Opioid Antagonism Enhances Marijuana's Effects In Heavy Marijuana Smokers

Effect None
Trial Design Double blind
Trial Length 1-7 Days
Number of Subjects 29
Sex Both Genders
Age Range 18-29
Notes for this study:
In a study assessing the interactions of naltrexone and marijuana, when comparing the marijuana only group against the double placebo group in heavy smokers, marijuana alone (800mg of a 3.27% THC cigarette) was insufficient to impair psychomotor performance, short term memory, or attention on computerized testing (DRT, DAT, DSST).

Peripheral effects of marijuana (heart rate) also appeared to be enhanced alongside the enhanced neurological high in these heavy users.
