higher THC numbers that are not reflected in the product they just purchased.
Until cannabis is federally legalized and therefore given federal oversight, piecemeal, state-by-state regulation is going to continue. How that regulation protects the American consumer is up to the work of the industry and what we continue to prioritize.

According to Janet Woodcock, M.D., principal deputy commissioner at the FDA, they are getting more and more concerned about the popularity of delta-8 THC products sold online. “These products often include claims that they treat or alleviate the side effects related to a wide variety of diseases or medical disorders, such as cancer, multiple sclerosis, chronic pain, nausea and anxiety,” says Woodcock. “It is extremely troubling that some of the food products are packaged and labeled in ways that may appeal to children. We will continue to safeguard Americans’ health and safety by monitoring the marketplace and taking action when companies illegally sell products that pose a risk to public health.”
