Alcohol and drug abuse is both a consequence and a cause of violence.
Today have the courage to intervene in a caring way. Through your honest and straightforward communication, encourage yourself and others to get educated, get help, and get sober and free from drugs.
"[So what would Buddha do if a friend is abusing drugs?] When someone goes wrong, it is right for his real friends to move him, even by force, to do the right thing. ... Do not examine the limitations of others. Examine how you can change your own." -- Buddha
