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
