Cessation outcomes in adult dual users of e-cigarettes and cigarettes: the Population assessment of Tobacco and health cohort study, USa, 2013-2016.

Introduction:
This text summarizes a study on the transitions of adult dual e-cigarette/cigarette users in the United States in relation to nicotine dependence symptoms, interest in quitting, and history of cardiovascular disease. The study uses data from the Population assessment of Tobacco and health (PaTh) study Waves 1 and 3 (2013-2016) to examine the tobacco use transitions of adults who were dual users at Wave 1.

Key Points:

* The study followed 1,870 adult dual users for two years and found that 25.7% were still dual users, 12.1% reported no past-month tobacco use, 7.0% were exclusive e-cigarette users, and 55.2% were exclusive cigarette users.
* Greater nicotine dependence severity was associated with decreased risk of no past-month tobacco use.
* Interest in quitting and cardiovascular disease factors were not associated with no past-month tobacco or e-cigarette mono-use.
* The study highlights the need for other cessation resources to support the needs of cigarette smokers who use e-cigarettes, particularly those at risk of continuing cigarette smoking or those with smoking-related illness.

Main Message:
The study found that adult dual users who are nicotine dependent are less likely to transition to cessation. This suggests that other cessation resources may be necessary to support the needs of cigarette smokers who use e-cigarettes, particularly those at risk of continuing cigarette smoking or those with smoking-related illness. The findings also emphasize the importance of examining tobacco use transitions in vulnerable subpopulations, such as those with cardiovascular disease, to inform tobacco control policies and interventions.
