In the 1960s, methaqualone - sold in the United States as the trademark Quaalude - was widely prescribed as a treatment for insomnia and anxiety. However, it soon became apparent that quaaludes were highly addictive and had a strong potential for recreational abuse. Throughout the 1960s and '70s, quaaludes were extremely popular due to their ability to produce a drunk-like state without a hangover. After years of scientific research revealed the harmful short- and long-term effects of using quaaludes, the drugs were made illegal and pulled from the market in most countries. However, quaaludes continue to be abused in many developing nations.
