I have a drug test today. About three and a half weeks ago, I smoked some marijauna...first time in about four months. It was not a lot--I probably took no more than five or six puffs. I have not had any since. From yesterday afternoon until late evening, I drank water (about 50 oz. so far).

What are the chances of the marijauna showing?

And don't leave any comments about how I should never have smoked in the first place.
