*Results of this study show that the exclusive use of e-cigarettes is more prevalent in higher-income and White smokers. Our data suggest that higher-income and White smokers may be more likely to use e-cigarettes as a means to quit combustible cigarettes compared with low-income and racial/ethnic minority smokers. These findings suggest that sociodemographic differences in e-cigarette uptake and use patterns may contribute to widening disparities in cigarette smoking. | *Results of this study show that the exclusive use of e-cigarettes is more prevalent in higher-income and White smokers.

=== [https://pubmed.ncbi.nlm.nih.gov/37866230/ An 8-year longitudinal study of long-term, continuous users of electronic cigarettes.] (2012-2016 to 2021 8 years is the average) === | |||
* Etter JF. ''Addictive Behaviors,'' 149, February 2024, 107891 | |||
* A rare look at long-term e-cigarette use (from 2012-2016 to 2021, averaging 8 years’ difference) and the shifts in use patterns: | |||
** Findings: Fewer people in 2021 (11%) than at baseline (33%) had smoked tobacco in the past 31 days. Participants switched from second-generation models at baseline (e.g. Ego) to box mods in 2021 (e.g. iStick), they used larger refill bottles, they used home-made e-liquids twice as often, they used tobacco flavours less often and the nicotine concentration in e-liquids decreased from 12 to 6 mg/L. | |||
* Given the concerns over the proliferation of products with high nicotine concentrations, it’s reassuring that people who use e-cigarettes long term tend to reduce their nicotine concentration over time. Likewise with indicators of dependence: | |||
** There was no change over time in the time to the first e-cigarette puff of the day, but an e-cigarette dependence score of 0-100 decreased from 75 to 60, the frequency and strength of urges to vape decreased (from 31% to 18% of the “strong” urges) and the proportion of people who said they would be likely to succeed if they tried to stop vaping increased. | |||
* Reasons for vaping also changed over time: | |||
** ''Compared to baseline, fewer people in 2021 reported vaping to cope with cravings or other smoking cessation symptoms, and fewer people reported vaping to quit smoking, to avoid relapse into smoking, or to reduce their tobacco consumption.'' | |||
* It makes sense that some of these motivations would decrease as people moved away from other tobacco products, but it is surprising to see that the reason of “avoiding relapse” was lower. If these reasons decreased, did other reasons increase? Yes, and they had to do with perceived addiction to e-cigarettes (from 49% to 62%), although endorsement of this was substantially lower than “vaping is less toxic than smoking tobacco” and simply “because I enjoy it” which nearly all participants endorsed. | |||
* Also notable is that at follow-up, 63% of participants said the flavors they used helped them quit or reduce their smoking, and 59% were afraid that they would start smoking again if they stopped using e-cigarettes. | |||
