Addicted to smoking or addicted to nicotine? A focus group study on perceptions of nicotine and addiction among US adult current smokers, former smokers, non-smokers and dual users of cigarettes and e-cigarettes.

Perceptions of nicotine and addiction among non-smokers, former smokers, exclusive smokers and dual users of cigarettes and e-cigarettes vary based on smoking status, but there is a common tendency to believe that nicotine is addictive, that addiction results from more than just nicotine, and that very low nicotine cigarettes will not necessarily reduce the addictiveness of cigarettes.
