Hey everyone i really need some advice, i got caught on November 20 09 with weed on me at school, i got charged with possession and yesterday i met my P.O. for the first time. i signed a contract thats placing me on probation for 6 months, and basically i cant do shit. The thing is i have some bud left that i want to smoke and then im going to stop. Yesterday my .P.O. gave me my first drug test and i passed, he told me that he will visit me randomly and give me tests whenever he feels like it. He doesent look like a bullshitter, i just really want to smoke badly and past my next drug test, if i drink a fuck load of water will i pass it? i cant go to supermarkets or stores to buy any detoxs cuz im lock down. What should i do?
