In the first part of this series, we spoke with Michelle Bradac, senior accreditation officer at A2LA, to learn the basics of cannabis laboratory accreditation. In the second part, we sat down with Roger Brauninger, A2LA Biosafety Program manager, to learn why states are looking to lab accreditation in their regulations for the cannabis industry. In the third part, we heard from Michael DeGregorio, chief executive officer of Konocti Analytics, Inc., discussing method development in the cannabis testing industry and his experience with getting accredited.

In the fourth and final part of this series, we sit down with Susan Audino, Ph.D., an A2LA lead assessor and instructor, laboratory consultant and board member for the Center for Research on Environmental Medicine in Maryland. Dr. Audino will share some insights into method validation and the most technical aspects of laboratory accreditation.

Susan Audino, Ph.D.

Susan Audino obtained her Ph.D. in Chemistry with an analytical chemistry major, physical and biochemistry minor areas. She currently owns and operates a consulting firm to service chemical and biological laboratories. Susan has been studying the chemistry and applications of cannabinoids and provides scientific and technical guidance to cannabis dispensaries, testing laboratories and medical personnel. Dr. Audino’s interest most directly involves cannabis consumer safety and protection, and promotes active research towards the development of official test methods specifically for the cannabis industry, and to advocate appropriate clinical research. In addition to serving on Expert Review Panels, she is also chairing the first Cannabis Advisory Panel and working group with AOAC International, is a member of the Executive Committee of the ASTM Cannabis Section and has consulted to numerous cannabis laboratories and state regulatory bodies.

CannabisIndustryJournal: What are the some of the most significant technical issues facing an accreditation body when assessing a cannabis-testing laboratory?

Susan: From the AB perspective, there needs to be a high level of expertise to evaluate the merits and scientific soundness of laboratory-developed analytical test methods. Because there are presently no standard or consensus test methods available, laboratories are required to develop their own methods, which need to be valid. Validating methods require a rigorous series of tests and statistical analyses to ensure the correctness and reliability of the laboratory’s product, which is– the test report.

CIJ: When is method validation required and how does this differ from system suitability?

Susan: Method validation is required whenever the laboratory modifies a currently accepted consensus or standard test method, or when the laboratory develops its own method. Method validation is characterized by a series of analytical performance criteria including determinations of accuracy, precision, linearity, specification, limit of detection, and limit of quantitation. The determination of system suitability requires a series of deliberate variations of parameters to ensure the complete system, that is all instrument(s) as well as the analytical method, is maintained throughout the entire analytical process. Traditionally, method validation has been referred to as “ruggedness” and system suitability as “robustness.”

CIJ: What are the most important aspects of method validation that must be taken into account? 

Susan: In keeping with the FDA guidelines and other accepted criteria, I tend to recommend the International Conference on Harmonization (ICH), particularly Q 2A, which is a widely recognized program that discusses the pertinent characteristics of method validation. This include: method specification, linearity, range, accuracy, and precision (e.g., repeatability, intermediate precision, reproducibility). As mentioned earlier, system suitability is also a critical element and although related to method validation, does require its own protocol.

CIJ: What three areas do you see the laboratory having the hardest time with in preparing for accreditation? 

Susan: My responses to this question assume the laboratory employs appropriate instruments to perform the necessary analyses, and that the laboratory employs personnel with experience and knowledge appropriate to develop test methods and interpret test results.

  • By and large, method validation that is not appropriate to the scope of their intended work. Driving this is an overall lack of information about method validation. Oftentimes there is an assumption that multiple recoveries of CRMs constitute “validation”. While it may be one element, this only demonstrates the instrument’s suitability. My recommendation is to utilize any one of a number of good single laboratory validation protocols. Options include, but are not limited to AOAC International, American Chemical Society, ASTM, and ICH protocols.
  • Second is the lack of statistically sound sampling protocols for those laboratories that are mandated by their governing states to go to the field to sample the product from required batches. Sampling protocols needs to address the heterogeneity of the plant, defining the batch, and determining/collecting a sample of sufficient quantity that will be both large enough and representative of the population, and to provide the laboratory an adequate amount from which to sub-sample.
  • Third, sample preparation. This is somewhat intertwined with my previous point. Once an appropriate sample has been collected, preparation must be relevant to the appropriate technology and assay. It is unlikely that a laboratory can perform a single preparation that is amenable to comprehensive testing.

Oregon Cannabis Lab Accreditation Program Gets Help, Problems Addressed

Last week, news of problems facing Oregon’s cannabis laboratory accreditation program surfaced, leading some to speculate about possible delays for the recreational cannabis market. According to The Register-Guard, ORELAP administrator Gary Ward believed the program was “on the precipice of collapse.”

oha_logo_lrgAccording to Jonathan Modie, spokesman for the Oregon Health Authority (OHA), the Oregon Environmental Laboratory Accreditation Program (ORELAP) was anticipating over 30 cannabis laboratories applying for accreditation and they doubled their staff from two to four to prepare for the uptick in applications.

In June, the agency had zero labs applying for accreditation but within two months, 37 labs applied. However, the Oregon Department of Environmental Quality (DEQ) just provided three additional staff members on Monday to help with the application process, says Modie.

Some believe the issues could mean the state may not have enough accredited labs by October 1st, when the recreational cannabis market is expected to go into full swing. “It is difficult to say exactly how many labs we can accredit by October 1,” says Modie. “We have seven labs today which would bring it to nine labs waiting for assessment, but our goal is to get as many labs assessed and hopefully accredited as soon as possible.”

With the additional staff members, Modie is hopeful this will jumpstart the program. “We really appreciate our collaboration with the DEQ and look forward to boosting our capacity a bit to help us get through this busy time,” says Modie.

Part of the reason some laboratories might have trouble meeting prerequisites is simply because the requirements are very strict. “The process involves submitting a quality manual, standard operating procedures, method validation, submitting proficiency testing data and finally undergoing an ORELAP assessment by our staff, so it is a very rigorous process,” says Modie. “This speaks to our concern for making sure they have the right systems in place so public health is protected.” Modie said there were at least three labs that did not pass the assessment.

Bethany Sherman, chief executive officer of OG Analytical, believes the hardest part of the process involves getting accredited for testing pesticides. OG Analytical, based in Eugene, Oregon, has already received their accreditation, one of the first to do so. “The pesticide testing requires our most expensive instrumentation and the sample preparation for testing pesticides is the most time consuming,” says Sherman. “Not only does it require very specific instrumentation, it also requires a real know-how and expertise to ensure we are cleaning samples appropriately, minimizing background noise and looking at the pesticides in trace quantities.” According to Sherman, laboratories are also left to their own devices to develop methodologies specifically for the cannabis matrix, adding to the difficulties.

Rodger Voelker, Ph.D., lab director at OG Analytical, seems confident that the state will be able to handle it. “It is a relief they were able to get some resources from the DEQ and I think the state will not allow a program with this kind of importance to fall apart,” says Voelker. He believes after this initial phase of putting the program in place, the workload will go down. “It is easier to maintain a program than it is to implement,“ adds Voelker. In his eyes, it is crucial for the program to require rigorous science. “People are forced to reconcile that there is a tremendous amount of controls to be considered to produce legally defensible data and I think it is great that the requirements are so strict.”

The OHA’s job is to essentially safeguard public health and they do not want to leave any stone unturned when it comes to potential contamination, says Modie. “This is not just about getting as many labs accredited as possible, this is about protecting public health.”

Nic Easley, chief executive officer at Comprehensive Cannabis Consulting (3C), delivered the keynote address at the first annual Cannabis Labs Conference, co-located with Pittcon. Easley begins with a discussion of the 2014 milestone where Colorado and Washington legalized recreational cannabis, opening the floodgates for a diverse range of products and business opportunities in quality and safety testing. With members of his team sitting on the Colorado Department of Agriculture’s Pesticide working group, they are working with industry leaders and regulators to comprehensively write the standards. “The industry gets regulated in 2014 in Colorado with a total of $2.7 billion in sales in the first year of the industry’s history,” says Easley. “We have this giant influx of business, but without process validation, good agricultural practices and proper SOPs, each state is left to fend for themselves to write regulations.”

With multiple states now requiring third-party certification as part of licensing cannabis laboratories, there is a large role for laboratory accreditation in the cannabis industry. Using method validation can prove that your data is reproducible and that you have robust methods for sample preparation and calibration. All of these tools are instrumental in getting a laboratory accredited.
