Vaping harms awareness messaging: exploring young South Australians' responses to vaping prevention campaign materials.

Nicotine vaping products (NVPs) pose health risks associated with nicotine dependence and increased likelihood of tobacco consumption. Despite having a secondary role in smoking cessation, recreational NVP use is increasing among younger people. Vaping prevention campaigns aim to influence views on the health risks of vaping. This study examined perceptions of Australian and international vaping prevention campaigns among 27 young South Australians aged 16-26 years who do and do not use NVPs, to inform targeting and framing of vaping risk messaging. Participants viewed example materials from three vaping prevention campaigns: 'Epidemic', 'Do you know what you're vaping' and 'Unveil what you inhale'. Focus groups and interviews assessed whether materials were easily understood, appropriate, relevant, credible and effective in health communication. Participants indicated that all campaigns would influence their thoughts and actions related to vaping. The 'Do you know what you're vaping' campaign prompted thoughts about uncertainty about individual health risks, though participants did not indicate that this was enough to motivate vaping cessation. Participants considered the 'Unveil' campaign effective, with those who did not vape indicating they would click through to access resources, and those who did vape responding well to the 'challenge' aspect of the messaging. The 'Epidemic' campaign fear appeal did not clearly prompt change in vaping views or behaviours. Campaigns using a challenge approach may generate conversation about vaping harms, while fear appeals can be dismissed by younger audiences. Evidence-based short messages and the presentation of multiple versions of content were considered effective approaches.
