Clinical Trial Summary

In heavy marijuana smokers, opioid receptor blockade increases the subjective and cardiovascular effects of marijuana. The current study was designed to clarify opioid-cannabinoid interactions by assessing how naltrexone shifts the dose-response function for marijuana-elicited effects in heavy marijuana smokers. For this within-subject, double-blind study, a marijuana smoking procedure was designed to characterize a dose-response relationship for marijuana's subjective and cardiovascular effects under blinded conditions.
