A study by the Yale School of Medicine finds that banning smoking in bars affects drinking behavior, especially among smokers, men, and younger age groups. States with bans show higher reduction in alcohol use than those states without bans. Currently only 29 states have bans on smoking in bars. The results add to already established evidence of public health benefits of smoking bans, which have been shown to reduce tobacco-related illnesses. These findings call attention to an innovative legislative approach to decrease the morbidity and mortality associated with AUDs (Alcohol Use Disorder).
