Oh yeah I know how that works forsure, I just wanted to confirm the actual laws just for reference. Imagine a hardcore heroin addict or something smuggling heroin up his ass in portugal's big airport only to be x-rayed and then informed that its legal by the concerned, confused, security guard after a REALLY uncomfortable trip. Embarrassment? I'd think so haha, nobody wants to get caught smuggling something legal, you'd look like such a moron... plus security probably wouldn't know what to do with you. I'm sure its not a real common occurance.
