Man, I lose everything when I roll... I've lost a wallet (complete with IDs and credit card), money, two cell phones, Calling cards... I've just learnt to leave all valuable things safe at my home when I take a pill.
Losing things when youa re stoned in universal. I have lost track of things lost all in all when I have been stoned. ALthough with time, it improves as you don't feel that stoned anymore.
