Alcohol policy conventionally has been established at the national or regional, state and provincial levels. Alcohol policy at any level is not actually limited to the regulation and control of alcohol production, wholesale distribution, and retail sales. There are a number of alternatives for setting alcohol policies within a local community. Building upon existing national and state/provincial laws, policy makers at the community level can set priorities for allocating resources and enforcing laws related to drinking and driving, underage alcohol sales, alcohol serving practices of bars and restaurants and geographical density of alcohol outlets in the community. This paper concludes from the Community Trials Project that policies established at the local level can reduce alcohol problems.
