TEST TYPES #
Methaqualone is a relatively rare substance of abuse in the United States since it was removed from the legal market in 1983. Though it is still on the list of substances tested for in some testing companies's extended drug tests, many companies have determined it to be not economically justified and no longer conduct this test.
CAUTION & DISCLAIMER #
Erowid's drug testing information is a summary of data gathered from site visitors, journal articles, websites, and other resources. Detection periods depend on amount and frequency of use, metabolic rate, body mass, age, overall health, drug tolerance, and urine pH of each individual. Many substances that are not tested for in basic or extended urinalysis tests CAN be tested for by a laboratory willing to go to the trouble, although that is uncommon.
