Many people with mental illness use cigarettes as a way to cope with their symptoms, despite the negative overall health impacts of smoking. E-cigarettes, which deliver nicotine without the additional carcinogens of cigarette smoke, have risen in popularity among people who believe they are a less-harmful option or may even help them quit. However, new research using a representative sample of U.S. adults finds that switching to e-cigarettes from traditional cigarettes did not prevent relapse to smoking within one year of quitting. Individuals who switched to any tobacco product, including e-cigarettes, were 8.5% more likely to relapse within one year compared to those who were entirely tobacco-free. To learn more, see the study in JAMA.
