The latest analysis from the University of Mississippi's Potency Monitoring Project found THC at its highest level in marijuana since testing began in the 1970s.

"Marijuana potency has grown steeply over the past decade, with serious implications in particular for young people, who may be not only at increased risk for psychological conditions, cognitive deficits, and respiratory problems, but are also at significantly higher risk for developing dependency on other drugs, such as cocaine and heroin, than are non-smokers."

The Potency Monitoring Project has been analyzing marijuana samples since 1975. In their most recent quarterly report, the researchers documented THC levels as high as 37.2 percent, with average levels at about 9.6 percent. Of special concern among substance abuse specialists is the fact that increased THC levels increase the probability that users will become addicted.
