fyi, there is a difference between 'problematic consumption' and 'addiction', and there are separate tests for each. of course they're correlated and there is a path that leads from one to the other, but there are important differences - especially since addiction is pretty much considered to be sticky.

so once you are addicted, you'll stay that way, even if your consumption ceases completely (at which point you're an addict who doesn't exhibit problematic consumption). that's why clean alcoholics (or any clean drug addicts) are usually advised to stay teetotal indefinitely: they'll usually bounce back to their old patterns very quickly if they have a fallback.
