What are Doping samples for a Drug Test?

1. "Doping" samples consists of spiking the sample with various chemicals.

2. Chemicals that defeat immunoglobulin/antigen binding will cause a false negative on the EMIT.

3. Most of these additives only work on the standard EMIT screening, if at all, but certainly not on RIA or GC/MS tests. In many cases, however, passing the EMIT is good enough, because they will never do a RIA or GC/MS confirmation on a negative sample.

Oberserved Drug Tests

You may be observed, so NeonJoint does not recommend this approach. Many of the following additives alter the urine's pH. Labs test the pH, nitrates, specific gravity and oxidants to see if the sample has been adulterated.

Household products and cleansers will be detected. Commercial additives, if they are not detected, probably will not work. This includes bleach, ammonia, Drano, hydrogen peroxide, soaps, etc. Again, commercial additives, detox products and synthetic urine are illegal in most states, and some commercial vendors will not ship their product to an address in those states.

If you are subject to random tests, you may want to consider keeping an immediate cleanser in your lunchbox or some other personal space where you could have access once notified of a  drug test.

Additives are illegal in several states, including Texas, and commercial vendors will not ship their product to Texas addresses.

List of Doping Samples for Passing a Drug Test:

8.1  Bleach

Chlorinated bleach could cause a negative result, and it's the most common household additive. In an emergency, Jeff Nightbyrd recommends adding unscented bleach crystals to a diluted sample. It's recommended to grind the powdered bleach to a finer grain. 1/4 teaspoon is recommended for a 60cc sample. For liquid bleach, add six to ten drops. Bleach will throw the pH outside the normal body range, so it may be readily apparent that the sample was tampered with. Some bleaches foam or leave residue, so experiment with different brands before selecting which to use if you are intent on using bleach.

Again, NeonJoint does not recommend using bleach to pass your drug test.

8.2 Klear©

Klear© is a powdered additive. Jeff Nightbyrd, Ann Waters Pearson and Party Hut Enterprises have at various points endorsed Klear. It was, until recently, the most advanced and least detectable doping solution. However, many labs can now detect Klear. Due to the popularity of Klear and a growing number of cases where people were caught using it, Jeff Nightbyrd now recommends reverting back to UrinAid. Klear can mask the THC metabolites, as well as nicotine byproducts on the EMIT. If methamphetamines are present, Klear certainly will not help. Klear is only designed to work on the EMIT. It will also work on the RIA when there is a good time span between the urine getting spiked and getting tested. If the RIA test is not performed onsite there is a good chance Klear will cause a false negative. Klear can be purchased from Martha Butterfield-Jay Foundation and Party Hut Enterprizes. You can also get Klear direct from their website.

8.3 Water

You can dilute your sample heavily with water. Do not confuse this with drinking water; you can also add water directly to the sample. Be sure to use hot water (between 91 and 97 degrees), as labs will take the temperature of the sample. You should note that this method is not dependable because – among other reasons – some facilities have the sink water shut off. If the administrator hears you turning the faucet on, it is very likely you will have to submit an additional sample.

8.4 Ammonia

While two ounces will render the sample negative, the pH is immediately altered and you will be given credit for a failure.

8.5 Blood

It's been said that a few drops of blood will fix your sample. Please know that this is a complete myth.

8.6 Drano

Drano will cause your test appear negative. However, Drano is strongly recommended against. Not only will it color your sample blue, but it will put the pH outside the normal body range. Drano foams and leaves metal specs that must be removed.

8.7 Goldenseal

Goldenseal placed directly in the sample does not alter test results. Do not dope your urine with Goldenseal. Goldenseal is more commonly used as a screen, to be consumed (Section 7.2).

8.8 Hydrogen Peroxide

Industrial-grade hydrogen peroxide will destroy roughly half of the THC metabolites in a sample. Household strength hydrogen peroxide does absolutely nothing. 30% H2O2 may "oxidize the THC metabolite into something that would not react in the screening test and would show up as something different by GC/MS."  

8.9 Lemon Juice

Lemon juice is a myth; it will not change the test results.

8.10 Liquid Soap

Soap will cause your specimen to test negative. However, it will also make your urine extremely cloudy and raise immediate suspicion.

8.11 Mary Jane's SuperClean 13©

This additive was effective for a very short period of time. SuperClean had to be strong enough to beat the tests, but weak enough to be undetectable. It failed to cause a false-negative in 3% of the tests. In fact, it also causes a false-positive on the EMIT for alcohol. Use at your own risk and discretion.

8.12 Purifyit©

Imported from Europe, Party Hut Enterprises sells Purifyit with a money-back guarantee. PHE claims there have been no returns. Oklahoma NORML refuses to endorse this product because it has flunked too many truck drivers.

8.13 Sodium Nitrate

This is slightly more effective than table salt, but dissolves very poorly.

8.14 Table Salt

Two tablespoons of salt will cause your urine to test negative, but puts the density entirely out of normal range. Residue can also be seen at the bottom of the cup.

8.15 UrinAid©

UrinAid©, produced by Byrd Labs, is very potent and works consistently for masking marijuana and nicotine, but not cocaine or heroin. Labs have recently developed a test solely to detect UrinAid. UrinAid is currently tested for in at least 15% of labs nationwide. Oklahoma NORML has stopped selling this product because it's "too detectable."

8.16 Vinegar

Adding vinegar to your sample will test negative, but also drops the pH. In fact, lowering the pH is what causes the sample to test negative. "If the urine is extremely acidic or alkaline the antigen-antibody reaction will proceed at a slower rate which could produce a false negative." This method is not recommended because even if you are lucky enough to lower the pH enough to produce a negative, nearly all labs test for pH.

8.17 Visine

Byrd Labs concluded that Visine does not work. Clinton said that the lab he worked in tested for Visine, and concluded that Visine works every time as a false negative for the EMIT. It can be easily detected due to the inability of the sample to foam.

8.18 WD40

WD40 can only hurt your chances of passing your drug test. Do not use it.

8.19 Papain

This is a papaya enzyme available over the counter. Currently, NeonJoint can neither endorese nor shoot down this method. Dr. Grow said that Papain is an antibody to THC, and in theory may destroy THC when added to the urine sample. However, positive urine doesn't actually contain THC; it contains THC byproducts. Papain has not been tested, and may or may not work. We will of course update this section when more definitive information is available.
