"The 21-year-old age limit does not prevent binge drinking. It happens at campuses all over the country, and I think if we were able to show responsible drinking and model responsible drinking and education for students, it would benefit everyone," said David Oxtoby, president of Pomona College.
The university presidents say their options for educating students about alcohol are currently limited because schools must tell them it's illegal to drink.
However, not all young people agree with the initiative.
"I think 18 is still too immature. Even 21 is still kind of pushing it," said Maricio Santos, a college student.
Mothers Against Drunk Driving is also critical of the proposal, fearing the initiative will lead to an increase in fatal car crashes.
