Back in the ’60s, ’70s and ’80s, weed was nothing much more than some funky grass that made you feel chill, silly and hungry. But today, the US government’s Office of National Drug Control Policy has announced that the average percentage of THC, the psychoactive ingredient, in the currently available marijuana has risen to 9.6-percent, up from 1983’s report of just under 4-percent.

The study was done by the University of Mississippi’s Potency Monitoring Project (how do we join?), which tested 62,797 cannabis samples, 1,302 hashish samples, and 468 hash oil samples, confiscated by law enforcement. “The increases in marijuana potency are of concern since they increase the likelihood of acute toxicity, including mental impairment,” said Dr. Nora Volkow, Director of the National Institute on Drug Abuse.

Increased mental impairment a concern? Well, our only concern is getting our hands on some of that bud.
