Workplace smoke-free policies that allow heated tobacco products and electronic cigarettes use are associated with use of both these products and conventional tobacco smoking: the 2018 JASTIS study.

Workplaces that allow HTP/e-cigarette use indoors were associated with higher rate for HTP and e-cigarette users, and for combustible cigarette smokers. National legislation banning tobacco should be enforced and also cover HTPs and e-cigarettes in order to avoid renormalisation of smoking and nicotine addiction.
