Amphetamines describe the category, or drug class, that includes both amphetamine and methamphetamine. While the U.S. Department of Transportation (DOT) and Substance Abuse and Mental Health Services Administration (SAMHSA) requirements include MDMA under the group “amphetamines,” laboratory testing typically requires a separate, specific test.
Drug tests looking for cocaine and other drugs are routinely used by employers who hire workers in certain job categories. The test may be ordered once an offer of employment has been made and before the employee starts work.
Methadone is a synthetic opiate therefore is different from heroine, codeine, etc. In any drug test - be it an FBI type or the cheapest dipstick test sold at the local pharmacy - methadone is a separate category.
*The Methamphetamine urine drug test uses d-Methamphetamine as the calibrator for the stated 1,000 ng/mL testing level. The following table lists the concentrations of compounds (ng/mL) that are detected as positive in this urine drug test.
So sometimes oxycodone will show up on an opiates test, but not with the same accuracy as it shows up on an OxyContin / Vicodin test. The OxyContin / Vicodin test specifically tests for oxycodone in urine, so is much more reliable for that purpose than the opiates test, which detects morphine in urine.
Phencyclidine (PCP) was developed as an intravenous anesthetic but was discontinued in 1965 because of serious adverse effects on patients. As a Schedule I drug, PCP is a “dissociative drug” that can cause unpredictable behavior, increased pulse and heart rate, heightened blood pressure and temperature, possible mood and perception alteration, paranoia, panic, anxiety, nausea, tremors and suicidal urge.
Propoxyphene is in a group of drugs called narcotic pain relievers. Propoxyphene is used to relieve mild to moderate pain.
THC-COOH, though not psychoactive, is the primary marijuana metabolite screened for in workplace drug testing. While most drug metabolites are water-soluble and are excreted rapidly from the body, THC-COOH, is fat-soluble and thus exits the body slowly.
