Using Semi-Verified Methods

  1. Also called flushing, this method remains one of the easiest, cheapest, and most successful ways to get a false negative on a pee test. Pee tests do not measure the amount of drugs in urine; they measure the amount of metabolites in the urine. Drugs are ingested and then come out of the system as metabolites. [1] Drinking more water will help your body produce metabolites that aren't tainted by drugs.
    • Urinalysis checks for 31 different metabolites caused by marijuana, 4 caused by cocaine , 3 caused by opiates, 1 caused by Phencyclidine, and 5 caused by amphetamines.
    • Be careful not to over-hydrate. Although rare, it is possible to drink too much water and damage your internal organs, enough so to become fatal. [2] This is called water intoxication.
  2. If you notice your pee becoming excessively watery — a clear tip-off for some analyses — try taking the vitamins B-2 or B-12 . These can also be found in B-Complex multivitamins, and turn the color of your urine yellow. Take about 50 to 100 milligrams.

  3. [3] Diuretics help your body rid itself of water and sodium. [4] Coffee, diet pills, and certain prescription drugs are also diuretics, but they're not as effective as Midol at ridding your body of the water that contains those telling metabolites. It may sound weird to have Midol if you're a dude, but don't worry, you'll thank Midol after your drug test comes back negative.
  4. How you pee into the urinalysis cup matters. Try peeing a little bit into the toilet, and then direct your stream into the cup when you're nearing the end of your stream. Pee near the end of the stream is supposed to contain fewer metabolites than pee at the beginning.
    • Try also to pee several times in the morning before taking the drug test. Your pee will contain more metabolites if you haven't already gone to the bathroom before you take the test. Be smart and chug some water first thing when you wake up the day of the test.
  5. One study suggested that taking 4 aspirin 4 to 6 hours before the screening can mess with the test, EMIT. [5] Don't worry, 4 aspirin in a single serving will leave you fine, albeit a little light-headed.
  6. There's no evidence that these products work. On top of this, they're expensive, and many of the ingredients are simple diuretics, which you can purchase or make for far less cash. It's pretty safe also to assume that drug testing companies are trying just as fast to come up with ways to detect these substances as manufacturers are coming up with ways to invent them. If you can, stay away.

Doing a Healthy Flush

  1. You'll need a full range of vitamins and healthy drinks to protect from hyperhydration. [6] This method takes at least a week, but it's healthier than overloading your system with water, which can flush out important vitamins, nutrients, and electrolytes. To do a healthy flush, you'll need to constantly replace what is being flushed out. Stock up on the following:
    • Multi-vitamins
    • Sports drinks
    • Fresh fruits and veggies
    • Tea (green detox tea
    • Other diuretics (cranberry or apple juice, coffee, etc.)
  2. Drink 20 to 40 ounces of sports drink per day to restore your electrolytes and keep you hydrated . Drink roughly 1 gallon (3.8 L) of water to flush your body of toxins. Drink the tea and other diuretics throughout the day as well. Do not drink more than 2 gallons (7.6 L) total of fluids per day.
  3. Replenish your body by taking a multivitamin either once or twice a day, as directed on the packaging.
  4. Exercise every day. Build up as much of a sweat as possible, since sweating is a way to detox your body. The kidneys and the bladder can only filter so much in such a time. Sweating helps the body excrete waste through your pores, as well as your bladder.
  5. Your body will need all the nutrients it can get. Eat plenty of fruits, vegetables, legumes, and lean proteins the week before your drug test.
  6. If you feel sick, you could be taking in too much water in too short a time. Your health is more important than passing the drug test, so don't overdo it.

Method 3 of 3:

Trying Unverified Home Remedies

  1. Drink cranberry juice or take cranberry supplements. Cranberry is a natural diuretic, meaning it will help your body flush itself of water and sodium, though not at the rate that Midol might. Although there is some doubt about cranberry's effectiveness for regular drug users, it really can't hurt if you use it responsibly and in combination with other methods.
  2. Many drug users report successfully passing an EMIT test after taking zinc sulfate. The zinc is reputed to bond to the metabolites and guide them into the fecal tract instead of the urinary tract.
    • Take about 250 mg of zinc sulfate the night before your test. Avoid eating too many solids. Then, the morning of your test, take the same dose of zinc sulfates. Do not take any more than this if you choose to use zinc. Over-medicating with zinc can lead to harmful mineral deficiencies and should be avoided.
  3. Some people choose to use Niacin, or vitamin B3, in the hopes that it will help them pass their drug test. Niacin has not been proven effective at masking drugs in the urinalysis. [7] [8] Moreover, it's possible to experience very adverse side-effects with over-medication. [9] If you do choose to use Niacin to try to cover up drugs in your system, be careful. It's probably safer to try to use another product or method.
  4. This is a last resort, but if you can't try any of the above methods, you can try to spike the urinalysis. Bleach, detergent, or blood is rumored to be capable of throwing off the results of the test in order to buy you more time.
    • If you have long fingernails, try hiding a small amount of bleached laundry detergent crystals underneath them. Then, when it comes time to take the test, add the detergent crystals to the pee sample and be sure to mix well. This may buy you enough time to take the test again another time when you're more prepared.

      • Drug screening is more sophisticated every day, but by being hip to stuff that works you'll have the underground info as to what works, and there will be zero drugs or metabolites left in your system to show a positive result.

      • If you're ballsy enough to sneak in soap or bleach you may as well just get synthetic human urine and use the substitution method. Some products come with a bladder bag and a tube to simulate normal urination (field kit for example) and others have a great reputation of success and can be reheated repeatedly for practice runs. With this method there are 2 important things to make sure of. One is that the temperature is correct on the sample. Many of the synthetic products come with a chemical heating pad. The second thing is making sure the product is legitimate. You can use home drug test and ph test kits from your local pharmacy to assure the validity of your "sample". Pass the temp test (94-100 degrees) and make sure the product is good and you're golden! Pun intended.
        Thanks

      • Check the Internet. It's littered with products that guarantee to help you pass a drug test. Merchants claim to offer a 500% money back guarantee if the product sucks, and it usually does. They fail to mention that after you buy and use their stuff and you get a positive test result, you won't be around to collect the refund.
        Thanks

      Tips from our Readers

      The advice in this section is based on the lived experiences of wikiHow readers like you. If you have a helpful tip you’d like to share on wikiHow, please submit it in the field below.
      • Ask a friend with clean urine to provide a sample for you in a condom or container shortly before your test. Keep it tucked against your body to stay warm, then use a needle to puncture the condom and pour the clean urine into the collection cup.
      • While commercial masking products often don't work, simple baking soda may help. Mix 1 tablespoon of baking soda per 50 lbs of body weight into water and drink about 2 hours before the test. This can cause diarrhea but may mask drug metabolites.
      • Try taking zinc supplements — zinc is thought to help move drug metabolites out of the urinary tract. However, only take about 250 mg daily for 1-2 days before the test. Taking too much zinc can lead to dangerous mineral imbalances.
      • Exercise vigorously in the days leading up to the test to sweat out toxins. Pair exercise with drinking extra fluids to flush your system. Pay attention to signs of dehydration and stop exercising if you feel unwell.
      • Consider using an at-home drug test first to see if you will pass before going to the official test. That way, you can avoid over-diluting your sample if you test negative at home.

      About This Article

      Article Summary X

      Your best chance of passing a urine drug test is to drink lots of water before your test to flush out the metabolites caused by drugs that are in your system. To prevent your urine from looking too clear when you take the test, take between 50 and 100 mg of B2 or B12 vitamins — they’ll turn your urine yellow. You can also try taking 4 aspirin a couple hours before your test to interfere with the test results. For more techniques you might try, like exercising and eating healthy foods, read on!
