COMBAT EXPOSURE, CIGARETTE CONSUMPTION, AND SUBSTANCE USE
研究美国现役军人中战斗暴露与吸烟、酗酒、吸毒等危险健康行为的关系，发现经历交火的军人更可能从事这些行为，且心理健康效应可解释约三分之二的关联。
This study estimates the relationship between combat exposure and several risky health behaviors: cigarette consumption, binge drinking, and drug use. We find that the U.S. active duty military personnel deployed to combat zones with enemy firefight are more likely to subsequently smoke cigarettes, consume alcohol, and use illicit drugs than their counterparts deployed to noncombat operations. Our results suggest that the mental health effects of combat can explain up to two‐thirds of the estimated association between combat exposure and risky health behaviors.
