ABSTRACT
Since ancient times, psychopharmacology has fueled armed conflicts and sustained fighting men. The presence of psychoactive substances in warfare has taken on two general forms: (1) combatants have consumed various intoxicants recreationally, and (2) drugs have been “prescribed” by military authorities as force multipliers for the improvement of combat performance. The chapter offers a general overview of these two modes of “war by intoxicants” yet with the main focus on the latter. It discusses the particular purposes of the military use of drugs, namely to inspire courage and provide relief from the stress of battle; overcome fatigue and enhance performance; lessen the effects of war on the psyche; maintain morale and cohesion; and kill the boredom and monotony of military life.
Aiming to draw a broader picture of battlefield drugs, it also explores another military role for them: as offensive psychochemical non-lethal weapons. Disorientation, indecisiveness, hallucinations, seizures, and other similar intoxication-induced effects offer potential military capacity. Thus, the efforts to weaponize toxic plants and psychoactive agents (such as atropine, opium, cannabis, or LSD) attempted to confuse, disrupt, or immobilize an enemy, or subvert and overpower their surrounding populations.
