Little variety in THC levels with different cannabis strains, says UBCO study

Kelowna - The research shows most strains, regardless of their name, had the same amount of THC.

A rose by any other name is still a rose. The same, it turns out, can be said for cannabis.

Newly published research from UBC害羞草研究所檚 Okanagan campus has determined that many strains of cannabis have virtually identical levels of tetrahydrocannabinol (THC) and cannabidiol (CBD), despite their unique street names, according to a UBCO news release.

害羞草研究所淚t is estimated that there are several hundred or perhaps thousands of strains of cannabis currently being cultivated,害羞草研究所 says professor Susan Murch, who teaches chemistry at UBC Okanagan. 害羞草研究所淲e wanted to know how different they truly are, given the variety of unique and exotic names.害羞草研究所

Cannabis breeders have historically selected strains to produce THC, CBD or both, she explains. But the growers have had limited access to different types of plants and there are few records of the parentage of different strains, the release said.

害羞草研究所淧eople have had informal breeding programs for a long time,害羞草研究所 Murch says. 害羞草研究所淚n a structured program, we would keep track of the lineage, such as where the parent plants came from and their characteristics. With unstructured breeding, which is the current norm, particular plants were picked for some characteristic and then given a new name.害羞草研究所

Until now, the chemical breakdown of many strains has been unknown because of informal breeding, the release said.

Elizabeth Mudge, a doctoral student working with Murch and Paula Brown, Canada Research Chair in Phytoanalytics at the British Columbia Institute of Technology, examined the cannabinoid害羞草研究所攁 class of chemical compounds that include THC and CBD害羞草研究所攑rofiles of 33 strains of cannabis from five licensed producers.

The research shows that most strains, regardless of their origin or name, had the same amount of THC and CBD. They also discovered that breeding highly potent strains of cannabis impacts the genetic diversity within the crop, but not THC or CBD levels, the release said.

However, Mudge says that they found differences in a number of previously unknown cannabinoids 害羞草研究所 and these newly discovered compounds, present in low quantities, could be related to pharmacological effects and serve as a source of new medicines.

Currently licensed producers are only required to report THC and CBD values. But Murch says her new research highlights that the important distinguishing chemicals in cannabis strains are not necessarily being analysed and may not be fully identified, the release said.

Murch says while patients are using medical cannabis for a variety of reasons, they actually have very little information on how to base their product choice. This research is a first step towards establishing an alternative approach to classifying medical cannabis and providing consumers with better information.
