Weighted analyses using a subset of current adult smokers (n=10 565) estimated the prevalence of NAS use (vs all other brands) and examined associations between NAS use and sociodemographics, tobacco/substance use, tobacco harm perceptions, quit intentions, quit attempts and mental/behavioural health.Results Overall, 2.3% of adult smokers (920 000 people in the USA) reported NAS as their usual brand. Nearly 64% of NAS smokers inaccurately believed that their brand is less harmful than other brands compared to 8.3% of smokers of other brands, after controlling for potential confounders (aOR 22.82). Younger age (18–34 vs 35+; aOR 1.54), frequent thinking about tobacco harms (aOR 1.84), past 30-day alcohol use (aOR 1.57), past 30-day marijuana use (aOR 1.87) and sexual orientation (lesbian, gay, bisexual, ‘other’ or ‘questioning’ vs heterosexual; aOR 2.07) were also associated with increased odds of smoking NAS.Conclusions The majority of NAS smokers inaccurately believes that their cigarettes are less harmful than other brands. Given the brand's rapid growth and its more common use in vulnerable groups (eg, young adults, lesbian, gay, bisexual, ‘other’ or ‘questioning’ adults), corrective messaging and enforcement action are necessary to correct harm misperceptions of NAS cigarettes.
