Integrating Your LIMS System With State Tracking Systems
By Hannah O’Brien, Operations Manager, Confident Cannabis
Running a lab is hard. Running a cannabis lab is harder. Watch this webinar hosted by Confident Cannabis, the most popular and only free cannabis LIMS in the country, to learn how cannabis compliance and regulatory burdens impact analytical testing laboratories in any state, and how important purpose-built software solutions are to make their business run smoothly.
Last week, the California Bureau of Cannabis Control released their proposed emergency regulations for the industry. The Bureau, the government agency tasked with regulating California’s cannabis industry, announced the proposed emergency regulations ahead of the highly anticipated January 2018 start date.
Temporary licenses will allow businesses to operate for 120 days while their annual license application is being processed. Not surprisingly, local jurisdictions have considerable autonomy. Getting a license seems to be contingent on first getting local approval to operate. According to Josh Drayton, communications and outreach director at the California Cannabis Industry Association (CCIA), working with local governments will be crucial to making progress. “Now that the Brown Administration has created the framework for medical and adult use cannabis, the main challenge we face as an industry is getting local municipalities to move forward with regulations,” says Drayton. “California has a dual licensing process which means that cannabis operators must receive a local permit/license/authorization before being able to apply for a state license. A majority of California cities and counties have yet to finalize their regulations which will delay state licensing.”
The initial reactions to these proposed regulations seem positive, given that this is a culmination of efforts over several years. “The California Cannabis Industry Association welcomes the release of the emergency regulations,” says Drayton. “These regulations represent years of hard work and collaboration between the administration, the regulating departments, and the cannabis industry.”
A-type licenses are for businesses in the adult-use market, while M-type licenses are for the medical market. Laboratory licenses don’t have this distinction, as they can test both medical and adult-use products.
The record keeping and security requirements seem relatively straightforward, requiring normal surveillance measures like 24-hour video, commercial-grade locks and alarm systems. The rules also lay out guidelines for disposing of waste, including securing it on the premises and not selling it.
Distributor licenses appear to have a number of compliance documentation requirements, such as arranging for all product testing, quality assurance and packaging and label accuracy. “Cannabis and cannabis products must pass through a distributor prior to being sold to customers at a retail establishment,” reads the overview the Bureau published. There is also a transport-only distributor license option. Those regulations appear to be more comprehensive than others, with a number of regulations pertaining to appropriate transportation and security measures.
Everything has to be packaged before it gets to retail; Retailers are not allowed to package or label cannabis products on premises. Microbusiness licenses will be available, which should be an exciting new development to follow as the market matures.
The state will require ISO 17025 accreditation for testing labs. A provisional license is required for a lab to operate in the short term, expiring after 12 months. Laboratory personnel are required to go in the field and do the sampling. Documentation requirements, sample sizes, sampling procedures and storage and transportation rules are also laid out.
Testing labs are required to test for cannabinoids, foreign material, heavy metals, microbial impurities, mycotoxins, moisture content and water activity, residual pesticides, residual solvents and processing chemicals and terpenoids (terpenes). Infused and edible products are required to be tested for homogeneity in THC and CBD concentrations as well. Drayton and the CCIA welcome these new testing regulations, hoping it might improve overall public safety. “We believe that these regulations will address public health issues by mandating the testing of all cannabis products,” says Drayton. “The evolution of the cannabis industry will continue, and we will continue to advocate for good policy that creates solutions for the problems that arise. I believe that we will be visiting and revisiting cannabis regulations for many years to come.”
Certificates of analysis (COA) will be required, showing whether a batch passes or fails testing requirements. Harvest batches that fail testing can be processed for remediation. “Testing laboratories are required to develop and implement a quality assurance program that is sufficient to ensure the reliability and validity of the analytical data produced by the laboratory,” reads the statement on QA and QC.
The Bureau, at the end of their regulatory overview document, lays out some possible enforcement actions, disciplinary actions and citations that could come from noncompliance. “These emergency regulations create a framework for both medical and adult use consumers,” says Drayton. “January 1, 2018 will be the first date that adults 21 years and older will be able to purchase cannabis without a medical card.”
In the coming weeks, we’ll be breaking down and analyzing the other proposed emergency regulations that the state released. Stay tuned for a breakdown of the California Department of Food & Agriculture (CDFA) regulations on cannabis cultivation, as well as The California Department of Public Health (CDPH) cannabis manufacturing regulations.
KIND Financial, a technology and compliance software solutions provider in the cannabis industry, is launching a new e-commerce and payment processing platform in Canada. According to the press release, they are partnering with a Canadian bank to launch the KIND Seed to Payment platform, which is essentially an e-commerce gateway integrated with their compliance software, KIND’s RegTech platform.
David Dinenberg, founder and CEO of KIND Financial, says this is an approach to help alleviate the cannabis industry’s banking woes. “We’ve been very focused on a global vision and taking a strategic approach towards solving the cannabis industry’s largest problem – banking,” says Dinenberg. “Not only have we built a broad portfolio of finance and compliance solutions with a high-level of technical sophistication, but we’ve made a strong commitment to security and compliance, which is evident through our partnership with Microsoft.” A little over a year ago, they entered a partnership with Microsoft to utilize their cloud-based solutions for government traceability software.
According to the press release, the software has regulatory and security features built in, such as age and identity verification, which can help companies comply with security and chain of custody regulations. “Our mission is to ensure business and technological growth for all constituencies within the cannabis industry while ensuring full compliance with evolving regulations, and that’s why we’re thrilled to make these services available to our great neighbors in the north,” says Dinenberg. “We understand compliance will be a critical issue for some time to come, but with our solution, all providers and their partners can focus on the job at hand while keeping in line with regulatory mandates.”
KIND Financial has not done much work in Canada previously, but this could be a sign of a greater push for international expansion. “We’re excited to be working in a new country to boost the Canadian cannabis industry in a safe and regulated manner, and we look forward to expanding into other markets overseas,” says Dinenberg. The press release says the new platform is designed to work with different languages and foreign currencies, including the euro and Australian dollar, which could help Canadian producers enter emerging markets.
In addition to their announcement of the KIND Seed to Payment platform, the company also announced they will be rolling out a mobile payment system called KIND Pay, a digital payment option for consumers that will accept Visa and MasterCard. They anticipate that KIND Pay will launch before the end of this year.
Back in April of 2016, the Colorado Legislature passed HB 1436 in an effort to make infused products less appealing to children. On October 1st, 2017, the new law goes into effect, which will prohibit the sale of edibles in the shape of a human, animal or fruit.
Colorado has a history of regulating the market like this, with laws designed to limit the dosing, consistency and appeal of edibles to children. In 2015, regulators placed a 100-milligram cap on THC in infused products, separated into 10-milligram servings. In 2016, regulators began requiring the THC stamp on edibles, a symbol with a clear representation of what the product contains.
Some in the industry are welcoming of these new laws, while others think it might be overregulation. Regardless, manufacturers that have previously produced things like fruit candies or gummy bears now need to update their processes to use non-descript shapes for their products in order to stay compliant.
Bob Eschino, founder and president of Incredibles, an infused product manufacturer in Colorado, says these rules are not very effective at preventing kids from obtaining edibles, but it could help. “I believe consumer protection comes from CRP [child-resistant packaging], proper labeling, education and safe storage,” says Eschino. “CDPHE said themselves that stamping or shaping the products is the least effective way to prevent accidental ingestion. It’s a step that will add to consumer protection in a small way, but every little bit helps for now.” There are a number of more effective measures that regulators in Colorado take to prevent edibles from getting in the hands of children, such as child-resistant packaging, prohibiting advertising of cartoon characters, requiring opaque packaging and warning messages on labels.
According to Peggy Moore, partner of Love’s Oven, an infused product manufacturer, and board president of the Cannabis Business Alliance, the major change companies need to make to stay compliant is ordering new molds. “Depending on the quantity ordered, molds can cost $10,000 or more to fabricate and produce.,” says Moore. “If a company was not using molds previously there is also training that may be required to orient production staff on technique for making molded confections.” She says there are still plenty of options for manufacturers to use like botanical shapes (a cannabis leaf, for example), circles, squares, rectangles and other shapes.
Her company, Love’s Oven, makes caramels, baked goods, crackers and other non-descript shapes already. “At this point I am not aware of any manufacturers who are not already compliant with this rule in advance,” says Moore. “The most common solution is to move to a square, circle or other shape utilizing molds. “ Moore believes it is a producer’s duty to make products that are not enticing to children. “Regardless of the industry (alcohol, cannabis, pharma) I think we should exercise great caution to not produce products that are targeting children,” says Moore. “While I would love to see manufacturers self-regulate in this regard, clearly some guardrail regulations are needed at this point.”
In addition to the rule on using non-descript shapes, HB 1436 prohibits the use of additives in retail cannabis products that are designed to make it addictive, more appealing to children or misleading consumers. The rule does, however, exclude common baking and cooking ingredients. There is also a stipulation that permits local fire departments to perform annual fire inspections at cannabis cultivation facilities.
According to a press release, the National Association of Cannabis Businesses (NACB) launches today, becoming the first self-regulatory organization (SRO) for the cannabis industry. With their mission to help compliance, transparency and growth of cannabis companies, they will lead member businesses in establishing voluntary national standards, addressing issues like advertising and financial integrity.
A team of experienced legal regulatory professionals will lead member businesses through a process of developing those standards. Andrew Kline, president of the NACB, was a senior advisor to Vice President and then-Senator Joseph Biden, served as an Assistant United States Attorney in the District of Columbia and in the Enforcement Bureau of the FCC. Their chief executive officer, Joshua Laterman, began working on NACB three years ago, but before that he had two decades of experience as general counsel at global financial and investment institutions. Doug Fischer, their chief legal officer and director of standards, spent the past nine years in cannabis law and financial regulation and enforcement at the law firm Cadwalader Wickersham and Taft.
According to the press release, SROs have proven to be effective in other industries at limiting government interference and overregulation, while preserving public safety. FINRA (Financial Industry Regulatory Authority) is an example of an SRO that serves the financial industry. It is a non-governmental organization that helps regulate member brokerage firms and exchange markets, working to help their members stay compliant with regulations set by the Securities and Exchange Commission. Much like the rapid growth of the financial markets over the past 30 years, the cannabis industry is experiencing exponential growth while regulators try to keep up.
“The cannabis industry is on a historical growth trajectory that is expected to continue for years to come, but even the most established, well-run businesses recognize that the future favors the prepared,” says Josh Laterman, CEO of NACB. “As other industries have experienced with their SROs, establishing and committing to voluntary national standards will enable cannabis business owners to demonstrate impeccable business and compliance practices to consumers, regulators, banks and investors.”
According to Doug Fischer, chief legal officer and director of standards, they will focus on a variety of topics that align with the federal enforcement priorities. So these standards might not cover some of the product safety and quality aspects that ASTM International and FOCUS touch on, rather addressing issues like advertising, financial integrity, preventing diversion across state lines, prevention of youth use and corporate responsibility. Another important distinction to make is that an organization like ASTM International sets standards, but the NACB as an SRO is tasked with enforcing them as well.
“From our perspective, businesses have been having a hard time navigating the complex state regulations, particularly those operating in multiple states,” says Fischer. “That is further complicated by the current administration not solidifying their stance on recreational cannabis.” The Cole Memo put out under the Obama Administration set clear federal enforcement priorities, allowing cannabis businesses and states to identify ways to avoid federal government interference or prosecution.
The current administration has done nothing but fuel regulatory uncertainty. This is particularly important given this week’s news regarding the leaders at the Justice Department making inflammatory and threatening statements regarding legal medical cannabis. “It causes these businesses, who should be focused on their own day-to-day operations, instead focusing on complying with what they think the federal government wants and regulatory compliance with state regulations,” says Fischer. “We can help solve that problem by making it easier for companies to become compliant, not only with state regulations but federal guidance as well. This has been proven by other SROs, that if we set our own standards and abide by them, federal regulators might be guided by the industry’s self-policing in determining how to regulate the cannabis industry.” According to Andrew Kline, it could also provide a window of opportunity for better banking access.
The founder and CEO, Joshua Laterman, used to work in the banking industry and recognized the need for a cannabis industry SRO. “He saw an incredible opportunity in a projected $50 billion market by 2026, and as a former banker he saw the opportunity for banks to do business in the industry, but they don’t know who to trust,” says Kline. “Starting a self regulatory organization can help fill that void, allowing companies to identify and put a stamp of approval on a segment of the population that is uber-compliant, therefore giving banks a view into who they should and shouldn’t do business with.” While it won’t immediately resolve the many issues associated with cannabis businesses’ accounting, the NACB could be a major help to smaller businesses looking to prove their worth. “The important point here is that based on the experience of our team, we know what is important to the federal government, and we understand that members will be shaping standards with us, so we will also guide them to federal priorities,” says Kline.
Fischer says a self-regulatory organization is always driven by the industry and needs of the members, but they have the added unique challenge of working in a web of competing governmental interests. “Self-regulatory organizations can shape the future of regulation; we don’t know if or when federal prohibition will end, but if it does, the government is going to look at a variety of areas for regulations,” says Fischer. “We might be able to help shed light on our self-regulating nature and if we can demonstrate the best practices for specific areas, states and even the federal government could look to that, giving our members an advantage.” According to their press release, licensed cannabis growers, dispensaries or any other ancillary business may apply to become members. Some of the founding members include Buds & Roses, Etain, Green Dot Labs, Local Product of Colorado, Matrix NV, Mesa Organics, among others.
Oxygen plays an integral role in plant photosynthesis, respiration and transpiration. Photosynthesis requires water from the roots making its way up the plant via capillary action, which is where oxygen’s job comes in. For both water and nutrient uptake, oxygen levels at the root tips and hairs is a controlling input. A plant converts sugar from photosynthesis to ATP in the respiration process, where oxygen is delivered from the root system to the leaf and plays a direct role in the process.
Charlie Hayes has a degree in biochemistry and spent the past 17 years researching and designing water treatment processes to improve plant health. Hayes is a biochemist and owner of Advanced Treatment Technologies, a water treatment solutions provider. In a presentation at the CannaGrow conference, Hayes discussed the various benefits of dissolved oxygen throughout the cultivation process. We sat down with Hayes to learn about the science behind improving cannabis plant production via dissolved oxygen.
In transpiration, water evaporates from a plant’s leaves via the stomata and creates a ‘transpirational pull,’ drawing water, oxygen and nutrients from the soil or other growing medium. That process helps cool the plant down, changes osmotic pressure in cells and enables a flow of water and nutrients up from the root system, according to Hayes.
Roots in an oxygen-rich environment can absorb nutrients more effectively. “The metabolic energy required for nutrient uptake come from root respiration using oxygen,” says Hayes. “Using high levels of oxygen can ensure more root mass, more fine root hairs and healthy root tips.” A majority of water in the plant is taken up by the fine root hairs and requires a lot of energy, and thus oxygen, to produce new cells.
So what happens if you don’t have enough oxygen in your root system? Hayes says that can reduce water and nutrient uptake, reduce root and overall plant growth, induce wilting (even outside of heat stress) in heat stress and reduce the overall photosynthesis and glucose transfer capabilities of the plant. Lower levels of dissolved oxygen also significantly reduce transpiration in the plant. Another effect that oxygen-deprived root systems can have is the production of ethylene, which can cause cells to collapse and make them more susceptible to disease. He says if you are having issues with unhealthy root systems, increasing the oxygen levels around the root system can improve root health. “Oxygen starved root tips can lead to a calcium shortage in the shoot,” says Hayes. “That calcium shortage is a common issue with a lack of oxygen, but in an oxygen-deprived environment, anaerobic organisms can attack the root system, which could present bigger problems.”
So how much dissolved oxygen do you need in the root system and how do you achieve that desired level? Hayes says the first step is getting a dissolved oxygen meter and probe to measure your baseline. The typical dissolved oxygen probe can detect from 20 up to 50 ppm and up to 500% saturation. That is a critical first step and tool in understanding dissolved oxygen in the root system. Another important tool to have is an oxidation-reduction potential meter (ORP meter), which indicates the level of residual oxidizer left in the water.
Citing research and experience from his previous work, he says that health and production improvements in cannabis plateau at the 40-45 parts-per-million (ppm) of dissolved oxygen in the root zone. But to achieve those levels, growers need to start with an even higher level of dissolved oxygen in a treatment system to deliver that 40-45 ppm to the roots. “Let’s say for example with 3 ppm of oxygen in the root tissue and 6ppm of oxygen in the surrounding soil or growing medium, higher concentrations outside of the tissue would help drive absorption for the root system membrane,” says Hayes.
Reaching that 40-45 ppm range can be difficult however and there are a couple methods of delivering dissolved oxygen. The most typical method is aeration of water using bubbling or injecting air into the water. This method has some unexpected ramifications though. Oxygen is only one of many gasses in air and those other gasses can be much more soluble in water. Paying attention to Henry’s Law is important here. Henry’s Law essentially means that the solubility of gasses is controlled by temperature, pressure and concentration. For example, Hayes says carbon dioxide is up to twenty times more soluble than oxygen. That means the longer you aerate water, the higher concentration of carbon dioxide and lower concentration of oxygen over time.
Another popular method of oxidizing water is chemically. Some growers might use hydrogen peroxide to add dissolved oxygen to a water-based solution, but that can create a certain level of phytotoxicity that could be bad for root health.
Using ozone, Hayes says, is by far the most effective method of getting dissolved oxygen in water, (because it is 12 ½ times more soluble than oxygen). But just using an ozone generator will not effectively deliver dissolved oxygen at the target levels to the root system. In order to use ozone properly, you need a treatment system that can handle a high enough concentration of ozone, mix it properly and hold it in the solution, says Hayes. “Ozone is an inherently unstable molecule, with a half-life of 15 minutes and even down to 3-5 minutes, which is when it converts to dissolved oxygen,” says Hayes. Using a patented control vessel, Hayes can use a counter-current, counter-rotational liquid vortex to mix the solution under pressure after leaving a vacuum. Their system can produce two necessary tools for growers: highly ozonized water, which can be sent through the irrigation system to effectively destroy microorganisms and resident biofilms, and water with high levels of dissolved oxygen for use in the root system.
