As with most colleges, some students choose to partake in drugs. It is not a huge amount, and it is, of course, illegal. The most popular drugs around campus are alcohol and marijuana—though students have been in trouble for many others, including hallucinogens, pills, etc.
There is also a rave scene that has flooded Westminster's campus—not that all ravers do drugs. There are dubstep concerts and clubs in which drug use is more apparent. Whenever drugs or alcohol are found in underage students' rooms, these students are generally reprimanded, and in the case of drugs, kicked off campus.
