This is a research study to understand patterns of nicotine pouch use over time among three separate groups of people who: 1) co-use nicotine pouches and cigarettes, 2) co-use nicotine pouches and conventional smokeless tobacco (including chewing tobacco, dip, moist snuff, or snus), or 3) exclusively use nicotine pouches. This is a naturalistic survey study; there is nothing required or requested of participants other than to complete our surveys. Participants do not need to quit or reduce their pouch/smoking/smokeless tobacco product use if they do not want to. They do not need to travel for this study; it is completely remote, and they can participate from their home.
Participation in the study will take place over a period of 12 months in the form of: 1) Monthly Surveys (13 total), 2) Daily Diaries for the first 90 days, and 3) Follow-Up Diaries in each of the 7 days leading up to each monthly follow-up survey.
