This report examines the characteristics of adult smokers who use e-cigarettes during their attempt to quit smoking. It highlights differences between dual users and those who only smoke cigarettes, and discusses how frequent e-cigarette use may affect long-term cessation success.
The findings suggest that while baseline e-cigarette use does not significantly impact overall quitting success, higher frequency of use among recent users might hinder long-term abstinence, possibly due to increased nicotine dependence.
