Correcting Public Misperceptions About Very Low Nicotine Content Cigarettes

Study Summary

Tobacco use is the leading preventable cause of cancer and cancer deaths in the US. While most (69%) smokers want to quit, only 6% succeed in doing so each year. For many smokers, the addictiveness of nicotine makes quitting very difficult. To reduce cigarette smoking and resulting harms, FDA has announced a comprehensive approach to tobacco and nicotine regulation that includes moving toward a very low nicotine content (VLNC) standard for cigarettes. Greatly reduced nicotine levels would facilitate smoking cessation. However, the maximal success of the policy may require public understanding that, although these new cigarettes are less addictive, their high toxicity and carcinogenicity are unchanged. Yet, nearly half of adult smokers incorrectly think smoking VLNC cigarettes is less harmful than smoking current cigarettes (the VLNC misperception). Additionally, 24% of smokers said they would be less likely to quit if a VLNC regulation is enacted. Thus, the VLNC misperception may partially undermine a nicotine reduction policy. Although communication research suggests it is challenging to change people's incorrect understanding, new communication techniques may help reduce the VLNC misperception. In this randomized trial we will examine whether messages about the harm of VLNC cigarettes can reduce the VLNC misperception and increase intention to quit in a nicotine reduction scenario.

Primary Outcome

Measured by a 3 item scale. Very low nicotine content (VLNC) Misperception measured with 3 questions, the final VLNC misperception score is a mean of the response to the 3 questions, on a scale of 1 to 5, where 1 indicates a perception that VLNC are much more harmful than other cigarettes, and 5 indicates a perception that VLNC are much less harmful than other cigarettes, and 3 is a perception that VLNC are as harmful as other cigarettes.

Interventions

• BEHAVIORAL Emotion-based messages about the harm of VLNC
• BEHAVIORAL Continued-harm-framed messages about the harm of VLNC
• BEHAVIORAL Myth-refuting messages about the harm of VLNC
• BEHAVIORAL Control messages about littering
