Thankfully, Biola is a school where students aren't peer-pressured into drugs or alcohol. Rather, the students on campus would try to convince their friends not to abuse such substances. Biola students are "on contract," which means that they can't have drugs or drink on campus in the first place, so students aren't even allowed to. Breaking the contract results in expulsion, so most students take this topic very seriously and steer clear of the mere temptation.
Campus Safety is very clear with students, and also keeps them up-to-date on those rare cases where events do occur, but Biola's campus is virtually void of any and all drugs, and has a very good reputation regarding the topic.
