Myths on Passing a Drug Test


These two words strike fear in the hearts of many employees …even if they haven’t done anything. Drug testing isn’t meant to be used as a fear tactic. It is meant to be a  method to ensure that companies maintain a safe and productive workplace. Nonetheless, casual and chronic drug users go to great lengths to make sure they pass their drug test. There are many myths on how to pass a drug test.

 Drug testing isn’t meant to be used as a fear tactic.


This is also known as dilution. Many think that drinking extra water weeks or even days before the test will flush their system of THC, which is found in marijuana, or other test positive triggers. The trouble with this is that it can dilute your urine below test positive levels, and now most tests also track levels of creatinine. Creatinine isthe byproduct that is produced when food is turned into energy. It travels through the blood and is removed by the kidneys and passed out of the body through urine. If the creatinine level in your urine is found below normal, you may be suspected of tampering with your sample and be called in for a more extensive test.


Adulterants are any foreign substance added the urine sample. Common substances used include bleach, Visine, ammonia, and vinegar. The idea of adding the products to urine came from the idea of trying to or hide drug toxins. All of the substances with the exception of vinegar are added directly to the urine sample. Today’s drugs tests can detect these adulterants. Some think drinking vinegar a few days before a test can flush their system as well. It only lowers the pH level in the urine, not the metabolites which are used to test for drug use. Drinking too much vinegar can cause violent diarrhea.


THC, the chemical found in marijuana, metabolizes and stores itself in your body’s fat cells. So if you get rid of the fat, you get rid of the tell-tale THC right? Wrong. Unless you know your drug test is two months away, it’s not a plausible method to clean your system. It can take a long time to lose the amount of weight needed to test negative on a drug test.


Diuretics are liquids like coffee, tea, and cranberry juice that cause you to urinate more often. You’d have to drink a lot of these liquids and urinate often to even come close to completely flushing your system. Diuretics also eliminate key natural ingredients from your system that would be present in your urine sample. Drug tests detect this kind of tampering and could cause you to fail your test.


The majority of detoxification products cause you to urinate more, having the same effect as drinking plenty of water. As stated above, this can lower your creatinine levels which can be a trigger for a positive test. Some detox methods include high fiber intake which causes more bowel movements. Fiber blocks fat storage in the body. Since THC stores itself in fat cells and fiber blocks fat, many try to start high fiber diets before a drug test.
