Drinking age of 21 saves lives
The national policy that set a minimum legal drinking age of 21 is being questioned by a group of 135 college and university presidents through an effort called the Amethyst Initiative.
But history and a comprehensive review of the research tell a much different story. The evidence is clear, consistent and compelling: A drinking age of 21 has led to less drinking, fewer injuries and fewer deaths.
That's according to the University of Minnesota's Toben Nelson (pictured), Traci Toomey, and John Finnegan, Jr. The three authored a commentary that appears on the CNN.com website.
They say:
"Lowering the drinking age will not save lives or make our campuses and communities better places to live. It will increase heavy drinking and the problems that accompany it in college communities and push the problem back into high schools. Real prevention requires constant vigilance, dedication and the courage to implement difficult solutions."
