Marijuana legalization is looming in Canada, but what’s in today’s weed — and what isn’t — may surprise you.
CBC’s Marketplace looked into the marijuana market ahead of the legalization of recreational pot, which is expected to be introduced through legislation in spring 2017 and to take effect in 2018.
When producers visited seven Toronto dispensaries and collected 12 of the most popular marijuana strains, laboratory test results showed average THC levels of around 20 per cent. THC is the active ingredient that provides pot’s high.
Some strains reached as high at 30 per cent THC, much higher than pot in the 1970s, when levels in Canada hovered between two to eight per cent, according to Jonathan Page, an adjunct professor of botany at the University of British Columbia.
Marketplace lab tests didn’t find cannabidiol (CBD) in the strains.
Study after study points to the attributes of combining THC and CBD. The science isn’t settled, but research suggests CBD can mitigate some of the negative effects that can happen with high-THC weed, including anxiety, paranoia, and psychosis.
