April is "Alcohol Awareness Month." Today, to mark the occasion, students on more than 80 campuses in 34 states held rallies to promote what they say is a safer alternative to alcohol: marijuana.

Mason Tvert is the executive director of a pro-marijuana group called "SAFER" (Safer Alternative for Enjoyable Recreation), the group that organized today's rallies. In an interview, Tvert told the Chronicle for Higher Education he wanted students to think green next time they party: "It's not adding another vice. It's providing an alternative. A safer alternative. . . . Sobriety may be the safest alternative, but it's not a realistic alternative — at least for most students."
