Can I Pass A Drug Test If I Drink Cranberry Juice?

No.

But you can pass a drug test if you don't do drugs.

: )

I wonder when people answer this question do they have real experience. FACT... This is my experience and is only with oxycontin 80 (OC 80 mg) used as much as 3x80 mg pills daily for 2 years) but I would think it works for all opiates because they are testing for the metabolite (morphine) which is the same for any opiate. I have passed every urine test for federal probation after snorting oxycontin, once as little as 12 hours before the test. I passed by taking 60-80, 500 mg cranberry pills (I have found the gel tabs are the best for quicker clean) with water and taken 8-10 times over the 12-18 hours (8-10 each time with a pint of water). The test has always been Immunoassay screening (cup stick) which generally has a limit of detection of around 300 ng/ml for opiate (morphine) which is the same for GC/MS analysis. Generally both tests have the same limits of detection, set the same only with opiates. For other drugs the GC/MS has lower limits of detection, so you could be negative with immunoassay screening but positive by by GC/MS analysis. I have passed 20-25 tests over a year and I used every day, without fail. I had a friend who was going to be tested by GC/MS analysis for work and had him do the same and he was negative for opiate after doing oxycontin 16 hours earlier. Do not know why it works and I again have only experience with opiates, OC 80 mg. Started doing it 24 hours before and through experience found that I can do it as little as 12 hours before! To be safe give yourself  24 hours and then work down. I tried to do only 8 hours and I was positive so I went back to 12+ hours. May work with heroin, just another opiate that metabolizes to morphine. They could test for the other heroin metabolite 6-monoacetylmorphine which is specific to heroin but have never seen it done.

The best way to be negative is just stop using before you ruin your life, that too is from experience!
