Environmental Smoking Restrictions and Light Cigarette Adoption Among Chinese Urban Smokers.

Light cigarette adoption involves complex psychological and behavioral processes with many underlying factors. While numerous studies have shown that environmental restrictions on smoking are associated with higher probability of smoking cessation, it is also possible that some smokers may switch from regular to light cigarettes due to environmental pressures. The current study evaluates whether smoking restrictions in households, workplaces, and public places were respectively associated with light cigarette adoption. A cross-sectional multistage sampling process was used to recruit participants and collect data about demographics and smoking characteristics and environmental restriction variables. Multiple logistic models were employed to examine the association between environmental smoking restrictions and light cigarette adoption. Of 4735 respondents, 1592 (30.3 %) were current smokers, and 69.7 % (N = 1141) of the smokers were identified as light cigarette adopters. In a multivariate model, smoking restrictions in households, workplaces, and public places were significantly associated with higher light cigarette adoption. Under environmental smoking restrictions, which pose unique challenges to tobacco control efforts, light cigarette adoption may increase. The study findings are essential for health policy makers in designing and implementing targeted smoking cessation interventions and health education programs.
