The current method is inadequate, says Mark Lange, a professor in WSU’s Institute for Biological Chemistry. Regulators focus on levels of the psychoactive compound THC and just a handful of the more than 90 other cannabinoids. The industry makes various claims about different strains, from sedating indicas to invigorating sativas, Acapulco Gold to Zkittlez, but they defy objective analysis.
“There is a reason why all these strains have different names — because a lot of them are very different,” said Lange. “But some strains with different names are actually very similar. The bottom line is there is a lot of confusion.”
Lange and his colleagues analyzed genetic sequences from nine commercial cannabis strains and found distinct gene networks orchestrating each strain’s production of cannabinoid resins and terpenes, volatile compounds behind the plant’s powerful aroma.
Their research was published today in the journal Plant Physiology.
