Smoking in the United States military has been observed in previous wars, but smoking's close association with the United States military started in World War I when tobacco companies began to target military personnel through the distribution of cigarettes to servicemen and the eventual inclusion of cigarettes into rations. Although the military has attempted to implement tobacco control initiatives, the association between smoking and military personnel has persisted to the present day as smoking rates remain high, despite declines in civilian rates. Such high rates have led to questions about the effect of smoking from the apparent health risks to troop readiness and training costs. Smoking in the US military from 1917 to 1975 With the entrance of the United States into World War I in 1917, cigarette use increased dramatically among United States military personnel as they were targeted by tobacco companies which touted cigarettes as a way for soldiers to psychologically escape from their current circumstances, boosting overall troop morale. Tobacco was viewed as indispensable to the war effort; General Pershing said "You ask me what we need to win this war. I answer tobacco as much as bullets. Tobacco is as indispensable as the daily ration; we must have thousands of tons without delay." Cigarettes became so integrated into life on the battlefield that these symbols of pleasure and comfort were also used as a form of currency. Although cigarettes had been regarded as a physical and moral hazard by early anti-tobacco movements around this time, by 1918, previously anti-cigarette organizations and the military began supporting efforts to distribute cigarettes to troops. The New York Times garnered support for these efforts by stating that cigarettes "lighten[ed] the inevitable hardships of war", and another popular periodical described cigarettes as the "last and only solace of the wounded." With the rise of World War II, tobacco companies continued to foster this culture of wartime smoking by sending free cigarettes to troops and supporting the inclusion of cigarettes into the soldiers' rations. Advertisements also encouraged citizens back home to support the troops by sending cigarettes. In 1965, first during the U.S. Army's Basic Training Course and later in Pre-Airborne Infantry Training, while being allowed a break from P.T., or during a long march, it was commonplace for a drill sergeant to say "smoke 'em if you got 'em, do pushups if you don't." Non-smoking soldiers would quickly "bum" a cigarette
