Recent research on the effects of alcohol policy changes.

As the agenda of alcohol problems prevention has broadened, new traditions of research have emerged: of experimental studies at the community or the societal level, of "natural experiment" studies of the effects of sudden changes such as strikes or new legislation, and of sophisticated time-series analyses of the effects of sudden and of long-term changes. While it has been shown that control measures can influence alcohol problems rates, substantial change seems to require changes in the political status quo, often also involving popular movements. Except for taxes, raising the drinking age and drinking-driving countermeasures, the political will to restrict availability has been lacking in market-oriented industrial societies in the modern era, so that the modern experience of the effects of other control measures is based on centrally-planned or non-industrial economies.
