One of my siblings relayed a story of their college days when someone they knew was busted by the police for selling pot.  Turns out later the police had to drop all the charges when the testing of the pot showed they were selling random crushed up leaves instead, apparently not illegal.  I wonder just how many of their customers bragged about how stoned they got off it.  I also wonder if any of their customers came back demanding refunds?  Or were they just too embarrassed that they were had?
