This is a research study to find out if smoking cessation medications, either varenicline or nicotine replacement products (patches or lozenges), are effective when given to smokers, remotely, as a one-time sample.

Participants will either receive a sample of varenicline, nicotine patches and lozenges, or neither. This will be decided randomly. Participants have a 50%chance of receiving varenicline, a 25% chance of receiving nicotine products, and a 25% chance of receiving neither. If the participant is assigned to a group that receives free samples, they will be mailed to them free of charge. There is no requirement to use them, and it is completely up to the participants. There is also no requirement to quit in this study.

The study lasts for six months, and will involve six total surveys. In addition, we ask that participants complete daily diaries (about 1 minute each) for the first 4 weeks of the study. Both varenicline and nicotine replacement products are well-established medications that help smokers quit.

This is a research study to examine if and how patterns of use change over time among three different groups of tobacco users: 1) adults who exclusively smoke combustible cigarettes, 2) adults who exclusive use e-cigarettes, and 3) adults who use both. 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 smoking/e-cigarette 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 your 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, 3) Follow-Up Diaries in each of the 7 days leading up to each monthly follow-up survey, and 4) Submission of Breath Samples (13 total).
