And, in case anyone missed it, there are things that are OTC here in Canada that are Schedule III in the US. My personal favourite is what is variously called AC&C or 222, a tablet containing 375mg ASA, 15mg caffeine and 8mg codeine phosphate — perhaps the best safe combination for occasional migraine-type headaches. (You need to register and sign for them in Quebec, a measure that's intended to prevent bulk purchases, but you're on your own say-so elsewhere; you merely need to ask at the pharmacy counter and they'll give you the safety drill if you're a first-timer.) Useful damned things to have around if you're susceptible. But totally illegal to have without a scrip in the States.
