There could be a variety of reasons why artists smoke cigarettes. Some people might start smoking as a way to fit in with other smokers in the music industry, or because they think it makes them look cool. Others might start smoking as a way to cope with the stress of their career, or because they're trying to self-medicate for anxiety or other mental health issues. Additionally, some artists may simply be attracted to the addictive and pleasurable effects of cigarettes, and enjoy having something to do with their hands while they are performing or recording.
