Puget Sound is a dry campus, which means that no open containers of alcohol are allowed, unless you are 21 and live still live in the dorms. At that point, you are allowed to drink in the privacy of your own room. There are also a few school-sponsored events that provide alcoholic beverages for special occasions, like senior gifts and such. The most prevalent drug at Puget Sound is alcohol, followed by marijuana, but this activity is done in the comfort of one's own room for obvious reasons. Some students may take harder drugs, but you don’t commonly see or hear about that. The frisky freshman may try to smoke in his or her room, and depending on the RA's ability to discern risky business, may or may not get caught. Often freshmen will "pre-game" in their rooms and then make the trek to the party, but you will often hear of an RA making a bust and writing them up.
The drinking scene changes as you move from freshman status to upperclassman. During the fall semester, a fortunate passerby may bear witness to the phenomenon of freshman clumping, where mass groups head to parties that they’ve heard of from upperclassmen or word of mouth. There may be a kegger or double kegger, but often it's BYOB, and if you're under 21 and are looking to partake in "illegal" activity, you will have to make friends with an upperclassman. For the most part, everyone stays close to campus to party together at a house party or frat dance party. You don't come to Puget Sound for the party scene, but this doesn't mean you won’t have the best of times!
