Use of drugs in warfare

Use of mind-altering substances in warfare has included drugs used for both relaxation and stimulation. Historically, drug use was often sanctioned and encouraged by militaries through including alcohol and tobacco in troop rations. Stimulants like cocaine and amphetamines were widely used in both World Wars to increase alertness and suppress appetite. Drug use can negatively affect combat readiness and reduce the performance of troops. Drug use also poses additional expenses to the health care systems of militaries.
