A powerful opioid derived from Morphine, with 2-4x its potency. Infamous for a high addiction potential and fatal respiratory depression in overdose, C. R. Alder Wright first synthesised this compound in 1874 trying to find a less addictive alternative to Morphine. In recent years, it has often been sold cut with the extremely potent fentanyl, causing a spike in overdose deaths.
