How to Pass a Drug Test with Hand Sanitizer in 2024

Recently, hand sanitizer has been creating quite a buzz, and everyone wants to know how to pass a drug test with hand sanitizer.

In this article, we’ll get to the bottom of the claims and find out if a bottle of cheap hand sanitizer can beat a urine drug test.

People try all kinds of cheating methods when they face taking a drug test.

You’ve probably heard about using mouthwash and chewing gum to beat a saliva test.

And of course, there are urine substitutes and specialty adulterants you could use for a urine test. But those are expensive and there’s no guarantee they work.

How To Pass A Drug Test With Hand Sanitizer 2024: What’s The Process?

How To Pass A Drug Test With Hand Sanitizer

The hand sanitizer method for adulterating urine before a drug test is actually very simple.

Fans of this method report that you need to get a small bottle of hand sanitizer; one that’s small enough to hide inside your underwear.

When it’s time to give your sample, you go into the bathroom, add enough hand sanitizer to the collection cup to cover the bottom, then pee into the cup.

Adding hand sanitizer to a urine sample will only be possible if your collection is unobserved. If your sample collection is supervised (someone watches you pee) you won’t have a chance to adulterate your sample.

What Kind Of Hand Sanitizer Are People Using?

There’s no particular brand that people favor for this method.

It would, however, make sense to use a brand that doesn’t have any added color or fragrance which would raise an obvious red flag the moment you handed your sample over.

Another type you should probably avoid is those foaming hand sanitizers because a cup full of bubbly pee would reveal your adulteration attempt.

Does Hand Sanitizer Produce A Negative Result On A Urine Test?

Alright, so we know that hand sanitizer is one substance used to cheat a urine drug screen, but does it work?

It’s no good relying on internet hocus pocus to try to pass a drug test when your job, professional license, child custody, freedom from returning to jail, or some other hugely important part of your life depends on the result.

We dug around to see if we could find a research study to back up these claims about passing a drug test with hand sanitizer.

Here’s what we found.

Study name: Effect Of Urine Adulterants On Commercial Drug Abuse Screening Test Strip Results.

Study URL –

In a study looking into urine adulterants, researchers added common substances to urine samples known to contain the following drugs.

  • Opiates
  • Cannabis
  • Amphetamines
  • MDMA (ecstasy)
  • Cocaine
  • Benzodiazepines

They tested various household cleaners, a hand sanitizer, vinegar, lemon juice, citric acid, and eye drops.

In their tests, the researchers took a urine sample, which was positive for one drug, and added the adulterants.

Then they performed a drug test on the adulterated sample using urine testing strips purchased from a company that supplies labs and pharmacies.

The Hand Sanitizer

One substance they used as an adulterant was a product called Asepsol.

This is an alcohol-free hand sanitizer available in Serbia, which is where the study was carried out.

We checked out the active ingredient in that product and found that it is 5% benzalkonium chloride.

This ingredient is widely used in alcohol-free hand sanitizers available in the United States.

However, the concentration of benzalkonium chloride in the alcohol-free hand sanitizers we looked at was much lower than 5%.

These hand sanitizers contain between 0.11% and 0.13% benzalkonium chloride.

Does Hand Sanitizer Work On A Drug Test: What did the Study Show?

On urine samples adulterated with benzalkonium chloride hand sanitizer, these were the results.

Upon testing for opiates, the urine samples tested positive.

Upon testing for cannabinoids, the urine samples tested negative.

The level of THC in the urine sample before adulteration was 112.2 ng/L. The cut-off level for cannabis in a drug test is 50 ng/L or below. So the hand sanitizer produced a result below 50 ng/L.

For the other substances tested, amphetamine, MDMA, Cocaine, and benzodiazepines Alprazolam, and Diazepam, the test became invalid with the urine sample triggering the mechanism used to detect sample adulteration or malfunctioning test strips.

What Can We Learn From Those Results?

What Can We Learn From Those Results?

This study demonstrated that a urine sample adulterated with a hand sanitizer whose active ingredient is 5% benzalkonium chloride, produced a negative result when tested for cannabis with commercially available urine drug testing strips.

This study doesn’t tell us anything about alcohol-based hand sanitizers, or even if the same urine sample would pass or fail a more rigorous laboratory gas chromatography/mass spectrometry analysis.

It doesn’t prove or disprove general internet claims about passing a urine test with hand sanitizer.

Even though the hand sanitizer produced a negative result for cannabis, the concentration of the active ingredient in the test product was much higher than the amounts present in the hand sanitizers we looked at.

Could you rely on the results of this study to try to pass a drug test with hand sanitizer? It wouldn’t be wise.

Test Yourself Before Your Real Test

To know if this method will work for you, you’re going to have to test it for yourself. It’s time for a home science experiment.

Supplies You Will Need

  • Alcohol-based hand sanitizer
  • Alcohol-free hand sanitizer
  • Clean sample cup
  • ML measuring cup and 1ml syringe
  • Urine testing strips
  • Your drug positive urine sample

Why test both kinds of hand sanitizer?

Since you’re doing an experiment, you may as well test both kinds and see which type gives the best result.

Using the alcohol-free hand sanitizer makes the most sense because it’s the type used in the study, but as we already mentioned, the concentration of the active ingredient in available hand sanitizers is much lower.

Testing the alcohol-based hand sanitizer is a good idea because this is the type most people are probably using when they report passing a drug test.

How Much Hand Sanitizer To Use

In the study, the researchers added adulterants to 1 ml urine samples. For the alcohol-free hand sanitizer, they added 0.2 ml. This is 20% adulteration.

Why did they use this urine to hand sanitizer ratio?

The researchers used the amount that gave a negative test result without changing the appearance or odor of the urine sample.

To be clear, you’re only using these tiny amounts while you experiment. Once you know what ratio works, you can scale it up for a full-size sample.

The best way to measure these small amounts is with a 1ml syringe.

You can easily buy these over the counter at pharmacies. A 1ml syringe has 0.1ml increments marked on the side.

Squeeze out a small amount of hand sanitizer into a container, then use the syringe to draw up 0.2 ml.

Squirt that out into a separate container.

Now draw up 1ml of urine and add that to the 0.2ml of hand sanitizer.

Draw the mixture back into the syringe, then saturate the test strip with your adulterated urine, following the instructions that come with your test strips.

Wait for a few minutes, then read your result.

If your result was negative, you can scale the amount you need to use. If it was positive, then the sanitizer isn’t going to work.

Testing A larger Sample

When you go in for a urine drug test, you’re usually asked to provide a urine sample that’s at least 60ml.

So, working with that number, measure 60ml of your urine with the measuring cup and add 12ml (20% of 60ml) of hand sanitizer.

Look at the sample and make sure the color hasn’t changed. Smell the sample and make sure it doesn’t smell of hand sanitizer.

Now perform a new drug test and see if you get the same negative result.

If your test went well, take an empty plastic bottle that’s small enough to hide in your underwear and add 12 ml of hand sanitizer to the bottle. Mark the outside of the bottle with a line, then add another 12ml and mark that level.

Now you have enough hand sanitizer to adulterate two urine samples in case there’s a problem with the first one.

Test the alcohol-based hand sanitizer in the same way, but you could start with a lower 10% concentration to see if that works.

Other Ways People Try To Adulterate Urine

People have tried pretty much every substance you can think of to adulterate urine when they need to take a drug test.

The researchers in the study tested some of the more common ones.

  • Vinegar
  • Lemon juice
  • Citric acid
  • Toilet cleaner
  • Bleach
  • Eye drops
  • Liquid soap
  • Household cleaners
  • Nitrates
  • Primosept antibacterial tablets
  • Zinc salts

Of these, only vinegar and lemon juice produced negative results without invalidating the test.

Vinegar with an acetic acid level of 9% produced a negative result on all urine samples, except the sample positive for cocaine. The concentration used was 20% –  0.2ml per 1ml urine.

Lemon juice produced negative results for cannabis, MDMA, and benzodiazepines. The concentration used was 40% –  0.4ml per 1ml urine.

There is one important point that you need to be aware of though.

The researchers also tested the adulterated samples with reagent strips and pH strips. Testing a urine sample with these strips can reveal adulteration and these tests are done when samples are sent to a lab for analysis.

When the urine sample adulterated with hand sanitizer was tested with a reagent strip, the result showed an invalid level for protein values.

Vinegar and lemon juice both altered the levels on the reagent test, but not enough to prove tampering. The pH test revealed tampering with the urine sample adulterated with lemon juice

The researchers concluded that the hand sanitizer and the vinegar both produced negative results for some substances, and these adulterants were largely undetectable upon further investigation.
