Washington, D.C.Today, the Office of National Drug Control Policy (ONDCP) released the latest analysis from the University of Mississippi’s Potency Monitoring Project, which revealed levels of THC – the psychoactive ingredient in marijuana – have reached the highest-ever levels since scientific analysis of the drug began in the late 1970s. According to the latest data on marijuana samples analyzed to date, the average amount of THC in seized samples has reached a new high of 10.1%. This compares to an average of just under 4% reported in 1983 and represents more than a doubling in the potency of the drug since that time.
