About the drugs to be tested The eight drugs or drug classes to be tested are presented in the table below. THCA accumulates in the fat, and is released slowly into the blood, making its way to the urine. This is why the detection window is longer than for the other drugs. Cocaine use is determined by detection of benzoylecgonine, a metabolite of cocaine. Cocaine itself is metabolized too rapidly to be detected in the urine.
Opiates are a class of drugs including morphine, heroin and opium.
Some over the counter diet products and cold medications fall into this class, and will be detected. Methadone is a drug used in substance abuse treatment programs. It is a narcotic, like the opiates, and is sometimes sold by addicts undergoing treatment - therefore subject to abuse. Benzodiazepines are effective in treating anxiety and sleep disorders. Barbiturates are used as anticonvulsants and in management of migranes.
