Arms & Interventions
Single arm design
On four separate occasions, participants will come to the research center and be asked to use a nicotine pouch or smokeless tobacco provided by the study team two separate times. The nicotine pouches or smokeless tobacco contain different amounts of nicotine. Participants will not know the concentration of nicotine in the nicotine pouch, but they will know the concentration and brand of the smokeless tobacco (it will be their usual brand). All participants will complete all four study conditions.
Intervention: oral nicotine pouch - 2 mg (Other)

Outcomes
Primary Outcomes
Change in Plasma nicotine concentration
Time Frame: Baseline to the end of the session, approximately 4 hours
Blood will be taken multiple times in each session to assess the extent to which product use changes plasma nicotine levels compared to baseline
Secondary Outcomes
No secondary outcomes reported
