Potency Monitoring Program

Marijuana stored at the University of Mississippi

By analyzing marijuana samples confiscated by law enforcement agencies and submitted to the UM marijuana project, the project has historically assisted a number of federal agencies in planning drug control and public health strategies. These “potency monitoring samples” were tested for their cannabinoid levels and the results were compiled into a database made available to the National Institute on Drug Abuse (NIDA) and DEA, as well as the White House Office of National Drug Control Policy (ONDCP).

The relevance of these long-term studies can be seen in the fact that within only a 10-year period (1998-2008), the THC potency of confiscated marijuana increased by 103%.

However, due to a lack of funding, this crucial program has ceased analyzing samples, although agencies continue to submit samples to UM for testing. UM hopes to reinstate the program in time to prevent a significant lapse in the long-term data set, which is now approaching 80,000 samples.
