I've only known a few dope addicts that don't smoke and even when they quit, it's very common In NA that they offer ya coffee and cigarettes. Most junk addicts that quit Dope continue smoking tobacco too. At least at the beginning, only a very small percentage are able to quit everything at the same time. They have to replace it with something though, whether it's gym, painting, singing, running, etc. Idk but u can't get rid of an addiction without having to replace it with something else.As a Heroin addict, the comment "cigarettes are more addictive than Heroin" never made any sense at all to me.
Every addict is a different unique world on its own too, so this topic is a very complex thing to analyze and we could spend months talking about it without reaching a consensus lol cheers buddy
