“Whole broad categories of CBD-rich cannabis strains have emerged since the serendipitous rediscovery of CBD by Northern California growers in late 2009. There are a handful of CBD-dominant strains with little THC (just the opposite of what’s readily available on the recreational black market and the medical marijuana grey market). And there are also more balanced strains with roughly equal — or significant — amounts of both CBD and THC. Tested several times by several analytical labs, the initial CBD-rich strains (such as Harlequin, Jamaican Lion, and Omrita Rx) ranged from 8-9% CBD and 5.5-6% THC — about a 3:2 ratio. Yet anecdotal evidence suggested differing effects conferred by these strains. It seems likely that these differences lay in their respective terpenoid profiles.
Another strain found in the early going, Women’s Collective Stinky Purple, registered ten times the amount of CBD than THC. This plant somehow got lost in the grassroots shuffle. But a few more strains with a similar CBD-dominant phenotype would soon be identified and cloned for distribution. These CBD-dominant strains (with names such as Cannatonic, Oracle, AC/DC, and CBDX) are being grown largely to harvest cannabidiol for making oil extracts.
It appears that some of these CBD-dominant strains have different names but are actually the same plant. The LA-based Werc Shop analyzed the terpene content of two CBD-dominant strains, “Oracle” and “AC/DC,” and found that they were identical. “A terpene analysis is like a fingerprint,” explains Werc Shop’s president Jeff Raber. “It can tell you if it’s the same strain with different names. We can see strains going by different names that have the same terpene profile. We now know the strains are identical.”
