Restrictions of cigarette and e-cigarette flavor and filter ventilation on demand and substitution in the Experimental Tobacco Marketplace

Abstract

Significance

Tobacco product design features, including flavors and cigarette filter ventilation, are subject to regulation. This study examined the effects of cigarette and e-cigarette flavors on demand and substitution by preferred cigarette flavor and ventilation in the Experimental Tobacco Marketplace (ETM).

Methods

In a mixed between-group (usual cigarette flavor and ventilation)/within-subject design (policy conditions), individuals who use tobacco (n=176 cigarette (60.5 % female); n=91 multiple products (26.7 % female)) were recruited using Ipsos and InnovateMR, completed purchasing trials with increasing cigarette prices in the ETM. Participants were exposed to four conditions in a 2×2 factorial design with cigarette flavors restricted or unrestricted and e-cigarette flavors restricted or unrestricted.

Results

In individuals who exclusively smoke cigarettes: 1) Cigarette menthol restrictions decreased willingness to purchase cigarettes (OR: 0.001; 95 % CI: 0.00002, 0.015) for individuals that prefer menthol cigarettes and increased willingness to purchase NRT (OR: 4.02; 95 % CI: 1.47, 11.0), 2) cigarette menthol restrictions reduced demand for cigarettes in individuals who smoke menthol cigarettes (p<0.001), 3) e-cigarette flavor restrictions reduced the degree of e-cigarette substitution in individuals who smoke menthol cigarettes (p=0.028), and 4) preference for higher cigarette filter ventilation was associated with higher demand for cigarettes (p=0.003) and lowered substitution of smokeless tobacco products (p=0.028). In individuals who use multiple tobacco products, restrictions did not impact product purchasing.

Conclusion

Strategies to reduce flavored product sales and increase cessation resource accessibility may improve population health by reducing smoking and increasing NRT use in individuals who use menthol cigarettes.
