MDMA was first synthesised in 1912, methcathinone in 1928, and mephedrone in 1929. For example, cathinone derivatives have been reported since the late 1920s. The terminology is confusing because although the description ‘designer drug’ seems to imply the creation of new drugs, many are not new. MDMA and fentanyl compounds were the most popular synthetic drugs initially. Fentanyl is an extremely potent analgesic, some 100 times more potent than morphine.

Because they vary in composition from batch to batch they are potentially dangerous for users. Based on chemical formulae for opioids, mescaline, and cannabis, they are created in laboratories under lax conditions for no defined medical purposes.
