Harm perceptions of vaping nicotine relative to cigarette smoking among sexual and gender minority young adults.

Abstract

To address gaps in existing research, the current study used a mixed-methods approach to describe, contextualise and understand harm perceptions of vaping nicotine relative to cigarette smoking and associations with nicotine and tobacco (NT) use among young adults who identify their genders and sexualities in ways that classify them as sexual and gender minorities (SGM). Results are based on cross-sectional surveys and online qualitative interviews with 98 SGM young adults (18-25 years old) in California's San Francisco Bay Area who currently or formerly used combustible tobacco. We generated a measure assessing participants' relative harm perceptions of e-cigarette use versus cigarette smoking and identified those who perceived cigarette smoking as more harmful than e-cigarette use compared to those who perceived it to be equally or less harmful. We found that relative harm perceptions of cigarette smoking versus e-cigarette use are likely related to much uncertainty and confusion about the harms of e-cigarette use. Moreover, findings illustrate that public health messages regarding the risks of e-cigarette use may have unintended consequences of increasing cigarette use to replace e-cigarette use for some SGM young adults, a practice that is incongruent with scientific evidence demonstrating that cigarettes and other combustible tobacco products are riskier than e-cigarettes and other forms of NT use. Results suggest the need for evidence-based, clear, and direct messaging about the relative harms of cigarettes versus e-cigarettes to reduce NT-related inequities in SGM populations.
