Summary
BZ is an extremely potent, long-lasting anticholinergic deliriant originally developed as a military incapacitating agent. Even sub-milligram doses produce profound delirium, confusion, vivid hallucinations, amnesia, and severe anticholinergic toxicity lasting days. Effects include dangerous hyperthermia, tachycardia, urinary retention, and complete loss of contact with reality. Medical intervention is often required. The unpredictable, intensely dysphoric nature and extreme danger make recreational use essentially non-existent.
