Communicating About Nicotine Reduction in Cigarettes

The goal of this clinical trial is to learn how a messaging campaign about reduced nicotine cigarettes and policy, combined with the use of very low nicotine cigarettes (VLNCs), affects smoking behavior and attitudes among adult smokers. The study also aims to assess the efficacy of the messages in different populations, including smokers with past-month serious psychological distress (SPD), low socioeconomic status (SES), and those in neither category. The primary hypothesis is: exposure to messages in combination with VLNC use will lead to less cigarettes use compared to VLNCs without messages. Researchers will compare: The effects of receiving VLNCs with messages (treatment group) to receiving VLNCs without messages (control group). Participants will: Complete a baseline survey and be randomly assigned to one of two groups: treatment (VLNCs + messages) or control (VLNCs only). Attend weekly study visits for surveys, breath samples, and receive supply of VLNCs , either with or without the messaging campaign. Complete brief daily surveys through text messages.
