Yes you wont. But you will talk with your p.o and they will help determine how much is in your system and if it#039;s residual or high potency. They can determine if you#039;ve recently used or not. If you haven#039;t, you#039;re at least going to get talked to. If you have, you#039;re s.o.l, dear.
First, if you're SURE you're going to fail it, then be TOTALLY honest with the officer, believe me it will pay off in the long run. They want to believe that people can change and honesty is the first best step in their mind. If you think there is a chance that you can pass it then I suggest drinking tons of water, just don't over do it cuz water can end up poisoning you by removing essential nutrients in your body.
