What this research studies

If you are an adult with a mental health condition who smokes, you may be offered free e-cigarettes and supplies to try replacing most or all of your cigarettes. Participants are randomly assigned to receive either e-cigarette provision alone or e-cigarettes plus extra behavioral counseling to support switching. Researchers will track how much participants smoke and vape and will collect biomarker tests that measure exposure to tobacco carcinogens. Follow-up visits will measure changes over time and help determine which approach helps people reduce harm most effectively.

Who could benefit from this research

Good fit: Adults (21 and older) with a diagnosed mental illness who currently smoke cigarettes and are willing to try e-cigarettes are the best candidates to participate.

Not a fit: People who are not current smokers, are under 21, are unwilling to try e-cigarettes, or who prefer to pursue complete nicotine abstinence rather than switching are unlikely to benefit from this program.

Why it matters

Potential benefit: If successful, this approach could reduce exposure to cigarette carcinogens and lower smoking-related health risks for people with mental illness.

How similar studies have performed: Earlier pilot studies and one randomized trial in smokers with mental illness showed meaningful reductions in cigarette use and some switching to e-cigarettes, though switching rates were modest.
