Behavioral Pharmacology of Cannabis and Nicotine

2019-10-18 11:21:47 | BioPortfolio


This study will evaluate the individual and interactive pharmacokinetic and pharmacodynamic effects of smoked cannabis and nicotine.


The proposed study will be conducted at the Johns Hopkins Behavioral Pharmacology Research Unit (BPRU). All participants will be healthy adult volunteers who are regular nicotine/tobacco users, and have prior experience with cannabis use. Participants will complete seven outpatient experimental test sessions (completed in a randomized order), under double-blind conditions in which participants will first self-administer smoked cannabis (either active or placebo), followed by nicotine (via a tobacco cigarette or an e-cigarette); there will also be one condition in which participants smoke active cannabis alone (without subsequent nicotine use). Nicotine self-administration will occur in an ad libitum fashion for 5 hours. Nicotine products will be the individual participant's preferred brand of cigarettes or the commercial pod-style e-cigarette the JUUL (pods will contain either 3% or 5% nicotine pods). Active cannabis will contain 10 mg tetrahydrocannabinol (THC) while placebo will contain 0 mg THC. During the ad libitum nicotine/tobacco-use period, various puffing behaviors (e.g., puff volume, puff duration, puff number, inter-puff-interval) will be measured using specialized equipment. Acute subjective effects of cannabis/nicotine, cannabis/nicotine withdrawal symptoms, craving, vital signs, and cognitive/psychomotor performance will also be assessed throughout the experimental sessions.
