GB Sciences Study Shows Nevada’s Cannabis Cultivar Names Have No Correlation to Active Ingredients

What consumers see is not what they get: Study finds almost no chemical diversity in Nevada’s cannabis varieties

LAS VEGAS, March 28, 2019 /PRNewswire/ — GB Sciences, Inc. (OTCQB: GBLX) today announced results from a new study that shows only three chemical varieties of cannabis were sold in the Nevada dispensaries between January 2016 and June 2017– despite nearly 400 different “strain names” appearing on product packaging.

Co-authored by GB Sciences, Chaminade University, Makai Biotechnology and Digipath Labs, and published in the journal Cannabis and Cannabinoid Research, the study reveals extremely low chemical diversity within the cannabis varieties sold in the Nevada market during its medical-only phase. Over 93% of the samples tested were from a single chemical variety, high in tetrahydrocannabinol but without significant amounts of other cannabinoids.

“There is no protection for patients from inadvertent or intentional mislabeling of cannabis cultivars. Many cannabis samples with vastly different chemical profiles were labeled with identical cultivar names. And identical samples were often labeled with a huge variety of cultivar names,” said Dr. Andrea Small-Howard, CSO of GB Sciences.

Medical cannabis patients benefit from having access to cannabis-products with a variety of combinations of clinically-beneficial compounds, including cannabinoids and terpenes. So, the lack of labeling accuracy directly impacts patients. “If names were tied to active ingredients, doctors could recommend products with a higher degree of confidence and patients would have information that is vital to finding products that gave consistent results,” said Dr. Small-Howard.

To evaluate the chemical diversity of cannabis products available to medical cannabis patients in Nevada, the study examined the relationship between chemical profiles (cannabinoids and terpenes) and genetic markers from 2,662 cannabis samples, collected during the period when Nevada had a purely medical market, and the corresponding 396 cannabis cultivar names reported by the cannabis breeders.

Patients who would benefit from specialty products, such as significant levels of “minor” cannabinoids, were not well served during the sampling period. Alternatively, lack of patient and physician education on the medical benefits of the minor cannabinoids and terpenes may have also contributed to the dominance of THC in this medical market. Only intervention in the form of state regulation could have addressed this situation.
