Mandrax
Methaqualone is a sedative-hypnotic drug that is similar in effect to barbiturates, a general CNS depressant. Its use peaked in the 1960s and 1970s as a hypnotic, for the treatment of insomnia, and as a sedative and muscle relaxant. It has also been used illegally as a recreational drug, commonly known as Quaaludes (pronounced /ˈkweɪluːdz/ KWAY-loodz) (particularly in the 1970s in North America) or as Mandrax (methaqualone 250 mg combined with diphenhydramine 5 mg). Since at least 2001, it has been widely used in South Africa, [1] where it is commonly referred to as “smarties”, or “geluk-tablette” (meaning happy tablets).
