“…Our findings supported the evidence that a considerable proportion of dual users continue using e‐cigarettes after quitting smoking [2,12], but also showed that smokers using NRT and using e‐cigarettes had relatively high probabilities of transitioning to the abstinent ex‐smokers' group. Although recent ex‐smokers discontinue using NRT quicker than e‐cigarettes [45], our findings affirm that dual e‐cigarette use while smoking does not necessarily predispose to continued e‐cigarette use after quitting smoking. Generally, these transitions attest that alternative nicotine products might help smokers to quit, prevent relapse and eventually aid the transition to abstinence from nicotine.…”

Introduction and Aims. Smokers differ in how they smoke and how they stop smoking. Use of nicotine replacement therapy (NRT) and e-cigarettes further diversifies smokers. We aimed to identify and compare latent groups of past-year smokers and to describe longitudinal transitions between the identified groups. Design and Methods. Latent transition analysis of online UK past-year smokers' data (n = 2857) collected in June 2016 and followed-up in October 2017. Latent groups were identified based on participants' smoking, e-cigarette use, NRT use, urges to smoke and last quit attempt. Sociodemographic and smoking characteristics between the groups were compared using Pearson's χ 2 test and Cramer's V. Results. Four latent groups of smokers (heavy smokers, light smokers, smokers using NRT, smokers using e-cigarettes) and two recently quit smokers (abstinent ex-smokers, ex-smokers using e-cigarettes) were identified. Nearly half the participants (48.9%) were heavy or light smokers who did not use alternative nicotine products and largely had not tried quitting smoking. Latent groups were relatively stable and transitions to quitting smoking were more probable in groups of smokers using alternative nicotine products. Smokers using NRT transitioned mostly to abstinent ex-smokers, and smokers using e-cigarettes to exsmokers using e-cigarettes' groups (11.2% and 11.4%, respectively). The abstinent ex-smokers group grew the most at follow-up (+6.3%). Discussion and Conclusions. Nearly half of the participants continued smoking without having tried to reduce harm or quit. Of smokers who transitioned, the majority quit smoking and abstained from nicotine altogether. Use of alternative nicotine products alongside smoking was associated with higher probabilities of becoming an ex-smoker.

“…In relation to the sociodemographic associations, overall the results are in line with previously published work (Jackson, Hill, et al, 2019). Ever regular use of NNP was more prevalent in those from occupational grades ABC1 and use of alcohol to at least hazardous levels.…”

“…Similarly, NRT was associated with female sex, older compared with younger 16-24-year-old adults and at least hazardous drinking. E-cigarettes were most commonly ever regularly used by younger adults and there is decline in use by age, again this has been reported elsewhere (Jackson, Hill, et al, 2019).…”

Introduction: Up-to-date monitoring of non-combustible nicotine products (NNP) is important to assess their impact. To date, there is little evidence on the association between long-term regular use (defined here as one-year or more) of NNP and current smoking status. Aims/methods: The purpose of this study was to examine the prevalence, and sociodemographic, alcohol and smoking status correlates, of ever regular use of NNP in England in 2020.A cross sectional survey of adults in England between February and June 2020. Results: 8,486 adults were surveyed, 94.9% (8,055) were complete cases. The weighted prevalence of ever regular NNP use was 5.4% (n=436; 95%CI 5.0-6.0), of which 82% (n=360; 95%CI 78.7-85.8) was single, and 18% (n=79; 95%CI 14.8-22) multiple product use. Amongst ever regular NNP users, the prevalence of ever regular nicotine replacement therapies (NRT), e-cigarette and heated tobacco product use was 64.7% (95% CI 60.1-69), 43.4% (95%CI 38.8-48) and 2.5% (95% CI 1.4-4.5), respectively. In regression analysis, ever regular NNP use was independently associated with smoking status, being significantly higher among current (22.3%; Adjusted OR (aOR) 34.9, 95%CI 24.0-50.8) and ex-smokers (12.7%, aOR 19.8, 95%CI 11.1-14.4) than among never smokers (0.6%). More advantaged occupational grade (aOR, 1.27 95% CI 1.02-1.57) and at least hazardous alcohol use (aOR, 1.38 95%CI 1.06-1.78) were independently associated with greater prevalence of ever regular NNP use.Conclusions: Ever regularly using NNP was highest among smokers and ex-smokers and rare among never smokers. Among people who have ever regularly used NNP, NRT is the most popular.

“…Likewise, never use of alternative nicotine products does not mean smokers are not trying to stop smoking: they might instead choose behavioural and/or medicinal support, or no support at all. Nevertheless, smokers who use alternative nicotine products have been shown to be more motivated to stop and have higher chances to stop smoking [28]. Smokers who had and had not tried alternative nicotine products did not differ in gender, age or socioeconomic status, which confirms that e-cigarettes [29] and NRT [30] are equally used by smokers from different socioeconomic backgrounds.…”

Smokers who have not tried alternative nicotine products: a 2019 survey of adults in Great Britain

Aims: Switching from smoking to using nicotine replacement therapy (NRT), electronic cigarettes (e-cigarettes) or heated tobacco products can reduce tobacco-related health risks. However, not all smokers in Great Britain have tried these products. This study aimed to identify and describe smokers who have never tried alternative nicotine products. Methods: We analysed cross-sectional survey data of smokers (n = 1777) from a representative adult sample from Great Britain. The online survey was run in March 2019. The proportion of smokers who had never used alternative nicotine products was measured. A multivariate logistic regression assessed the association between never having used alternative nicotine products and sociodemographic and smoking characteristics and motivation to stop smoking. Results: One in four smokers (27.8%, 95% CI 25.8-29.9%) had never tried NRT, e-cigarettes or heated tobacco products. These smokers were more commonly from Black and Minority than White ethnic groups (AOR = 1.55; 95% CI 1.02-2.31), were more likely to smoke up to 10 versus more cigarettes per day (AOR = 1.52; 95% CI 1.14-2.03) and to report low versus moderate or high motivation to stop smoking (AOR = 1.79; 95% CI 1.20-2.74). Conclusion: Light smokers, those unmotivated to stop and smokers from Black and Minority ethnic groups are less likely to have ever tried alternative nicotine products. Different approaches are needed to facilitate harm reduction and smoking cessation among these groups of smokers.
