What is the face of new nicotine users? 2012-2018 e-cigarettes and tobacco use among young students in Italy (2020)

Background: With increased use of electronic-nicotine delivery devices (e-cigarettes) and non-cigarettes tobacco products (heated tobacco products, shisha, moist snuff/snus) among adolescents, the percentage of Italian students who use nicotine products is at its highest level of the past ten years, even though prevention and anti-smoking policies have produced tangible results in decreasing tobacco smoking prevalence. This cross-sectional study examined trends in exclusive and dual smoking, identified new poly-consumption patterns and profiled old and new nicotine users.
Methods: We used the annual cross-sectional ESPAD® Italia survey which sampled students (aged 15-19), currently used for surveillance and monitoring of at risk population, between 2012 and 2018 (N = 170,974) to describe Italian trends in exclusive cigarette, exclusive vaping, and dual cigarette and vaping use. For the 2018 sample, patterns of poly-consumption were described, and a multinomial logistic regression (N = 15,732) estimated characteristics associated with exclusive and dual cigarette and vaping use.
Results: The lifetime prevalence of cigarette smokers slightly decreased from 60.9% in 2012 to 56.9% in 2018, whereas the proportion of vaping users substantially increased from 32.9% in 2013 to 52.0% in 2018. Combining cigarette and vaping use, these trends result in an increase in the lifetime prevalence of any use from 60.8% in 2013 to 66.2% in 2018. Three out of every 10 minors have experienced smoking and/or vaping, and younger students were more prone to be dual users. Overall, current vapers were generally less prone to risky behaviours.
Conclusion: In contrast to a slight decrease in cigarette smoking, the prevalence of Italian students approaching old and/or new smoking habits in their lifetime is substantially increasing. The popularity of alternative nicotine-based products, particularly e-cigarettes, has increased among teenagers, resulting in a summation of usage patterns rather than a compensation, and attracting a novel slice of young users. The lack of regulation within current drug policy to limit the access to such licit psychoactive substance use, is urgently needed to avoid a future nicotine addicted population.
Highlights:
• Evidences confirm a decreasing trend in cigarette smoking prevalence among youth.
• The spread of new nicotine-delivery devices has changed the panorama of youth habits.
• A debate is ongoing on whether these devices are a gateway to nicotine addiction.
• Such devices may attract towards nicotine dependence new slices of young population.
