Thats easy, but please dont share this with anyone. They put it in their wallets. LE never checks your wallet no matter what! Sometimes if they don't have a wallet they coat the ampules with castor oil, swallow them and then later on wait till they get to the hotel and put a screen over the toilet seat. And since the ampules are greased with castor oil they pop right out on the first sitting. But dont worry, there will be more guys coming along soon who know the better secretes bro! No worries! so ssssshhhhhhhh!
