Smokers' perception of the comparative health risks of cigarettes, e-cigarettes and heated tobacco products: a survey among the German population.

Abstract

Tobacco cigarettes, e-cigarettes and heated tobacco products can pose different health risks (harm continuum). As current tobacco smokers could benefit from switching to less harmful products, we aimed to assess current smokers' perceived comparative health risks of these three products and to explore associations between risk perceptions and specific user characteristics. We analysed data from 11 waves (2019-2021; N=5657 current tobacco smokers) of a representative, cross-sectional household survey conducted in Germany. Associations were assessed with multivariable logistic regression models. 55.2% of smokers (95%CI=53.8-56.5%) ranked cigarettes as the most harmful product. 36.1% of smokers (95%CI=34.8-37.3%) perceived e-cigarettes and 33.8% (95%CI=32.5-35.0%) heated tobacco products as more harmful than cigarettes. Misperceptions that e-cigarettes or heated tobacco products are more harmful to health than cigarettes increased over the 3-year study period and were more common among those with lower educational attainment. Only half of current tobacco smokers in Germany perceive the comparative health risks of cigarettes adequately and such misperceptions have increased recently. As current smokers could benefit most from switching to less harmful products, educational campaigns are needed to inform this group about the health risks of tobacco smoking and the comparative health risks of the various nicotine and tobacco products along the harm continuum.
