The Impact of Including Cessation Resource Information on Health Warnings on Standardized Tobacco Packaging on Awareness and Use: A Longitudinal Online Survey in the United Kingdom.

The findings support the inclusion of a stop-smoking website on warnings as awareness among smokers increased and citing warnings as a source of information about a stop-smoking website was associated with having visited a stop-smoking website. We also explored whether the stop-smoking website on warnings on RYO packs, which is larger than on cigarette packs as a function of the larger size of RYO packs, would have any impact on awareness of this information. That exclusive RYO smokers were more likely than exclusive cigarette smokers to notice a stop-smoking website on warnings suggests that this information should be more prominent.
