According to a report by the Los Angeles Times New Service, a study of 161 prescription and over the counter medications showed that 65 of them produced false positive results surrounded by the most widely administered urine test. Ronald Siegel, a psychopharmacologist at UCLA said 'The rife testing and reliance on tell-tale traces of drugs contained by the urine is simply a panic aversion invoked because the normal technique for controlling drug use haven't worked very powerfully. The next epidemic will be trialling abuse."

Byrd Labs have in its possession an internal document from the Syva Company, maker of the widely used EMIT test. This document, leak by a disillusioned company employee, list more than 250 over-the-counter medications and prescription drugs that can end in false positives.

Among the items reported as causing false positive check results are:
Pain relievers such as Advil, Nuprin, Motrin and menstrual cramp medications approaching Midol and Trendar. All drugs containing the widely used pain reliever Ibuprofen are certain to cause positive sample for Marijuana. Non-steroidal anti inflammatories such as Naproxyn have cross react in blind test. These are often prescribed for runners, sports injuries to joint, and those suffering from arthritis.

Syva labs has just now reworked its Cannabinoid test and claims to enjoy eliminated this problem. But a Science magazine article (July 8, 1988) list Ibuprofen as cross reactive. Under the new administration guidelines THC testing level will be reduced to 50 nanograms. Many more THC false positives can be expected in 1994.

Dristan Nasal Spray, Neosynephren, Vicks Nasal Spray, Sudafed, etc. and others containing ephedrine or pnenypropanolamine. Over the counter appetite suppressants which contain propanolamine. Most adjectives nasal decongestants can cause a positive reading for Amphetamines. As the cross reactive register suggests at the back of this booklet, amphetamine false positives are the most adjectives.

Therefore, poppy seed represent a potentially serious source of falsely positive results surrounded by testing opiate maltreat." Clinical Chemistry goes on to verbs: Not only is it difficult to distinguish heroin or morphine name-calling from codeine, but dietary poppy seeds can impart a strong positive result for urinary opiate of several days duration that is confirmed by GC/MS analysis".

Nyquil Nighttime Cold Medicine will experiment positive for Methadone up to two days.

Black Skin. This is not a set-up! Those of African origin, sure Orientals, or pacific Islanders might test positive for marijuana.
