This page contains basic information on the drugs our products can detect, and how long the drug residue remains in the body after use:

Amphetamines are central nervous system stimulants that produce alertness, wakefulness, increased energy, reduced hunger, and an overall feeling of well-being. Large doses and extended usage can result in higher tolerance levels and physiological dependency and may lead to substance abuse. The "D" and "L" forms of Amphetamine are considered controlled substances. DETECTION TIME: Amphetamines can usually be detected in urine for 1-2 days.

Barbiturates represent a class of commonly abused central nervous system depressants. They are usually taken by mouth but are sometimes injected into muscles or veins. Barbiturates range from short-acting (approximately 15 minutes, such as pentobarbital and secobarbital) to long-acting (24 hours or longer, such as phenobarbital). The SCREENERS® Barbiturate Test allows detection of both short-acting and long-acting barbiturates in human urine, with a high degree of specificity. The test is rapid, simple, and does not require special instrumentation. DETECTION TIME: Barbiturates can usually be detected in urine for up to 3 weeks depending on the type.

Benzodiazepines are a class of drugs that are often therapeutically used as anxiolytics, anticonvulsants, and sedative hypnotics. Being subject to abuse, tolerance, and dependence, these drugs are among the most frequently prescribed medications encountered in toxicological analysis. DETECTION TIME: Benzodiazepines are usually taken by mouth, and can be detected in urine for up to 6 weeks with chronic usage.

Cocaine is an alkaloid present in Coca leaves (Erythyroxine coca). Cocaine's properties, such as stimulating and euphoric effects, have been known for centuries. Cocaine has been used medicinally as a local anesthetic agent in the past, but its addictive properties have minimized its modern daily use. Cocaine is most often self-administered by IV injection, snorting, and smoking (by inhaling vapor given off when the free base is heated.) The availability of "crack" (a readily available street form of the free base) has increased the use by this latter route. DETECTION TIME: Cocaine can usually be detected in urine for up to 4 days.

Ecstasy or MDMA (Methylenedioxymethamphetamine) is a designer drug first synthesized in 1914 for the treatment of obesity, although today it is popular as a recreational or "club" drug. Effects include increased blood pressure and heart rate, perceptual changes, and a clenching of the jaws. DETECTION TIME: Ecstasy can usually be detected in utine for 3-5 days.

Marijuana is considered to be a major drug of abuse. The drug can be smoked or eaten, leading to psychoactive effects from the compound tetrahydrocannabinol (THC). Casual users of marijuana can test positive for the drug up to a few days after use, whereas chronic users can test positive for about a month. DETECTION TIME: Marijuana can be detected in urine for 2 days for a one-time user up to a month for a heavy frequent smoker.

Methamphetamines are central nervous system stimulants that produce alertness, wakefulness, increased energy, reduced hunger, and an overall feeling of well-being. Large doses and extended usage can result in higher tolerance levels and physiological dependency and may lead to substance abuse. D-methamphetamine is a controlled substance. DETECTION TIME: Methamphetamines can usually be detected in urine for 1-2 days.

Methadone is a commonly used substitute for heroin or other abused opiates in drug maintenance treatment clinics. It is administered by mouth or injected into the veins. DETECTION TIME: Methadone can usually be detected in urine for 3 days.

Opiates and their metabolites may be detected in urine as a result of heroin, morphine, codeine, or poppy seed intake. Morphine is a preferred drug in the management of pain in advanced cancer patients. Large doses of morphine can produce higher tolerance levels and physiological dependency in users, and may lead to substance abuse. DETECTION TIME: Opiates can usually be detected in urine for 2 days.

Phencyclidine hydrochloride, commonly known as PCP or "angel dust," is used primarily as a recreational drug for its hallucinogenic affects. It is generally self-administered by intravenous injection or by inhalation and concentrates fastest in fatty tissues and the brain. DETECTION TIME: PCP can usually be detected in urine for 14 days, up to a month for a heavy user.
