Harm Perceptions of Intermittent Tobacco Product Use Among U.S. Youth, 2016.

PURPOSE: We aimed to describe U.S. youth harm perceptions of intermittent tobacco use.

METHODS: Using data from the 2016 National Youth Tobacco Survey of U.S. students (grades 6-12; N = 20,675), we examined prevalence and correlates of all respondents' perceived harm of using four different tobacco products on "some days but not every day." Associations between current (past 30-day) use and harm perceptions were assessed using multivariable regression.

RESULTS: Perceiving that intermittent use causes "no" or "little" harm was 9.7% for cigarettes, 12.0% for smokeless tobacco, 18.7% for hookah, and 37.5% for e-cigarettes. Compared with those who reported "a lot" of harm, youth with lower harm perceptions were more likely to report current use.

CONCLUSIONS: One in ten youth perceived intermittent cigarette smoking as causing "little" or "no" harm; this perception was higher among current users. Efforts to educate youth about the risks of even intermittent tobacco product use could reduce misperceptions of harm.
