By setting the same framework, the alcohol policies aims at promoting community, responsibility and respect.~The aim of the project is to evaluate the effects of the introduction of new mutual alcohol policies on students binge drinking.~The analysis is a natural experiment that compare binge drinking among students at schools after the introduction of the policy with binge drinking among students a schools that did not introduce the policy.
