See, that's a major problem I have with the one-size-fits-all, lumping of smoking into all the other harmful drugs logic.
No one ever ODed in a single sitting from smoking too much (long term effects notwithstanding). Smoking doesn't impair your ability to drive, or impair your judgement such that you would do things you normally wouldn't do. People don't ruin their lives, lose their jobs, or harm their families directly due to the effects of smoking. People don't go to cigar bars, then go home and beat their wives and kids because they've had too much to smoke.
I believe that that form of drug/alchohol addiction therapy is valid and highly successful, because it focuses strictly on the single drug, or combination of drug abuses, along with the psychological or emotional issues that may also exist. I would hazard a guess that it is overwhelmingly more successful for those drugs than when applied to smoking cessation.
Smoking is arguably the most tenacious addiction there is, not simply because of nicotine addiction, but because of all the other complex elements and dependancies involved in smoking. It deserves it's own category, and treatments tailored specifically to smoking cessation, not a generic "you're addicted to X, use this cure" approach.
That, at least, is my opinion on it.
