Due to fear of losing a job, of being disqualified for employment, of losing privileges or freedoms, of losing child custody, or fear of other implication due to a positive drug test result, many people who use drugs find ways to "beat" the drug test system. This is especially advantageous to those who use/abuse drugs currently or regularly, who must test negative for drugs quickly. The following information explains how the drug test system can currently be defeated.

Physical Attributes of Urine

1. Color - yellow to yellow/tan

2. Odor - a distinct urine odor

3. Temperature - The human body's internal temperature is a constant 98.8 oF. When urine exits the body, it maintains a temperature of 96 oF (+/- 1 oF). Heat flows from hot to cold so when a hot object comes in contact with the cooler object, both objects will eventually reach equilibrium and their temperature will be equivalent to the surrounding environment.

In this case, when the urine enters the urine container the temperature of the urine is maintained at approximately 96 oF of (+/- 2 oF) for approximately 4 minutes. It is important to note the temperature within this time frame.

pH - Measures the acidity (sourness taste in limes, oranges, etc. and basicity (found in soaps, antacid medications).  Urine's pH should be between 5-6 (slightly acidic to neutral).

How it's done (How People Beat the Drug Test)

1. Adulterants

Taking an adulterant such as Zydot is one of the best way to test negative for drugs quickly. It is safe, natural, and can be purchased in most novelty shops, health, and nutrition stores. If done correctly, Zydot and similar adulterants have a > 95% efficacy. In most cases, a person using this type of adulterant produces a bright fluorescent yellow urine.


2. Submitting other person's urine

There are companies today that manufacture urine containing no drugs, that anyone can purchase. The Internet is a good source for locating companies that help beat the drug testing system.

3. Diluting with water or other substances

The addition of water or other liquid substance in urine to dilute the drugs can be successful if it passes the urine temperature test. Suggestively, turn off your bathroom sink water and add dyes in your toilet bowl.

4. Imitation Urine

In general, the physical appearance of urine should be yellow to yellow-tan in color. Unfortunately, there are liquid substances available such as apple juice, cranberry juice, etc., that have the same color as urine. Noting the temperature of the urine is important.

5. Length of time in the bathroom

The length of time that one spends in a bathroom could infer possible activity of altering the urine sample. You could confirm your suspicion to some degree by noting all-important criteria of temperature, color, and odor of urine. The temperature and odor of the urine can be confirmed at that point, because of the temperature indicator on the urine collection container, and obviously your smelling device, the nose. However, you are not required to smell the odor of the urine if you don't feel comfortable with this task. A specimen below 90 oF is enough to suspect an altered specimen. Please use your best judgment in any case. Some people may have difficulty in urinating, or generally prefer to take their time in the bathroom. Therefore, the temperature of the urine may not register to an acceptable temperature of 90 oF. The best solution is to have a patient resubmit a urine sample.

What to do with a suspicious sample

From time to time, you will encounter a urine sample that may not be acceptable because of appearance, temperature, color, etc. If it is strongly believed that the person is trying to beat the system, you could politely as them to submit another urine sample.

Conditions to recollect the sample

1. Temperature - If < 90 o F.

2. Color and odor

The color and odor of the urine may not always be a reliable indicator for possible alteration of urine. However, as long as the temperature of the urine is acceptable, we have a weapon called AlphaTox that overcomes all adulterants.

NOTE: : If recollecting the sample, try to do this within four hours to avoid further elimination of drugs from a drug users system.
