I don’t think that this happens because the kids involved want so badly to be a member of a group or organization. It happens because drug and alcohol culture is so deeply imbedded into colleges and universities that it becomes normalized. When you add in the huge amounts of money made by those who are involved in the trafficing of all these drugs (and who mostly get away with it), it’s not surprising that it’s rampant.
Let’s face it; it’s not just college administrators who turn a blind eye. Many, many parents tolerate their kids underage drinking and marijuana use in high school. They may say they don’t like it but they act like they are powerless to do anything about it and justify it by remembering their own youthful substance abuse. It’s not surprising that things escalate once these students arrive at universities.
