More often than not, there isn't. Your brain chemistry is just messed up and dependent on the drug. Ask any ex-addict about their cravings.
The ones who manage to make it out, usually have something to live for (and the will to live for it), but a lot of people have no money, no job, no career, no family, no spouse, no kids, and no good memories of life, and even if they did, there's no guarantee they'll beat the substance. Sadly for these people, it's very likely they won't see a way out of addiction.
The consensus is that "hitting rock bottom" is the only way to help an addict. But many hit rock bottom and never get up again, or don't have anything to climb for.
