Interest in "organic," "natural," and "additive-free" cigarettes after hearing about toxic chemicals in cigarette smoke

Experimental data analysis was conducted in 2016-2017. Smokers indicated greater expected interest in "organic," "natural," and "additive-free" cigarettes than "ultra-light" cigarettes (all p
