Impact of Brief Nicotine Messaging on Nicotine-Related Beliefs in a U.S. Sample.

The current study pilot tested the effect of a single, brief exposure to nicotine education messages on beliefs about nicotine, nicotine-replacement therapy (NRT), E-cigarettes, and cigarettes with reduced nicotine content (RNC). Five hundred and twenty-one U.S. adults (aged ≥18 years) completed a 15-minute survey on Amazon Mechanical Turk in 2018. After completing items on sociodemographics, literacy, and cancer risk behaviors, participants were randomized in a 2:1:1 ratio to 1 of 3 conditions: nicotine education (n=263), sun safety education (attention control, n=128), or no message control (n=130). All participants completed items regarding nicotine, NRT, E-cigarette, and RNC cigarette beliefs, as well as norms about nicotine use, behavioral control regarding cigarette/tobacco use, and intention to use cigarettes, NRT, E-cigarettes, and RNC cigarettes in the next 12 months. Analyses were conducted in 2019. Following exposure, nicotine education participants reported fewer false beliefs about nicotine (p<0.001), NRT (p<0.001), E-cigarettes (p<0.05), and RNC cigarettes (p<0.05) compared with the control conditions. Nicotine messaging doubled the probability of a correct response (false, 78.3% vs 36.8%) to nicotine is a cause of cancer and dramatically reduced the probability of responding don't know to this item (5.3% vs 26.0%). There was no impact of the intervention on beliefs about other substances within cigarette, norms, or behavioral intentions. Findings from the current study support the hypothesis that a brief nicotine messaging intervention-similar to the messages likely to be seen on warning labels or in media campaigns-is likely to correct misperceptions of nicotine, NRT, E-cigarettes, and RNC cigarettes.
