If you HONESTLY dont want to get caught, but you MUST do it.... get some good tape, shave your gooch (in between balls n ass) and tape it there. Or get a condom, shove ur weed in there, and shove it up your ass (obviously take a shit before doing so) if its that big of a deal to have weed. Nasty, but if you can deal, its better than sitting in a prison cause the way you were patted down it was felt in your crotch.
