*Findings: Between 2012 and 2019 there was a marked decline in past-30-day cigarette smoking and a surge in use of e-cigarettes. Different products were associated with differing levels of nicotine dependence, with cigarettes characterised by highest dependence (strong craving 42%, wanting to use within 30 minutes 17% among exclusive users in 2019) and e-cigarettes in otherwise tobacco-naïve students by low dependence (16% and 9% in 2019). The overall 34% increase in population use of nicotine products between 2012 and 2019 (from 23.2% to 31.2%) was not accompanied by an equivalent increase in overall population burden of dependence (percentage reporting craving 10.9% [95% CI 9.8-12.2%] in 2012 and 9.5% [7.5-12.0%] in 2019; wanting to use within 30 minutes 4.7% [4.0-5.5%] in 2012, 5.4% [4.0-7.2%] in 2019). | |||
*Conclusions: Among US high school students, increases in the prevalence of nicotine product use from 2012 to 2019 do not appear to have been accompanied by a similar increase in the population burden of nicotine dependence. This may be at least partly attributable to a shift in the most common product of choice from cigarettes (on which users are most dependent) to e-cigarettes (on which users are least dependent). | |||
