Trial Design Double blind
Trial Length 1-6 months
Number of Subjects 19
Gender Both Genders
Age Range 18-29
Notes for this study:
Inhalation of marijuana (800mg of 5.5% or 6.2% THC) in a placebo controlled study every other day for 3-6 weeks in regular marijuana users, assessing a variety of puff counts to assess dose-dependent effects, noted that subjective highs and stimulation were not dose-related although craving for marijuana was reduced with more puffs.

Relative to placebo there were reductions in psychomotor performance (DSST) and immediate but not delayed recall (DRT), with other cognitive parameters not affected.
