There isn’t a lot of drug activity happening at Mudd, aside from some pot smoking. Those who want to try drugs can find them pretty easily, but there is no pressure at all to use drugs, even if you hang out with people who do use them. Linde and West, and sometimes North Hall, are the most prevalent drug scenes, with people occasionally smoking from a bong outside on the Linde couches. South Hall is completely substance free, and East, Case, and Atwood Halls are not known for much drug activity at all.
As is the case for most of Mudd, the prevailing rule here is “be safe.” People who do use drugs do them in the company of friends, so that there’s less chance of getting hurt or doing something stupid. There isn’t a lot of drug usage at Mudd, although some students take caffeine or Adderall to help them study. If you go looking for drugs, they’re easy to find, but you can go through Mudd without even noticing them if that’s what you want. When doing drugs, the Honor Code still applies to all students. Students are expected to file a self-report if they do anything stupid. Campus Security will, for the most part, leave students alone, unless they get too rowdy or cause trouble.
