EA-3167
Developed as an incapacitating chemical weapon; a single dose of approximately 0.2-0.3 mg intramuscularly can incapacitate for up to 10 days. Physostigmine is the preferred medical countermeasure but requires repeated administration. Volunteer studies and civilian exposures reported lingering mood and cognitive disturbances for months. Recreational use is virtually non-existent due to extreme duration, severe delirium, and medical risk. Never weaponized or mass-produced.
