Opioids

Dipyanone

Street names: Dipyanon, DPP (diphenylpropylamine opioid)

⚡What it does

  • Synthetic opioid of the diphenylpropylamine family (methadone's chemical neighborhood) — full mu-agonist pain relief and sedation
  • Long-acting like methadone: effects stretch many hours and so does the overdose risk
  • Appeared in EU drug-checking and toxicology as nitazene supplies were scheduled and disrupted

⚠Key risks

  • Unknown-dose powder + long half-life = overdose that arrives slowly and won't let go
  • Same respiratory-depression kill mechanism as fentanyl; naloxone works but repeat dosing may be needed because dipyanone outlasts one spray
  • Withdrawal is long and grinding (methadone-like) — detox is harder than short opioids
  • Sold as everything from 'oxycodone powder' to 'legal heroin' — no label is trustworthy

✚Overdose signs

  • Slowed/stopped breathing, blue lips, pinpoint pupils, unrousable sleep
  • Naloxone NOW, call emergency services, repeat naloxone every 2–3 minutes until help arrives
