My friend said he did it with a baggie tucked behind his balls. I guess whitie-tighty undies would help there. Then he said he did it another time with a sharpie marker. He opened the pen/marker up, cut the ink pad inside and cleaned it out and put a blunt in there. But neither of those methods are going to stop a drug sniffing canine. I've never done either, and but I have had a couple of people (tourist types) ask me where a Head shop is located. I would just point them in the direction of a head shop/bong shop. Seems like good common sense advice, in search of weed, find the stoners at the bong shop for instance, or the surf shop, skate shop, there's even a hemp shop in vancouver that sells hemp products. I would rather risk asking someone who works at one of those shops where the weed is, or rather if they 'knew a pretty lady named mary jane?', rather than risk taking any on a plane ever. But I don't know ur areas laws so I would follow them.
