A coworker used the following story, apt since he lives in a state bordering another country: "Let's say I go to Canada for a day trip, Montreal perhaps. I speak enough French to get around but it's not so good after an evening of drinking and socializing. The next morning, I wake up with a powerful hangover headache. A pharmacy is nearby, but my head is pounding too hard to read the labels so I go to the pharmacist. In broken French, I ask him for some Tylenol. He asks me 'what kind?' 'Just one,' I reply. He sells me a small bottle with a Tylenol label; I pop a couple and put the rest in my bag. After I return home--declaring 'nothing' at the border, of course, since I forgot about the bottle of medicine--I find the bottle and notice the word 'Codeine' on the label. Canada sells 'Tylenol One,' a compound with this addition. I'm technically guilty of felony drug trafficking of a schedule 2 narcotic into the United States as well as felony concealment (drugs). Are you certain you've never done something seemingly innocent that's actually a serious crime?"
