The students who go to school drunk or hungover only strengthen the offensive stereotypes that teenagers have to face. There is no argument that some teenagers abuse alcohol, but you have to look closer at those student specifically. Look at the lives they live outside of school; unemployed parents, domestic abuse, child abuse and neglect, divorce, poverty… All these things drive kids to look for another way out. You cannot simply say that the drinking age should be raised because of the kids who abuse alcohol with the current drinking age being 21. People tend to overlook the underlying and even common reasons that teenagers drink in the first place. Also, if you look at other countries who allow teenagers to drink, they have fairly LOW percentages of teenagers abusing alcohol, because drinking is a common, regular thing, that those teenagers are used to. It is a part of their culture. There parents teach them about the dangers of drinking too much, too often at early ages.
