Regional French evolution of tobacco and e-cigarette experimentation and use among adolescents aged 15-16 years: A cross-sectional observational study conducted in the Loire department from 2018 to 2020.

BACKGROUND

We assessed/compared the evolution of tobacco and e-cigarette experimentation and use among French adolescents of the Loire department aged 15-16 years.

METHODS

A descriptive, cross-sectional/observational study conducted in 2018-2020 among 7,950 Year 11 pupils attending 27 public secondary schools of the Loire department, France.

RESULTS

From 2018 to 2020, 66.18% of adolescents were "non-vapers and non-smokers", 19.76% were "vapers and smokers", 7.90% were "non-vapers and smokers" and 6.15% were "vapers and non-smokers". E-cigarette experimentation was more prevalent than tobacco experimentation (44.92% vs 41.67%), and daily vaping was less prevalent than daily smoking (5.40% vs 10.24%). More boys than girls were daily vapers or daily smokers. A decrease was observed in tobacco experimentation (from 41.22% in 2018 to 39.73% in 2020) and e-cigarette experimentation (from 50.28% in 2018 to 41.25% in 2020). Current vaping remained stable, with an increase in daily vaping. French adolescent vapers frequently use e-liquids with little or no nicotine or with fruit or sweet flavours.

CONCLUSIONS

Adolescents used e-cigarettes mainly for experimental and/or recreational purposes, with no intention of progression to daily smoking. Although the design of this study is not longitudinal and caution must be exercised, from our cross-sectional observational study data, it appears that the proportion of "non-vapers and non-smokers" tended to increase. "Smokers" tended to progress to the dual use of vaping and smoked tobacco, with the likely intention to reduce or quit smoking.
