The evolution of cannabis science continues to move at a lightning pace. During the last 18 months, there has been a significant shift from cannabis safety to cannabinoid efficacy and disease applications.  Historically, cannabis science has not followed a typical pharmaceutical model but evidence suggests that this field is evolving. This shift will affect most verticals in the industry including cultivation, production and manufacturing, and certainly quality assurance laboratories. 

In addition to the impact on existing cannabis verticals, the evolution of science in the industry will create opportunities for entirely new business models such as cannabinoid creation outside traditional cultivation, the development of clinical research and myriad products for and from this work, and the introduction of novel compounds related to the endocannabinoid system.

Testing Cannabis for microbials is one way to ensure the cannabis industry is growing and delivering quality products.  Two basic microbiology tests, total aerobic count and total yeast and mold testing help growers and processors understand the bioburden on the product and whether or not there is a potential problem.  Learn more about how this simple test has been used for decades in quality control microbiology testing.

Presenter: Ben Katchman, VP of Research and Development

Background: Yeast and mold testing is used in the cannabis industry to determine the cleanliness of raw and finished products being provided to consumers. In response to regulatory requests, the AOAC Research Institute launched an Emergency Response Validation (ERV) program to certify methods for the enumeration of viable yeast and mold in dried cannabis flower.

Objective: To conduct a matrix study of the PathogenDx QuantX Fungal One Step method in dried cannabis flower (delta 9-tetrahydrocannabinol >0.3%; 10 g sample size).

Methods: The QuantX assay was validated following AOAC Official Methods of Analysis Appendix J validation guidelines and the AOAC ERV protocol for yeast and mold count in cannabis flower. Replicates at four different levels of natural yeast and mold contamination were tested at two test thresholds. Inclusivity and exclusivity testing for yeast and mold species associated with cannabis was performed.

Results: In inclusivity testing, all yeast and mold strains tested produced positive results and exclusivity strains were correctly excluded. In matrix testing, there were no significant differences between presumptive and confirmed results for any contamination level or test threshold as determined by probability of detection analysis.

Conclusions: No statistical difference was detected when comparing the QuantX method to results by traditional plating on Dichloran Rose Bengal Chloramphenicol (DRBC) agar plates.

Highlights: The QuantX method offers the same day detection of total yeast and mold in cannabis flower.

Without robust method development, cannabis potency testing is subject to potentially troublesome reproducibility issues. Two parameters that are often at play with potency methods are temperature and mobile phase pH. Temperature is an instrument capability issue, however the more significant issue from a method development standpoint is mobile phase pH. Without control of mobile phase pH at a value well-removed from an analyte pKa, reproducibility issues can be expected to follow.

We discussed these two critical parameters for cannabinoid testing, followed by a case study on an approach to lowering the cost of performing this method. Cost is another parameter often considered with method development, and solvents attribute to this overall cost. We leveraged the choice of mobile phase to decrease overall solvent cost for analysis of 17 cannabinoids.

Aerosol analysis of electronic nicotine delivery systems (ENDS) has become an important test for regulating commercially available tobacco products. ENDS are widely accepted in society for tobacco use; therefore, it was only natural that vaporizers emerged in the cannabis marketplace as a popular way to consume cannabis flower and extracts. Currently, states within the United States do not regulate the testing of cannabis vapor and smoke. However, starting on January 1st, 2022, the Colorado Marijuana Enforcement Division will require aerosol testing from cannabis vape products to analyze what consumers are potentially inhaling. This new cannabis testing area is not support by a lot of methods and data, so insights come from previous work on electronic cigarette aerosol and liquid. A simple sampling setup was developed to draw electronic cigarette aerosol into a thermal desorption (TD) tube, which was then thermally extracted and analyzed via GC-MS method. This approach was able to provide detectable levels of volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs), which were not detectable in their liquid form. Both methods are able to be done on one GC, two detectors, and one analytical column (Rtx-VMS), thereby reducing required resources and affording easy comparison of results.
