It's the resistance or lack thereof that separate the addicts from the abusers.
By definition, chemical addictions cannot be cured, only managed.
A chemical addiction occurs when a certain chemical in one's brain is destroyed by the drug, and then replaced by the drug itself. Smokers have a certain, necessary drug missing from the brain, that was destroyed by smoking. The only way they can replace that chemical is by smoking (or a patch, etc). Same thing for alchohol, cocaine, heroin, and every chemical addiction.
Certain people can manage their addiction so it doesn't affect their lives in ways that it shows, but it always affects them. It is something that they have to fight every day for the rest of their lives. This is not psychology, it's chemistry.
