"Doping" samples consists of spiking the sample with different chemicals. Chemicals that defeat immunoglobulin/antigen binding will cause a false negative on the EMIT. Most of these additives only work on the standard EMIT screening, not on RIA or GC/MS tests. In many cases, passing the EMIT is good enough, because they will never do a RIA or GC/MS confirmation on a sample that showed negative. I should also add that you may be watched, so don't rely on this method. You should be able to find out ahead of time if you will be supervised. Some of the following additives alter the urine's pH, and most labs now test the pH to see if the sample has been adulterated. If you are subject to random tests, you may want to carry an additive in your wallet. Additives are illegal in the state of Texas, and commercial vendors will not ship their product to Texas addresses.
Effective additives: These additives are recommended.
Bleach (powdered): Chlorinated bleach will test negative, and it's the best 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 apparent that the sample was tampered with. Some bleaches foam or leave residue, so experiment with different brands before selecting which to use.
Water: You can dilute your sample heavily with water. Don't 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), they will likely take the temperature of the sample. This method isn't dependable because some facilities have the sink water shut off so people can't do this. If there is running water, they may listen to you. If you turn on the water, make it sound like you're washing your hands or something.
Ineffective additives: These additives are not recommended. Many of these may give negative test results, but are not recommended for other reasons.
Ammonia: 2 ounces will render the sample negative. The pH is altered, and the ammonia odor is strong enough to be recognized.
Blood: It's been said that a few drops of blood will fix your sample; it doesn't.
Draino: Draino will test negative. However, Draino is NOT recommended because it doesn't work well even when half a teaspoon is added. It colors the sample blue, and will put the pH outside the normal body range. Draino foams, and leaves metal specs that must be removed.
Hydrogen peroxide: Industrial grade will destroy half the THC metabolites. Household strength hydrogen peroxide does 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"
Lemon juice: Lemon juice is a myth; it will not change the test results.
Liquid soap: Will test negative, but makes the specimen cloudy, which certainly draws suspicion.
Mary Jane's SuperClean 13 (c): This additive was effective for a very short period. 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! Don't use it.
Purifyit (c): 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.
Sodium nitrate: This is more effective than table salt (below), but dissolves poorly.
Table salt: Two tablespoons of salt will test negative, but puts the density out of normal range. Residue can also be seen at the bottom of the cup.
UrinAid (c): UrinAid, produced by Byrd Labs, is very potent and works every time for masking pot and nicotine, but not cocaine or heroin. They have recently developed a test solely to detect UrinAid. UrinAid is tested for in 5% of the labs. Oklahoma NORML has stopped selling this product because it's "too detectable."
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" (anon1). This method is not recommended because if you are lucky and lower the pH enough to produce a negative, there's a chance that the pH itself will also be tested.
Visine: This is debatable. Byrd Labs concluded that Visine does not work. Clinton said that the lab he worked in tested Visine, and concluded that Visine works every time as a false negative for the EMIT. It can be detected due to inability of the sample to foam.
WD40: Another myth. WD40 can only do harm.
Untested additives
Papain: This is a papaya enzyme available over the counter. It isn't known whether this does anything. 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.
If you fail the test, raise hell. Failing the drug test has been known to make a quiet person go ballistic. You will be interviewed by a medical review official (MRO), who would try to find out why you tested positive. MRO's are NOT impartial. An MRO is an employee of the lab, and is there for quality control. They are also there to protect the lab by coercing the court into thinking that the person who failed is a drug abuser. "Anything you say to an MRO can and will be used against you" (RDW). If you fight it, your lawyer "can subpoena the proficiency testing records of the laboratory for review" (anon1). These questions should be asked about the lab you are challenging:
How does the lab handle samples?
Are they NIDA/CAP certified?
Do they participate in appropriate proficiency testing?
Whay is their track records in the proficiency testing program?
Have they ever failed a proficiency test?
What are the qualifications of the technical staff performing the test?
What technologies do they use to screen and confirm?
