Editing Designer drug (section)

====1920s–1930s====
Following the passage of the second [[International Opium Convention]] in 1925, which specifically banned [[morphine]] and the [[acetyl|diacetyl]] [[ester]] of morphine, [[heroin]], a number of alternative esters of morphine quickly started to be manufactured and sold. The most notable of these were [[dibenzoylmorphine]] and [[acetylpropionylmorphine]], which have virtually identical effects to heroin but were not covered by the Opium Convention. This then led the Health Committee of the [[League of Nations]] to pass several resolutions attempting to bring these new drugs under control, ultimately leading in 1930 to the first broad analogues provisions extending legal control to all esters of morphine, oxycodone and hydromorphone.<ref>{{cite journal|url= http://www.unodc.org/unodc/en/data-and-analysis/bulletin/bulletin_1953-01-01_2_page009.html |title=Esters of Morphine |journal=UNODC Bulletin on Narcotics |year=1953 |issue=2 |pages=36–38}}</ref> Another early example of what could loosely be termed designer drug use, was during the [[Prohibition era]] in the 1930s, when [[diethyl ether]] was sold and used as an alternative to illegal [[alcoholic beverage]]s in a number of countries.<ref>{{cite book | vauthors = Brecher EM |title=The Consumers Union Report on Licit and Illicit Drugs |publisher=Consumer Reports Magazine. |year=1972 }}</ref>
