Household & Commercial Masking Agents?
Both household and commercially available products can also be added to the urine sample with varying success. Some will defeat the on-site drug test while some will only defeat the laboratory test.
However, all these products will be detected using an on-site adulteration test carried out in conjunction with the on-site drug test.
There is currently no adulterant which can be added to urine which can guarantee success in defeating a drug test, provided an on-site adulteration test is carried out and the test is performed by properly qualified vigilant Collection staff. Some of the commercially available adulterants also contain chemicals which are acidic or poisonous in nature while others contain known carcinogens (chemicals that cause cancer) and hence care needs to be exercised by people who choose to use such products.
It should also be pointed out that drug testing policies generally treat proven adulteration with a greater penalty than a confirmed positive drug test, so any attempt to use a product of this type is likely to have drastic consequences for the individual if caught.
