EA-3167 is a potent incapacitating agent and long lasting anticholinergic deliriant drug, related to the chemical warfare agent 3-Quinuclidinyl benzilate (QNB). It was developed under contract to Edgewood Arsenal during the 1960s as part of the US military chemical weapons program, in an attempt to develop non-lethal incapacitating agents.

EA-3167 has identical effects to QNB, but is even more potent and longer lasting, with an effective dose when administered by injection of as little as 2.5μg/kg (i.e. 0.2 milligrams for an 80kg person), and a duration of 120-240 hours (5-10 days).[1][2] However unlike QNB, EA-3167 was never weaponized or manufactured in bulk.
