The long-standing addiction of sectors within the US population to opioid-based painkillers has become even more dangerous over the last few years. Fentanyl (CHEBI:119915), a synthetic opioid first synthesised by Paul Janssen (1926–2003) in 1959 is one of the most powerful painkillers on the market, being around 50–100 times more potent than morphine .
