ALL YOU DO IS THIS:
You wear 3 layers of pants.... athletic shorts with pockets, put stash in that pocket double bagged, whatever, than wear boxers on top of that, than your jeans.... so if for some random reason they do in fact decide to search you when they check your pockets all they feel is your jeans, when they check your belt/waist, they see boxers... and your good to go, ive personally gone through and extra security check (SSSS) and had no problems, smooth as butter. And another thing, there arnt ever really drug dogs at an airport they're all bomb dogs, #1 you cant really carry that much bud in your carry on...#2 they arnt worried about drugs going through the airport for that reason so 99% of the time its going to be a bomb dog not a drug dog. I would only even consider it a sliiiight concern if flying internationally or through NYC or Los Angeles.... but even than its not ANYthing to worry about b/c chacnes are you will never see one while your there
