Misperceptions about the effectiveness of cutting down and low-rate daily smoking for reducing the risk of tobacco-caused harm

Reducing the amount smoked per day, or smoking at a low rate, confers limited protection from smoking harms. We aimed to quantify the prevalence of misperceptions about cutting down and low-rate smoking among Australian adults who smoke. Cross-sectional online survey in April/May 2022 (N=2,740). Participants were asked whether they agreed (misperception) or disagreed that "Reducing the number of cigarettes smoked per day is an effective way to reduce the risk of experiencing the health harms of smoking". They were also asked whether the statement "Smoking 1 cigarette per day is about 1/20th as dangerous as smoking a pack of 20 cigarettes per day" sounded about right (misperception) or if it was less dangerous (misperception) or more dangerous than that. The misperception that reducing the number of cigarettes smoked is an effective way to reduce risk was held by 72.0% of people who smoke overall, but was more common among those who smoked
