People generally don't go to living facilities for cigarettes, nor sell themselves or everything they own or end up on the street jacking off strangers because of cigarettes though.

Something can be more addictive while causing less withdrawal symptoms.

I don't disagree with you, but the context was telling people to "just quit smoking," which is pretty silly advice because of how addictive it is. Those same people probably wouldn't seriously say, "just quit heroin."
