Drugs are rare, but do exist on campus. Campus Safety is very strict about enforcing the no-alcohol/no-drug rules, so searching drugs out would really be the only way to find them. Therefore, peer pressure to do drugs is quite uncommon at Samford. Knowing your friends is important because even riding with someone who has drugs in their car can get you into trouble, too.
Usually, the only public display of smoking consists of tobacco, which takes place at night or between classes. Even these cases are not very often, so either people are great at keeping their drug use a secret, or drugs are simply not a frequent practice among students.
