Joints/blunts in the car or while outside moving and shit, and if you are in a house or something chiller, use your bowl. You cannot eat a bowl but it is wicked easy to get rid of a joint or blunt.
I knew a kid who got caught in a school zone with separetly bagged 1/8ths and he got community service and probation I think. Just puts it all in perspective, they would likely arrest you though.
