Ya shit like that used to happen to me..but Im 4 years into it now, and you get used to it alot, Ive talked to cops baked off my ass and they didnt even know(my friends got pulled over for burnt out tail lights and shit, like one time we got pulled over and we had like 7 grams of shrooms on us and another quarter of weed). And either the cop couldnt tell or he was being cool about it..lol. But anyways you do get used it so you can function normally.
