Brief Summary:
A Randomized, Open Label, Parallel Group Study in Adult Smokers to Evaluate Changes in Biomarkers of Cigarette Smoke Exposure After Switching Either Exclusively or Partly to using JUUL Electronic Nicotine Delivery Systems With Two Different Nicotine Concentrations

Condition or disease Intervention/treatment Phase
Electronic Cigarette Use Cigarette Use, Electronic Tobacco Use Tobacco Smoking Other: Switch from UB of Combustible Cigarette to JUUL 5% Virginia Tobacco ENDS Other: Switch from UB of Combustible Cigarette to JUUL 3% Virginia Tobacco ENDS Other: Switch from UB of Combustible Cigarette to JUUL 5% Mint ENDS Other: Switch from UB of Combustible Cigarette to JUUL 3% Mint ENDS Other: Switch from UB of Combustible Cigarette to JUUL 5% Menthol ENDS Other: Switch from UB of Combustible Cigarette to JUUL 3% Menthol ENDS Other: Switch from UB of Combustible Cigarette to JUUL 5% Mango ENDS Other: Switch from UB of Combustible Cigarette to JUUL 3% Mango ENDS Other: Switch to Dual-use of JUUL 5% and UB of Combustible Cigarette Other: Tobacco/Nicotine Abstention Other: Usual Brand of cigarettes Not Applicable

Detailed Description:

Previous studies and data reported in the literature support that Electronic Nicotine Delivery Systems (ENDS) have less toxicant exposure. This study will serve as a clinical evaluation of exclusive-use of selected JUUL ENDS in 2 different nicotine concentrations (5%, 3%), with the purpose of gaining data to support the hypothesis that exclusive-use of JUUL ENDS over the course of 6 days will result in a significant reduction in toxicant exposure compared to combustible cigarettes.

This will be a randomized, open label, parallel group study in adult smokers to be conducted at up to 5 sites in the United States. Changes in Biomarkers of Exposure (BoEs) from baseline when using four JUUL ENDS with 2 different nicotine concentrations (5%, 3%) relative to Usual Brand (UB) of combustible cigarettes and a study group abstaining from any tobacco/nicotine product use will be assessed in this study. JUUL ENDS will be used either exclusively or partially (dual-use), with subjects in the dual-use group using both JUUL 5% ENDS (choice of Virginia Tobacco (VT), Mint, Menthol or Mango flavors) and UB of combustible cigarettes.
