The Effect of Prescription Medications in Marijuana Users

The Effect of Prescription Medications in Marijuana Users

A subset of heavy marijuana users have trouble quitting marijuana use and the number of those seeking treatment for problems related to marijuana is increasing. The purpose of this research study is to investigate whether dronabinol can reduce withdrawal effects associated with stopping marijuana use, if dronabinol can reduce the rewarding effects of smoked marijuana, and whether there are any cognitive performance deficits associated with dronabinol doses that produce such effects.
