My question involves criminal law for the state of MN. When i was 17 i got cought drinking. Like 2 months later i was cought with small amount so i was put on probation. My first meeting i took a ua and i passed. Now i have a diffarent po and she has never given me or other friends a piss test. I have just turned 18 so all my charges were when i was 17. If i fail my next ua what will happen to me?
