look up any word, like fleek:
 
1.
A pill/capsule that is a CNS Depressant (Central Nervous System) with similar properities to barbiturates, and similar addictive and withdrawal properities. It was quickly pulled from the markets in the USA as a result of wide-spread abuse, although it did enjoy a number of years as a near top-selling sedative/hypnotic before being made Schedule I and thus banned in the USA. Worldwide it is a Schedule II controlled substance under international law and thus available by prescription in most nations...

Quaalude is a brand-name for methaqualone (C16 H14 N2 O)... In other words, Methaqualone is a downer, a depressant, similar to barbiturates in most every way, although probably more addictive.

3.
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,"Lemmons", or "Lemmon 7s". They were not manufactured by the company that makes Maalox as some have indicated. 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.

6.
Slang for a type of methamphetamine called methaqualone. Functions as a sedative-hypnotic. Developed in the 60s by the same company that makes Maalox ( hence the double "a"s ).

Word History: Maalox got it's name for the "ma" in magnesium, the "al" in aluminum, and the "ox" from hydroxides. Quaalude borrowed the "aa" idea and the rest of the word perhaps derives from "quiet interlude" to describe the sedation effect.
