The drug scene on Mount Union's campus is really only there if you're looking for it. Most students feel that less than half of their peers use drugs, and aside from a faint smell in the dorm hallway from time to time, it's really not that noticeable. The most popular drugs on campus are marijuana and prescriptions like Adderall and Vicodin; harder drugs like cocaine are much less prevalent, if used at all. The consequences for being caught with drugs or drug paraphernalia are severe, and may even result in expulsion from the University.
Alcohol, on the other hand, is a much different story. Social drinking is a popular pastime at Mount Union, and everyone knows it. There are strict rules in place regarding alcohol consumption on campus, but punishments tend to be mild, and there are still plenty of students (over 21 and otherwise) who drink. However, peer pressure is pretty minimal, and students say that no one will treat you differently for staying sober.
