Abstract

Introduction Many countries have now mandated warning labels on e-cigarette products. One example, the EU TPD health warning states, “This product contains nicotine which is a highly addictive substance. [It is not recommended for use by non-smokers]”. The impact of the EU TPD warning message on intentions to use, has not been explored within an EU population.

Aims Examine the effect of i) the TPD e-cigarette health warning and ii) an alternative relative risk message, on smokers' willingness to use, likelihood of purchase, and intention to use as a quit aid.

Methods Cross-sectional online study. Ninety-five smokers (55 males; 18–55 years old) were randomly allocated to one of three conditions and viewed ten individually presented e-cigarettes images with either no message, TPD message, or relative risk message. Participants rated i) willingness to use, and likelihood of: ii) purchase, iii) using in the next month, and iv) using in a quit attempt, before and after viewing the images.

Results For willingness to use and likelihood of purchase, ANCOVAs showed a significant main effect of Message Type (ps, <.05); ratings were lower in the TPD condition. Message type, however did not significantly change likelihood of using in the next month or using in a quit attempt.
