Dependence motives of young adult users of electronic nicotine delivery systems.

Introduction:
This text is a summary of a scientific study examining the relationship between electronic nicotine delivery systems (ENDS) dependence motives, ENDS use, and attempts to quit in young adult ENDS-only and combustible cigarette dual users. The study also explores whether sex moderates the relationships between motives and use or quit attempt. The key points and main message of the study are summarized below.

Key Points:

* The study used an online survey to collect data from a sample of 304 young adults who were regular ENDS users.
* The study measured ENDS use behaviors and dependence motives using the Wisconsin Inventory for Smoking Dependence Motives (WISDM).
* The study found that tolerance and loss of control were uniquely associated with ENDS use behaviors, although the effects for loss of control were counter-intuitive.
* Craving was positively associated with lifetime quit attempt among males but not females.
* The study controlled for past 30-day cigarette use per day and race in all analyses.
* The study used backward-stepwise models to regress ENDS use behaviors or lifetime quit attempt onto dependence motives and their interactions with sex.
* The study found that certain motives were either more salient or non-significant predictors of ENDS use for men or women.

Main Message:
The study provides valuable insights into the relationship between ENDS dependence motives and use behaviors or attempts to quit. Understanding these relationships can inform preventive interventions against increased or continued ENDS use. The study also highlights the importance of considering sex differences in ENDS use and dependence motives, which can help tailor interventions to specific populations. Overall, the study underscores the need for further research to better understand ENDS use and dependence and to develop effective prevention and intervention strategies.
