What's in a Name? Three-Quarters of Marijuana Strains Tested in New Study Had the Same Amount of THC and CBD

Knowing how much THC is in a given strain might not actually indicate how high you'll get.

A group of researchers from the University of British Columbia recently published a study comparing the chemical makeup of 33 different cannabis strains. Specifically, they focused on how much THC (the primary psychoactive compound) and CBD (a non-psycho active compound that is popular as medication) was found in each strain. Turns out, the levels detected were pretty well the same in three quarters of the strains tested, according to researchers.

"The main THC and CBD composition was not different among 24 of the 33 strains we tested," Susan Murch - one of the study's authors - told Motherboard. "However all of the strains have different names from different producers, so for 73 percent of strains, the name does not really mean that they are different based only on the THC and CBD."

As each of the strains evaluated were purported to contain "quite different" levels of CBD and THC, it makes it difficult for consumers to know what they're getting based on those figures alone.

But while most strains have comparable levels of THC and CBD, that doesn't mean they'll affect the consumer in the exact same way. Researchers noted that those affects may actually come down the various other cannabinoids (the name given to the chemicals found in cannabis) that are present in a strain.

So, different strains probably will affect you differently—even if they all have the same level of THC.


These veteran curlers hope to bring some new life to the sport by combining it with cannabis. Last October, Grant Nicholson and Ted Ratcliffe pitched a novel idea to their curling club's executives: the Wiarton & District Curling Club should host what may be Canada's first official 'bongspiel' - a pun on bonspiel, the official name for curling tournaments. The event, which is essentially a bring-your-own-weed curling tournament, proved far more popular than the club executives expected, selling out completely in the first 24 hours.
