CNN) -- A lot of college students feel pressured to binge drink, says University of California, Berkeley, student Joseph Bui.
Roz DeKett let her 18-year-old daughter, seen here on the left holding a glass, drink wine when they traveled to Italy.
The 20-year-old says he is bombarded by images of college students partying with kegs and cases of beer.
That's why he supports the drinking age limit of 21.
Bui thinks students would simply start binge drinking at 18 if the age were lowered -- and the problem would be exponentially greater because peer pressure in high school is even stronger than in college.
The debate over the legal drinking age usually comes down to this: If you're old enough to serve on a jury, die for your country and decide who should be president, are you old enough to drink?
