A cross-sectional online survey of the impact of new tobacco health warnings in Colombia

This was an online cross-sectional survey that examined the rate of market saturation and the noticeability of new Colombian tobacco warnings among smokers over the implementation period in Colombia (Wave 1 – pre-implementation, Wave 2 – 12 months post-implementation). We also explored smokers’ negative affect towards warnings, cognitions related to smoking, knowledge regarding health risks of smoking, perceived severity and likelihood of harm from smoking and quit intentions across the survey waves and responses to each of the new warnings in terms of negative affect, believability, cognitions related to harm, avoidance, reactance and perceived message effectiveness.
