烟鬼

Chainsmoker / Smoker Ghost. It refers to someone addicted to smoking or having heavy-smoking habits, equivalent to the English expression like “smoker”, even more emphasizing on a person who smokes excessively. Can also imply mystery, like 'a puff of smoke' or a ghostly appearance. Might also suggest rebellion and non-conformity as some people might consider smoking cool or naughty.
