Title: Nicotine Delivery From Novel Non-tobacco Electronic Systems (ENDS)
Brief Summary: This randomized pilot clinical trial studies nicotine delivery from novel non-tobacco electronic system (ENDS) in smokers. Studying the levels of nicotine delivered by various types and brands of ENDS to the bloodstream, and comparing this to the levels delivered from conventional cigarettes (the participant's own brand) may help provide information about the use of nicotine-containing products that may help inform/reform current tobacco policy, practice, and harm reduction approaches.
