Abuse Liability for Eight Electronic Nicotine Products

This will be a randomized, open-label, 8-way crossover, single-site study designed to evaluate elements of abuse liability (AL), including subjective effects and physiological measures (pharmacodynamics \[PD\]), and plasma nicotine uptake (pharmacokinetics \[PK\]) during and following ad libitum use of Electronic Nicotine Delivery System (ENDS) investigational products (IPs) in a confinement setting by generally healthy adult smokers of combustible cigarettes and dual users of cigarettes and ENDS products.
