The present study compared the disposition and metabolism of the recreational drug (±) 3,4-methylenedioxymethamphetamine (MDMA, “ecstasy”) in squirrel monkeys and humans because the squirrel monkey has been extensively studied for MDMA neurotoxicity. A newly developed liquid chromatography-mass spectrometric procedure for simultaneous measurement of MDMA, 3,4-dihydroxymethamphetamine,...

This study examines the plasma pharmacokinetics of 3,4-methylenedioxymethamphetamine (MDMA) and metabolites 4-hydroxy-3-methoxymethamphetamine (HMMA), 3,4-methylenedioxyamphetamine (MDA), and 4-hydroxy-3-methoxyamphetamine (HMA) in young adults for up to 143 hours after drug administration. Seventeen female and male participants (black, white, and Hispanic) received placebo, low (1.0 mg/kg),...

A single 90-mg dose of the cannabinoid CB1 receptor antagonist rimonabant attenuates effects of smoked cannabis in humans. The objective of this study is to evaluate whether repeated daily 40-mg doses of rimonabant can attenuate effects of smoked cannabis to the same extent as a single higher (90 mg) dose. Forty-two male volunteers received one of three oral drug regimens in a randomized,...

Animal studies suggest that cannabinoid CB1 receptors play a role in regulating blood pressure (BP). In human studies, activation of CB1 receptors by cannabis or its active ingredient, Delta9-tetrahydrocannabinol (THC), has modest and inconsistent effects on BP. We evaluated this phenomenon in 63 male cannabis smokers (mean [SD] age 27.7 +/- 5.4 years, 70% African American, 10.3 +/- 5.9 years...

Rapid blood collection, a paced smoking protocol and timely collection of physiologic and behavioral measures were used to characterize the absorption phase of marijuana smoking. Six healthy males smoked a single marijuana cigarette (placebo, 1.75%, or 3.55% delta-9-tetrahydrocannabinol) in a double-blind, randomized, Latin square study design. Rapid blood sampling with a continuous withdrawal...
