In addition to the five drug groups found in the federally mandated tests, non-regulated drug testing can include the following:  Barbiturates, Benzodiazepines, Methadone, Methaqualone and Propoxyphene (Darvon).  Other drugs that are sometimes requested include meperidine (Demerol), cotinine (nicotine metabolite), LSD (lysergic acid dietylamide) and urine, blood and/or breath alcohol.

Others can include "X" (extascy) and "EVE" as well as BHB or other "date rape" drugs.

 We strongly suggest that methaqualone not be requested as a routine urine drug test because methaqualone has not been produced in the United States since the mid 1980's.  It  has been supplanted by many other drugs as one of choice.  Its use is extremely rare and is encountered so infrequently that its inclusion in a drug test is useless.  In scientific terms, testing for methaqualone has no predictive value.

Barbiturates is a class of drugs known as depressants and include at least eight separate compounds.  One Source Toxicology tests for five of the more common barbiturates:  amobarbital, secobarbital, pentobarbital, butalbital, and phenobarbital.

Benzodiazepines is a class of drugs known as anti-anxiety or hypnotics and include at least eight commonly prescribed medications.  The laboratory tests for the following benzodiazepines:  diazepam, oxazepam, lorazepam, temazepam and alprazolam. 

Opiates is a class of drugs known as narcotics or analgesics.  One Source Toxicology tests for four of the commonly prescribed opiates.  Codeine, Morphine, Hydrocodone and Hydromorphone.  Morphine is used as post-surgical pain killer but is also a metabolite of heroin.  The laboratory also tests for heroin by testing for 6-Acetyl morphine the intermediate metabolite of heroin when morphine is present at concentrations greater than 2000 ng/ml.
