Differentiating cannabis products within the brands of the legalized adult use markets
W ithin the framework of Bill C-45, Canada is positioned to become the global leader in the legal cannabis economy and
global exporter. The enactment of this Canadian Cannabis Act provides legal access to marijuana and to control and
regulate its production, distribution and sale. The primary objective of Health Canada’s regulatory policy bears stringencies
with respect to public health and safety and strict requirements for quality assurance, record keeping and mandatory testing
by 3 rd party laboratories for product contamination. This opens an opportunity for advancing analytical development for
cannabis metabolite profiling of active natural products and bleeds through to the accurate quantitative reporting of pesticides,
mycotoxins and heavy metalloids that serve regulatory audit to clear products for sale. A complete LC-MS/MS workflow is
described to quantitate 14 cannabinoids and screen for over 40 terpenoids to fingerprint various top cannabis dried flower
brands from the large enterprise-producers in a method that is delivered in under 15 mins of analytical run time using a dual
ESI and APCI ionization strategy. A wide linear dynamic range of 0.03 to 90% measurement (104 orders LDR) of cannabinoid
per LC-MS injection can be reported to provide a more accurate view for product labeling and dosing recommendations.
Terpene expression and metabolite measurement in plant cultivars are becoming less challenging with newly identified
terpene synthases and availability of new mono-terpenes and sesquiterpene standards. It is of high interest for results of these
metabolite profiling experiments to be correlated with plant cultivation parameters to achieve quality control and strengthen
the consumer's experience with a brand of cannabis and differentiate products for retail. Furthermore, pesticide residue analysis
in cannabis flower and oil formulations has been developed to meet the reporting requirements of Health Canada’s banned
pest control ingredients list. With UHPLC linked tandem mass analysis covering all of the 96 banned pesticides except for 11
compounds best suited by GC separation, it is possible to achieve a validated cannabis product certificate of analysis for issuance
to cannabis licensed producers in rapid turn-around. Analytical method details include LC separation using the Raptor Restek
Column, Raptor Biphenyl and newly available mixtures of pesticide standards to meet the Canadian Pest Management Agency’s
list of required pesticide maximum residual levels (down to 10 ppb in most cases). The addition of mycotoxins and other
organo-contaminants can also be inserted into our methods with the use of optimized Scheduled MRM mass spec scanning
techniques. The assembly of all the potency and ingredients data collection possible can provide information to consumers and
track benefits to the cannabis producers stride to bring powerful brands to the global cannabis market.
Biography
Brigitte Simons is a business development executive in support of leading-edge laboratory services and data management tools for the development of safe
cannabis. Bridging expertise within analytical science, pharma drug development and environmental testing – Brigitte have a professional track record for laboratory
testing instrumentation, software and sample contract design for the Canadian federal agencies, such as Canadian Food Inspection, Health Canada, Agriculture
Canada and Environment Canada. She spent over 6 years working in the Drug Toxicology and Analysis Division at Health Canada in a mass spectrometry facility
testing. She completed two post-doctoral fellowships at the Clinical Sciences Hospital of the National Heart, Blood & Lung Institute within the famous NIH campus
in Maryland, USA. Continuing on in lab specialties, Brigitte then joined SCIEX, a global instrumentation vendor for hardware and software for mass spectrometry.
With over 15 years experience with operating mass spectrometers, Brigitte managed Canadian federal and provincial government sales for full laboratory services,
covering clinical, forensics to product health and environmental safety. Prior to working abroad, Brigitte received her Ph.D. in Chemical Biology at the University of
Ottawa in a joint chemistry program with drug pharmacology at Health Canada.
