A saliva drug test is a potent tool that can help you discover whether someone is currently high on drugs, or if not currently high, whether they have used drugs quite recently.  In this way, you can think of it as a disposable breathalyzer for illegal drugs.  Amphetamines, methamphetamines, and cocaine all appear in your saliva 5-10 minutes after use, and it takes 72 hours, 72 hours, and 24 hours respectively for the drugs to disappear from your saliva.  A saliva drug test is the only home drug test that gives you the opportunity to tell whether someone is high.

Saliva drug testing works because there is a high correlation between the amount of a drug in your saliva and the amount of a drug in your blood.  Edward J. Cone, Ph.D., of the National Institute on Drug Abuse, has suggested that a saliva drug test could be useful for accident victims, automobile drivers, and those about to engage in risky, safety-sensitive work activities.

The features of a saliva drug test that are pointed out as “pros” by the Office of National Drug Policy in their brochure “What You Need to Know About Student Drug Testing” include:

• You can obtain the sample under direct observation – it is hard to tamper with it.
• A saliva drug test is non-invasive
• It reflects recent drug use

Another perk to mouth fluid testing is that it can measure even smaller amounts of a particular drug in the human body than a urine drug test can.  Whereas a urine test can measure 300 nanograms per mililiter of cocaine in the body, a saliva test can measure the presence of 20 nanograms per mililiter of cocaine in the body.

Home Health Testing’s saliva drug test can help you detect whether someone is currently high on one of 6 drugs:  marijuana, cocaine, opiates (which includes heroin, and morphine), amphetamines (which includes Dexedrine), methamphetamines, and phencyclidine (PCP).  If you want to know whether someone is or recently was under the influence of drugs, this is the test for you.
