On my way back from Mexico with my wife i put 100 cuban cigars in my luggage. I got to customs and they asked if i had anything to declare. I said, "yes I have 100 cuban cigars in my bag". The woman rolled her eyes and said "cuban cigars are illegal in the country sir". I said "well its cuban seed tobacco but rolled in mexico" (a lie) and she said "please move along you're holding up the line". So they aren't really looking for OTC prohormones or cuban cigars. They're looking for heroin, cocaine, marijuana, etc. I always have a much harder time getting my heroin into the country.
