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.
