| ===2022: [https://pubmed.ncbi.nlm.nih.gov/35913015/ Prospective Association between E-cigarette Use Frequency Patterns and Cigarette Smoking Abstinence among Adult Cigarette Smokers in the United States]===
| |
| *In a US cohort of adult smokers, longitudinal patterns of vaping frequency appear to predict smoking abstinence, even after accounting for several sources of systematic error. Consistent daily vaping is associated with increased chances of cigarette smoking abstinence, while consistent non-daily vaping is associated with decreased chances of smoking abstinence.

| |
| *Nearly two thirds of current vapers are ex-smokers (64.6%), and the proportion continues to grow, while the proportion who also smoke (known as dual users) has fallen to 30.5% in 2021.
| |
| *Fewer than 1% of never smokers are current vapers (amounting to 4.9% of vapers).
| |
| *As in previous years the main reason given by ex-smokers for vaping is to help them quit (36%) then to prevent relapse (20%).
| |
| *The main reason given by current smokers for vaping is to cut down (26%) then to help them quit (17%) and to prevent relapse (14%).
| |
| *Nearly a third of smokers incorrectly believe vaping is more or equally as harmful as smoking (32% compared to 34% in 2020).

| |
| *Qualitative research suggests e-cigarettes can meet many of the needs of ex-smokers by substituting physical, psychological, social, cultural and identity-related aspects of tobacco addiction.
| |
| *According to a time-series analysis of data from the Smoking Toolkit study, in which repeated cross-sectional surveys are conducted with a representative sample of households in England, increasing prevalence of e-cigarette use in current smokers was predictive of higher success rates of quit attempts.
| |
| *Most participants were self-reported long-term abstinent smokers (86.3%).
| |
| *Those who start on a low self-reported nicotine e-liquid concentration (strength) will be more likely to relapse to tobacco smoking than those starting on a higher nicotine e-liquid, after controlling for cigarettes per day (CPD) before cessation.
| |
| *Results suggest a change in flavor choices over the course of vaping initiation and uptake. There was a reduction in the proportion of people using a tobacco flavor, and increase in the proportion using a fruit/sweet/food flavor, from initial to current flavor choice
| |
| *According to the 2017 ASH-A survey, among current users, fruit flavors were the most popular.
