How to beat a drug test

Looks like a bottle of eye drops in your pee can save you and neutralize any THC, so there is nothing to detect.

Here’s a new article from WebMD

Drug-Test Cheats Try New Tricks on Labs
Experts Say Internet and Household Products Bring New Challenges to Drug Testing

Vinegar. Lemon juice. Drain-cleaning products. At least one of these items is probably in your kitchen. And any of them can be used to beat a drug test.

For about 20 years, people have been using a long list of very ordinary household items to confuse prospective employers and drug labs hoping to catch them in the act of using or abusing illegal drugs.

Add to the list laundry detergent, baking soda, and ordinary salt.

“Does it work? Yes, it does,” says Amitava Dasgupta, PhD, a professor of pathology and drug testing expert from the University of Texas-Houston Medical Center. “It’s a cat and mouse game.”

Employer drug testing became popular in the late 1980s after President Ronald Reagan instituted drug testing as a requirement for federal jobs. Lots of private companies followed suit, and today thousands run drug tests on people applying for jobs.

Many schools also conduct drug tests on students trying to join sports teams, or, more controversially, sometimes conduct tests on a random basis.

Many household items change urine’s pH, or acidity, when they’re added to it; most of the time that renders a sample useless for testing. But these are not the cheating methods that worry testers like Dasgupta.

That’s because labs can easily tell when urine has been adulterated with household items. Usually they just disqualify the applicant without even bothering to test for specific drugs.

Online Test-Cheating Industry

That’s what happens with most of the so-called “detoxifying” drinks that can be found online. Most of the drinks are simply loaded with caffeine and come with directions to drink lots and lots of water. That dilutes the urine, which can sully a drug test.

But testers are prepared for dilution, Dasgupta says. Any sample below a certain concentration is automatically rejected, regardless of whether it has evidence of illegal drugs in it.

“There is no magic formulation which can take drugs out of your body,” Dasgupta says.

Chris Faught, who heads chemical testing at the University of Arkansas for Medical Sciences, says his lab routinely sees dilution as a strategy to fool drug tests in the emergency room. “We get results that are simply suppressed so there’s obviously an interfering substance. The old classic way is to drink lots and lots of water,” he tells WebMD.

But the gigantic test-cheating industry, found mostly online, has given toxicologists like Dasgupta new problems to contend with. One popular formulation is called pyridinium chlorochromate (PCC). It destroys drug molecules in urine, potentially fooling drug tests.

But there’s a catch: the simple addition of some hydrogen peroxide will turn a PCC-containing urine sample dark brown.

Testing for Marijuana Use

“The bottom line is toxicologists are smarter than drug abusers,” Dasgupta told reporters at a meeting of the American Association for Clinical Chemistry in Washington. “If try to cheat on a drug test, we will catch you.”

That’s usually true. But even Dasgupta concedes there are some holes in his drug-testing net. He says parents should be on the lookout for over-the-counter eyedrops. A full vial of the easy-to-buy product can successfully mask THC — marijuana’s active ingredient — if it’s added to a urine sample.

This cheating method doesn’t work for heavy marijuana users. But for “borderline” tests, some eyedrops can envelop THC molecules, effectively hiding them from chemical detection, adds Dasgupta.

    Can’t you use salt water to throw off a home testing kit.

  • Confused👽 October 6, 2016, 9:04 am

    I’ve heard that salt water can cheat a home testing kit, is that true?

    I know for a fact that if you use very strong mouthwash like Dr.Tinchenors this mouthwash is extremely strong it’s the strongest mouthwash you can ever use usually you have to dilute it with water but I don’t and hydrogen peroxide if you put a little bit a small carry-on container that you can buy at Walmart one of those little bottles take it with you and use it in the bathroom with a small brush and use it right before if it’s a swab test with you’ll pass w/ flying colors and they sell this mouthwash usually at Walmart it’s not that easy to find and it’s extremely strong you have to at least try to leave it in your mouth for 10 seconds and it’s hard because it is strong and I’m not joking

    So I am pregnant but smoke marijuana like 3 times a day because I was getting sick and keep in mind I did not know I was pregnant at the time, I had to get an IV yesterday and that is when I found out I was pregnant. I have not smoked for about 5 days now but I have lost 5 pounds from throwing up constantly and now I am drinking lemon juice. I weigh about 112 lbs. I have a drug test today, do you think I will pass a urine test today?

    I noticed that just about everyone who has commented here is referring to smoking the night before and how to beat the tests.

    I’m interested in solutions for the the following scenario….
    Your at a friends house and you have had a few hydroponic (strong)bongs (maybe 10 or so) over the previous hour or two, how to you beat the test when driving home from your mates place?

    Ive heard about using strong mints and also gargling with white vinegar helps but I do not know for sure.

  • Nicole June 24, 2015, 1:48 pm

    Does it work on mouth swabs too? Cuz im searching for answers

    • mike November 2, 2015, 2:40 pm

      I’ve passed a cotten swab test by gargling a large amount of hydrogen peroxide multiple times right before you take the test. Allowing a small amount down your throat will also help ensure you 100% can pass. I’ve done it! Good luck

      Just Don’t Smoke Two Days Befor your drug test if it’s the swab and use mouth wash that morning Weed only last 12 hours in your saliva. I was a heavy smoker and had to take a mouth swab test for work just didn’t smoke for 2 days and was using Mouth wash like crazy those two days … Good Luck

    Does it truly work to use eye drops in your urine to pass a drug test for weed? I am 130 pounds 5″1 at height and I usually smoke like 2-4 times a day. I have a drug test tomorrow and I have been drinking a lot if water and I’m going to drink vinager tonight but I’m still worried.

    If you might have anything at all to do with cannabis seeds, you will know exactly how precious and how valuable certain strains are.
    Quitting her job at Digital Computer she agreed to my element working on Saturdays, a good time to meet potential franchisees.
    Some conspiracy theorists have claimed that pro-legalization groups are actually subversively planting the
    patches so that you can promote their agenda, but no proof exists thereby
    far no group has claimed responsibility.

    Dasgupta isn’t smart enough to recognize a non sequitur when one slaps that smug look off his face. The two problems aren’t even remotely equivalent. It’s an egg hunt where the testee must hide all the eggs where they can’t be found and can leave no trace of even being there. The tester gets to wade in with a bunch of “what’s supposed to be there” sieves and trash the place on a molecular level. At a certain point it will require magic.

    They can’t find a cure for alot of deadly diseases ( Aids ) or even ( cancer ) but they got time to catch people smoking bud.. Fucking scientists

    • Diane February 10, 2017, 2:43 pm

      Oh they found in the seventies, that marijuana wasn’t harmful and was actually helpful..president Nixon didn’t like that so much so we didn’t see anything about it..now cbd oil is a scheduled drug? Are ya fucking kidding me??? This could help millions of people but if the government and big Pharma aren’t making gazillions then it won’t be used to help ANYONE!!! Our whole system is fucked up!!!

    Wat if you do edibles will dat have a less chance

  • DLOCC March 27, 2011, 4:10 am

    DOSE THIZ REALLY WORK CUZ I REALLY WANT TO SMOKE WEED N MY FRIEND SAYS JUST DRINK VINEGAR. IM ON PROBATION N THIZ SEEMS LIKE I CAN DO IT?

    • GoodAdvice October 18, 2015, 1:07 am

      Do not consume any drugs on probation. Drinking vinegar isn’t a magic number for passing a UA. Partaking in the consumption of any drugs (even alcohol, although theres less of a chance) has like a 98% chance of getting you caught no matter what remedy you counter it with. Don’t test fate cause its a bitch.

  • Mr. 4000 November 14, 2010, 9:42 pm

    for the swab chew altoids.(chew. rinse.and repeat or eat) hard favors like mint..and 1 or 2.. 1 minute before test it stings but you will pass.good luck!!!!

  • Rob817 July 17, 2010, 1:30 pm

    Me too !! Preach

  • gregory burnett June 26, 2010, 1:08 pm

    I would like to no if peroxide,will work on drug test where they swab your mouth, and get your salava.and what would the results be.even if you are a heavy user, or a Holiday user.

    • random September 26, 2013, 1:11 am

      never heard of peroxide but know from experience simply brushing your teeth well and mouthwash for a good couple minutes is enough to pass the mouth swab. Not enough thc is in the saliva to fail a test unless you actually have resin in your mouth from the last time you had some.
