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."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '55 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': "Inclusion Criteria:\n\n* Have provided written informed consent\n* Be between the ages of 18 and 55\n* Be in good general health based on a physical examination, medical history, vital signs, and screening urine and blood tests\n* Test negative for drugs of abuse aside from cannabis (via urine sample) and alcohol (via breath sample) at the screening visit and upon arrival for each experimental session.\n* Not be pregnant or nursing (if female).
