Differences in cigarette smoking quit attempts and cessation between adults who did and did not take up nicotine vaping: Findings from the ITC four country smoking and vaping surveys.

Introduction:
This text summarizes a longitudinal study examining the relationship between the initiation and frequency of nicotine vaping product (NVP) use and smoking cessation among daily smokers in four countries. The study aims to determine if NVP use is associated with increased quit attempts and abstinence from smoking.

Key Points:

* The study followed a cohort of daily smokers who were not using NVPs at baseline and collected data over two follow-up periods.
* The study found that daily NVP use was associated with increased quit attempts and abstinence from smoking, while non-daily NVP use was not.
* The study also found that continued regular daily vaping was a key predictor of successful smoking cessation.
* The study controlled for various factors, including age, sex, country of residence, education, income, cigarette dependence, plans to quit smoking, quit attempt prior to baseline, time-in-sample, wave of recruitment, and NRT use at follow-up.
* The study's sample size was large, with 3516 unique individuals and 4612 observations.
* The study's design was longitudinal, with data collected at three time points over two follow-up periods.
* The study's outcome measures included quit attempts and smoking abstinence.

Main Message:
The main message of this study is that daily NVP use is associated with increased quit attempts and abstinence from smoking among daily smokers. This suggests that NVPs may be a useful tool for smoking cessation, particularly for those who use them daily. However, non-daily NVP use was not associated with increased quit attempts or abstinence, highlighting the importance of regular use for smoking cessation. Overall, this study provides valuable insights into the relationship between NVP use and smoking cessation, highlighting the potential benefits of NVPs for those looking to quit smoking.
