You probably don't.
The basic thought here is undoubtedly something along the lines of "My urine is being tested. Therefore, I want to get the concentration of drugs in my urine down to some level that is within the margin of error of the test; one way to do that is to dilute it, so Lasix - a drug that increases urine production - will help."
The problem is that drug testers are not utter morons, and the resulting pale color of the diluted urine is more or less a dead giveaway that you're trying to hide something, which is just going to get you retested, possibly using a different methodology.
You MIGHT be able to use it to flush out your system if you know far enough in advance of the test... for example, it might help you to pass a test given when you apply for a job, because you have some control over when you apply. It's pretty much useless for random testing once you've GOT the job, though... you'll just need to stay clean.
The only way to pass a drug test is to stop using drugs. Simple as that.
Using a Bic razor is the only way to pass a hair drug test.
You pass the test by not using drugs.
No. Depending on the drug it stays in your hair and fat cells. If you want to pass a drug test quit using.
yes
stop using drugs
Stop using Methadone.

Not in a million years freak!!
No, if it doesn't kill you it will make you sick and could burn the soft tissue in your mouth. Stop using if you want to pass a drug test.
Usually it takes months....
Will you pass a swab drug test if you passed a urine drug test on the same day?
