“JUUL vs. Mod E-cigarette Study”
Some smokers who try e-cigarettes transition completely from cigarettes to e-cigarettes, but others continue to use both products, or abandon e-cigarettes and return completely to cigarettes. One factor that likely impacts these tobacco use patterns is the e-cigarette device used. The majority of e-cigarettes purchased today are one of two "types:" customizable tanks or pods. These e-cigarette types differ from each other in critical ways, like nicotine delivery and sensory characteristics, that are likely to impact use by influencing the relative reinforcement value of the product. The present study will be a randomized trial investigating the impact of e-cigarette device type on reinforcement value and use among current smokers. Current smokers (n=100) will be randomly assigned to either a control group that does not receive an e-cigarette or one of two e-cigarette types: a customizable tank, or a pod. The impact of device type on relative reinforcement value will be assessed using a choice task. Participants will also take home their assigned e-cigarette for a three-week sampling period. Primary outcomes include relative reinforcement value (choices to smoke in the lab-based choice task), cigarette smoking behavior (cigarettes smoked per day during sampling), and uptake (e-cigarette puffing episodes per day during sampling).
Pod System E-cig
Participants assigned to this intervention will try to pod system e-cigarette in the lab and receive a pod system e-cigarette to use for a three week sampling period.
Customizable Tank E-cig
Participants assigned to this intervention will try to customizable tank system e-cigarette in the lab and receive a customizable tank system e-cigarette to use for a three week
Participants will not receive any e-cigarette
