Urine sample diluting This may be accomplished by either consuming a significant amount of water prior to the drug test or simply putting water in the urine sample. The evident drug levels would be reduced if the urine was diluted. As a result, the likelihood of a drug-negative outcome increases. Urine sample substituting It is also possible to substitute another person's urine for your own. For example, if you know that someone else has used drugs recently, you could have them submit a sample in lieu of you. Doing so would not violate any rules unless they told you they were going to fail the test. However, this could get tricky if you want to play games with their score.
Drugs can be divided into two groups depending on how they affect the body: depressants and stimulants. Depressants include alcohol, barbiturates, benzodiazepines, methadone, oxycodone, and propoxyphene. Stimulants include cocaine, ecstasy, methamphetamine, Ritalin, amphetamines, ephedra, and ginseng.
Stimulants increase blood pressure, heart rate, and respiration. This is why people who use them expect to pass their drug tests. But depressants are different. They slow down the central nervous system and the body's natural reactions to stress. Because of this, users of depressants can become sleepy, experience dizziness, lose consciousness, and even die from an overdose.
Common Methods of Avoiding a Positive Outcome If a tester drinks a considerable amount of water (at least one gallon) before a drug test, the urine gets diluted and drug metabolites may become undetected. As a result, the initial set of findings may be inconclusive. The person would not fail the test but would not show evidence of drug use either.
There are several methods used by people who intend to misuse drugs or abuse alcohol in an effort to avoid a positive drug test. Some common practices are described here. It is important to understand that unless you know what drugs are present in your body, it is impossible to say for sure whether they have anything to do with your negative result.
The first thing you should know about getting a negative drug test result is that there is no way to guarantee it. Even if you follow all the instructions properly, get a new sample taken at a different time, and so on, there is still a chance that the original test results will be positive.
It is best to assume that any drug found in your system has something to do with why you received a negative test result. This means that even if you think you did not actually use drugs, but someone else did and that person managed to fool the test, you would still need to be careful about what you do next time you take a drug-screening test.
Takeaway Diluted urine might make it harder to obtain reliable urine drug test results. However, this does not always imply that someone is attempting to "cheat" the exam. Some people may drink a lot of water in order to keep healthy or pass adequate pee. This is completely normal and has nothing to do with trying to cheat the drug test.
The truth is that whether you pass or fail your drug test depends on many factors, including the type of drug you took, how much you drank, how you stored your urine, etc. There are cases where individuals have passed their drug tests even after very recent use. However, these occurrences are rare. The only way to be sure what will happen with your test result is to take it first thing in the morning before any water drinking has taken place.
If your urine sample is clear down to zero minutes after sampling then there's a good chance it will show up negative on the drug screen. However, this doesn't mean you won't be tested again for prohibited substances later. It's possible that you might be asked to submit to a follow-up test several days or weeks after you were screened initially. If this happens then you'll need to be prepared to explain why you failed the first test or face being disqualified from job training or employment.
