Correct. "Not doing $X anymore" doesn't mean you aren't an addict. "Being able to turn on/turn off doing $X" means you aren't an addict. If you haven't had a drink in years, but having a single one means that you now cannot do without the bottle, you're still an addict.
I've always said that there's no such thing as an ex-smoker; they're smokers who haven't smoked in a long time.
