Our school's counseling center holds classes specifically for policy violations/discipline
ecision making class (making smart choices and how bad choices will get you in trouble) and Alcohol and Drug class (they talk about why it is bad and how it grows from alcohol to harder drugs), or just regular counseling sessions. Maybe approach the center about starting up 1 or 2 classes per semester.
I am working on a masters in counseling. For my alcohol/drug abuse class I went to AA meetings for an entire semester. I learned alot and they do not expect everyone there to participate. Many perticipants are not even sober while they are in the meeting. They have the chip that you can take to promise to stay sober for that day. At the AA office they have listings for open and closed meetings. Closed is meant for alcoholics but open is available for visitors. Also when a milestone is reached (1, 3, 5, 25 years...) many will bring guests to witness receiving that chip.
