Outcome Measures
Primary Outcomes (1)
Plasma Nicotine
Change in plasma nicotine level
Blood will be taken 4 times in each session: baseline, 5 minutes after the start of a 10-puff product use, and then before and after an approximately 1-hour ad lib use period.
Study Arms (6)
Own brand cigarette first, then ENDS with protonated nicotine, then ENDS with unprotonated nicotine
EXPERIMENTALIn each of the 3 sessions, participants will be instructed to take one puff of the tobacco product (cigarette or Subox Mini C ENDS with 18 mg nicotine) every 30 seconds for 5 minutes followed by a 2nd blood draw (if staffing allows). Next, participants will be given 90 minutes to use ad lib, i.e., as much as desired.
