Loyola University does not take drugs and alcohol lightly. If you are of age, then you are most certainly allowed to have alcohol in your dorm room. However, it must not be in sight of minors or in sight in any of the lobbies. If any student breaks these rules or is found with illegal drugs, they will be reported and will have to meet with the people at Student Conduct. Each case goes in a different direction as far as who overlooks it and what actions will be taken.
Drugs and alcohol are not a part of campus life. Students should not feel pressured to be engaged in anything. In fact, several organizations on campus host different events to help students not feel pressure to engage in drugs or alcohol.
