Use
Methaqualone, a quinazolone derivative, was introduced in 1965 for use as a sedative-hypnotic drug. It is widely abused and is associated with severe withdrawal symptoms. Methaqualone is controlled under Schedule IV of the 1971 Convention of Psychotropic Substances. (Reference: (UNCPS4) United Nations Convention on Psychotropic Substances (IV),1971)
