associations between nicotine vaping uptake and cigarette smoking cessation vary by smokers’ plans to quit: longitudinal findings from the International Tobacco Control Four Country Smoking and Vaping Surveys.

Introduction: This text summarizes a research study on the relationship between nicotine vaping uptake and cigarette smoking cessation among smokers with different plans to quit. The study uses longitudinal data from the International Tobacco Control Four Country Smoking and Vaping Surveys in the United States, Canada, England, and australia. The key points of the study are outlined below.

Key Points:

* The study included daily cigarette smokers who had not vaped in the past 6 months and participated in two or more consecutive waves of the ITC Four Country Smoking and Vaping Surveys.
* The study assessed plans to quit cigarette smoking, descriptive characteristics, vaping uptake, cigarette smoking cessation, and planning to quit cigarette smoking at follow-up, all stratified by plans to quit smoking at baseline.
* Generalized estimating equations were used to evaluate whether inter-wave vaping uptake was associated with smoking cessation at follow-up and with planning to quit at follow-up, each stratified by plans to quit smoking at baseline.
* The study found that daily vaping uptake was associated with higher odds of smoking cessation among smokers not initially planning to quit within 6 months, compared to no vaping.
* among smokers planning to quit, smoking cessation rates were similar between those who did and did not take up daily vaping.
* Daily vaping uptake was associated with planning to quit smoking at follow-up among those initially not planning to quit.
* The study suggests that excluding smokers not planning to quit from studies on vaping and smoking cessation may underestimate the potential benefit of daily vaping for daily smokers.

Main Message: The study highlights the importance of considering smokers' plans to quit when evaluating the relationship between nicotine vaping uptake and cigarette smoking cessation. The findings suggest that daily vaping uptake is strongly associated with cigarette smoking cessation among smokers with no initial plans to quit smoking. Therefore, excluding smokers not planning to quit from studies on vaping and smoking cessation may underestimate the potential benefit of daily vaping for daily smokers. The results of this study have important implications for tobacco control policies and regulations.
