Study Summary

The cannabinoid delta 9-tetrahydrocannabinol (THC) is the primary psychoactive component of marijuana. THC is believed to be a significant factor in the addictive potential associated with marijuana use. In addition, attenuated levels of endogenous endocannabinoids have been found in alcohol-dependent individuals as compared to social drinkers, suggesting that changes in the sensitivity of the endogenous endocannabinoid system play a role in the transition from recreational drug use to substance use disorders. Thus, pharmacotherapies that target the cannabinoid system may be effective strategies for reducing marijuana use and dependence. Recent preclinical data demonstrate that the neurosteroid pregnenolone (PREG) inhibits THC activation of cannabinoid receptors and decreases symptoms of marijuana intoxication. In addition, other studies show that PREG inhibits drug-seeking behavior. This pilot study will provide important preliminary data on the effect of an acute dose of PREG on cue-related craving in individuals with cannabis use disorder.

Primary Outcome

Change in craving from post medication administration to post active cue. Scale of 1-7 with 7 meaning the craving is most severe.
