Summary
Ethylbromazolam is structurally similar to bromazolam with an ethyl instead of methyl group on the triazole ring. User reports suggest approximately half the potency of bromazolam, with reportedly less sedation and amnesia than its parent compound. Estimated equivalence: 4 mg ethylbromazolam produces effects similar to 10 mg diazepam. Active at low milligram levels; volumetric dosing in ethanol or propylene glycol (1 mg/mL) strongly recommended. Drug-checking services in New Zealand, Australia, and the United Kingdom have detected ethylbromazolam in counterfeit Xanax bars and blue tablets since February 2025.
