I'd be interested to know how variable it is from person to person. I had long-term (>1y) treatment with reasonably high doses of fairly mild opiates (tramadol/codeine) twice, as well long-term treatment with benzodiazepines, and each time I literally just stopped - no tapering or dose reduction, no withdrawal or ill effects (aside from the original pain returning), and no cravings to seek more

Cigarettes, on the other hand, I've smoked a couple of times (1 or 2 cigarettes each time), and every time there's been this thought at the back of my head "I should get some cigarettes" for most of the following day. It's obviously not addiction and easy enough to ignore, but it's definitely a noticeable effect. Interestingly two lengthy (4 hour plus) shisha sessions didn't have the same effect (was a little light-headed and felt like I'd had about 50 cups of coffee, but no effects or cravings the following day).
