A systematic review analyzed 50 studies on increasing the tax or price of alcoholic beverages, of which 31 analyzed outcomes relate to alcohol consumption and the reduction of violence and crimes associated with alcohol consumption (including drunk driving), as well as other outcomes, such as injuries and deaths from traffic accidents.
A doubling of the alcohol tax was estimated to reduce traffic deaths by 11%. Significant decreases were found in alcohol-related morbidity and mortality, and in the prevalence of risky behaviors, including drug use. The effects in terms of reducing crime and violence were statistically significant, although the magnitude of the effects found was comparatively smaller in these cases [1].
