I'm sure you know this but addiction isn't just the physical dependence where your body requires the stuff to feel normal or 'well' during withdrawal. Even then the strength of dependence varies rather than exists as a binary thing. You might feel anxious without your daily doses of caffeine or sleep worse and get the sweats after discontinuing weed. In the worst cases, with alcohol especially, you might even die during abrupt withdrawal. But there is also the psychological component (habituation, compulsion, behaviour). For example you might still be left with the strong compulsion to smoke even if you satisfy nicotine addiction through other means or feel empty or distressed if your computer dies and you can't get online.
