Yes I'm very much sure they are allowed to. Well atleast as long as they have reasonable doubt. The only thing I think they need a warrent for is to search your house. And I dont think they are allowed to smash your shit cause they need it for evidence. Also how much Bud did they find?

Plead guilty in court. Depending on the amount the price can range from 200-To in the thousands. Im guessing you had about 3 grams or so. That can go up to i think a max fine of 200 dollares for that amount. Like I said It depends On how much you had. What you had on you. The state you live in I'm guessing you live in the states. And the judge you get. Inless the cop just took your shit and smoked it.
