What will visine do to a drug test

Even the basic EMIT tests will detect the slightest variations in the temperature range of the urine in the laboratory. Other than dilution, Visine and other eye drop brands hide the drug metabolites in urine, thereby making them less available for detection in tests. It is said that Benzalkonium chloride, the main active ingredient in Visine, together with the aqueous solution of the eye drop, creates hydrophobic and hydrophilic layers where they trap the drug metabolites.

A lot of studies have been carried out to prove that Visine does help create a false negative during urine drug tests. One of the most commonly referred works of literature is Dr. This guide lists Visine as the only over-the-counter drug that can be successfully used to invalidate immunoassays when testing for drugs such as marijuana, cocaine, and opiates, among other drugs.

Referring to a previous study that had been carried out to analyze the effects of Visine eye drop on drug screening and how mechanism involved, Dr. Amitava notes that in low concentrations, Visine causes a false-negative because of its key active ingredient: benzalkonium chloride.

This study suggests that when several drops of Visine are added into a urine sample, a portion of the marijuana metabolites THC-COOH is hidden in the eye drop's aqueous solvent component. Fortunately, most labs rely on EMIT test credit for its simplicity regarding the equipment needed. These findings are confirmed by yet another research experiment whose findings were published on the National Institutes of Health.

This study aimed to analyze how Visine eye drops lead to a false-negative in urine cannabinoid immunoassay screens. Ask U. Educational text answers on HealthTap are not intended for individual diagnosis, treatment or prescription.

Can you use visine to pass drug test if so how much? Ed Friedlander answered. Forget it: The lab will probably report that you adulterated the specimen, and it doesn't work. What are the causes of a high ph in the urine on a random drug test? Robert Marvit answered. Alkaline: Anything that turns uirne alkaline so it would be oral ingestion of a variety of substances.

Neal Kraus answered. It may be used for:. Sports organizations. Professional and collegiate athletes usually need to take a test for performance-enhancing drugs or other substances. Legal or forensic purposes. Testing may be part of a criminal or motor vehicle accident investigation. Drug screening may also be ordered as part of a court case.

Monitoring opioid use. You may have to take a drug test as a condition of your employment, in order to participate in organized sports, or as part of a police investigation or court case. Your health care provider may order drug screening if you have symptoms of drug abuse. These symptoms include:. For a blood test for drugs, you will go to a lab to provide your sample. One of the most common ways of trying to pass a drug test is by using household products such as eye drops to alter the test results to create a false negative.

Visine is an easy choice, especially for those who smoke marijuana because they most likely already own some of the over the counter eye drops to mask the redness that smoking marijuana causes in their eyes. Visine contains two chemicals that have been said to create false negatives for THC in urine samples. Benzalkonium chloride, which is a preservative, and borate. The benzalkonium, in laboratory testing, was shown to reduce the amount of 9-carboxy-THC in urine sample by two thirds by, basically, absorbing the THC molecules into the benzalkonium cells.

The test concluded that milliliters of Visine per one liter of urine would be the exact amount needed to create a false negative result in a drug screen. The typical acceptable urine sample is somewhere around 60 mL so in order to cheat the drug test, you would need to add in exactly 6 mL of Visine. The laboratory testing of adulterating a drug test using Visine also concluded that any more or less of the Visine outside of the 6mL would be ineffective. The acceptable amount of THC in urine to pass a drug test is 50 ug per liter.

There are several different types of drug testing that can be performed by the testing facility and, more than likely, you will not know which test the laboratory will be using. Because of the different types of testing that are available today, eye drops has been proven to be ineffective for passing a drug test in a variety of different methods. Visine will also not be helpful in trying to mask drugs such as cocaine, heroin, methamphetamines, prescription drugs, barbiturates or anything other than THC.
