Methaqualone is a sedative-hypnotic drug that is similar in effect to barbiturates, a general central nervous system 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 (Template:Pron-en KWAY-loodz) or Sopors (particularly in the 1970s in North America) depending on the manufacturer. 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). Clandestinely produced methaqualone is still seized by government agencies and police forces around the world.

Methaqualone was first synthesized in India in 1951 by Indra Kishore Kacker and Syed Hussain Zaheer,[2][3] and was soon introduced to Japanese and European consumers as a safe barbiturate substitute.[citation needed] By 1965, it was the most commonly prescribed sedative in Britain, where it has been sold legally under the names Malsed, Malsedin, and Renoval. In 1965, a Methaqualone/antihistamine combination was sold as the sedative drug Mandrax, by Roussel Laboratories (now part of Sanofi-Aventis). At about the same time, it was becoming a popular recreational drug (called "mandies" or "mandrake" or "mandrix"). In 1972, it was the sixth-bestselling sedative in the USA,[4] where it was legal under the brand name Quaalude; at that time "luding out" was a popular college pastime.[5]

Effects

Effects can include euphoria, drowsiness, reduced heart rate, reduced respiration, increased sexual arousal (aphrodisia), and paresthesias (numbness of the fingers and toes). Bigger doses can bring about respiratory depression, slurred speech, headache, and photophobia (pain in the eyes when exposed to light).

An overdose can cause delirium, convulsions, hypertonia, hyperreflexia, vomiting, renal insufficiency, coma, and death through cardiac or respiratory arrest. It resembles barbiturate poisoning, but with increased motor difficulties and a lower incidence of cardiac or respiratory depression. Toxicity is treated with diazepam and sometimes other anticonvulsants.

Recreational use

Quaaludes became increasingly popular as a recreational drug in the late 1960s and early 1970s. The drug was used during sexual activity because of heightened sensitivity and lowered inhibition coupled with relaxation and euphoria.[citation needed]

The drug was often used by people who went dancing at glam rock clubs in the early 1970s and at discos in the late 1970s. One slang term for Quaaludes was disco biscuits. In the mid 1970s, there were special bars in Manhattan called juice bars that only served non-alcoholic drinks that catered to people who liked to dance on methaqualone.[6]

The drug was more tightly regulated in Britain under the Misuse of Drugs Act 1971 and in the U.S. from 1973. It was withdrawn from many developed markets in the early 1980s (in 1982 in the United States), being made a Schedule I drug in the U.S. in 1984.

Smoking methaqualone, either by itself or as an adulterant added to various legal and illegal smoking mixtures, gained popularity in the U.S. among a few during the mid-1970s. Because the various binders and inert ingredients that were contained in the pill form were toxic when smoked, this practice was roundly decried by the medical community as a serious health risk. Smoking methaqualone pills can lead to emphysema and other chronic lung disorders, most notably talcosis.

South Africa

Commonly known as Mandrax, M-pills buttons, or smarties, it is not taken orally but is crushed and mixed in a pipe with marijuana. Methaqualone is one of the most commonly used hard drugs in South Africa.[1][7] The low price (South African Rand 30 R average, which is about $4 of methaqualone) together with the ready availability of cheap, low-grade marijuana make it (in addition to methamphetamine and temazepam) the preferred hard drug of the low-income section of South African society.[1]

Slang terms

Methaqualone was manufactured in the United States under the name Quaalude by the pharmaceutical giants "Rorer" and "Lemmon" with the numbers 714 stamped on the tablet, so people often referred to Quaaludes as 714's, and also as "Lemmons." After the legal manufacture of the drug ended in the United States in 1982, underground laboratories in Mexico continued illegal manufacture of methaqualone all through the 1980s, continuing the use of the "714" stamp, until their popularity waned in the early 1990s.

Other widely used slang terms (given here in the plural) used for the drug methaqualone included: Disco Biscuits, Gorilla Biscuits, Down And Dirtys, Joe Fridays, Leg Spreaders, Lemmons, Lovers, 'Ludes, Mandies, Mandrakes, Q's, quas, quaas, quacks, quakers, Quads, Soapers, Suppers, Vitamin Q, The Love Drug, and Wallbangers.[6]
