Comparing cigarette and e-cigarette dependence and predicting frequency of smoking and e-cigarette use in dual-users of cigarettes and e-cigarettes

Introduction: This study examines the dependence and predictive frequency of cigarette and e-cigarette use among dual-users of both products. The study utilizes the Patient-Reported Outcomes Measurement Information System (PROMIS) and PROMIS-E to measure the dependence on each product and evaluates how these dependencies relate to the frequency of using each product. The key points and main message of the study are summarized below.

Key Points:

* The study found that dual-users reported stronger dependence on cigarettes than on e-cigarettes.
* The PROMIS and PROMIS-E were scalar measurement invariant, indicating that mean-level comparisons of cigarette and e-cigarette dependence were justified.
* Cigarette and e-cigarette dependence were related, yet distinct constructs.
* Stronger cigarette dependence predicted more frequent past-month smoking and less frequent past-month vaping.
* Stronger e-cigarette dependence predicted more frequent past-month vaping and less frequent smoking.
* The study highlights the importance of assessing dependence on both cigarettes and e-cigarettes when examining dual-use.

Main Message: The study demonstrates that dual-users of cigarettes and e-cigarettes can distinguish between dependence on each product, and that the level of dependence on each product is associated with the frequency of using that product. These findings suggest that reducing dependence on both cigarettes and e-cigarettes is important for decreasing the frequency of use and promoting cessation. As an expert in regulatory matters, it is crucial to consider the impact of regulations on nicotine dependence and use patterns across different tobacco products. This study highlights the importance of assessing dependence on both cigarettes and e-cigarettes when developing and implementing regulations to reduce tobacco use and nicotine dependence.
