DEA CODE 9822: Schedule 1 Narcotic

Synthetic Opioid

World Health Organization 2016:
  • Butyrfentanyl is a potent, short-acting mu opioid receptor agonist, and an analogue of fentanyl, differing by only one methyl group.
  • It has no approved medical indications, but is being used for recreational purposes, with cases of fatal overdoses reported in Europe and the United States. The actual extent of abuse and mortality associated with butyrfentanyl is not known because it is not tested for in routine toxicological analyses.
  • Typically used as a nasal spray, snorted as a white power, or injected intravenously, and doses range from 0.5 to 3 mg.
  • The effects appear to be similar to the effects of fentanyl, including euphoria, altered mood states, drowsiness, and respiratory depression.
  • Studies suggest that butyrfentanyl is about 30 times less potent than fentanyl
  • Butyrfentanyl is being abused for its opioid effects.
  • No accepted medical purpose has been identified.
