Flunitrazolam
Street names: FNTZ, Flunitraz, Designer triazolo benzo
⚡What it does
- Ultra-potent triazolobenzodiazepine — hypnotic, heavy amnesia; active at sub-milligram doses
- Stronger per milligram than flubromazolam; more sedative-hypnotic than anxiolytic
- Cheap and easy to synthesize, so it keeps reappearing in pressed pills after each ban
⚠Key risks
- Multi-day blackouts and compulsive redosing — the amnesia hides how much you took
- Potency cliff: powder doses are measured in tens of micrograms; a scale error is an overdose
- Withdrawal is seizure-and-psychosis territory; dependence forms within weeks of daily use
- Fake-pill market: buyers think they are getting Xanax and get a much longer, stronger benzo
✚Overdose signs
- Unrousable sleep, vomiting while unconscious, breathing slowed (far worse with opioids or alcohol)
- Cannot be woken — call emergency services; place on side (recovery position)
