Listen man! If you're burning fat, then the metabolites are going into your system and the water you're drinking is helping your system flush them out. How? Well if you aren't hydrated, you sweat until you pass out... so if you're drinking water, you can keep sweating and running for much longer and not stop which means less traces of weed in you. If you aren't doing exercise and drinking water, then yes it is only good strictly for dilution.

Bottom line is: YOU'RE GOOD TO GO! I just passed a drug test without anything (look at my post in the forums "passing w/o subbing or detox") and I only spent 2 weeks naturally detoxing. I only took 1 test the day before my test and since I came out negative with the first void I decided to reschedule for the same day and get it over with. Oh! and my roommate pretty much hot boxed my apartment 2 days before AND was smoking around me when I came out of my room the morning of the test.

GO GET THAT JOB
