What this research studies
You would join a tobacco-quit program where adults who smoke cigarettes are followed through a planned quit attempt, with extra enrollment of people who also use cannabis. Researchers track cigarette use, cannabis use, and e-cigarette use over time using surveys and biochemical measures. The study compares quit outcomes for cigarette-only smokers versus those who co-use cannabis or vaped nicotine products. The goal is to see how cannabis use changes during quitting and whether it makes stopping tobacco harder.
Who could benefit from this research
Good fit: Adults aged 21 and older who currently smoke cigarettes and are willing to try to quit, including those who also use cannabis or e-cigarettes.
Not a fit: People who do not smoke cigarettes, are under 21, or are not planning to attempt tobacco cessation would not be eligible and are unlikely to benefit.
Why it matters
Potential benefit: If successful, this work could help clinicians tailor quitting programs for people who also use cannabis.
How similar studies have performed: Earlier studies have shown mixed results but suggest cannabis co-use may hinder quitting, and this prospective trial builds on that prior work by oversampling co-users.
