The drug scene around City College is very low key. Drugs are definitely prohibited on campus, and most students wouldn't have a clue who to go to if they wanted to buy something. A majority of the students at City College are commuters and are only on campus for classes anyway, which helps keep illicit activites at bay. Students are pretty wise when it comes to doing drugs—education is priority—so why ruin your future by doing something illegal?
When it comes to legal things like smoking, though, it's different; there are tons of smokers around school. Certain areas on campus are usually filled with smokers, such as the entrances to the general buildings and outside the cafeteria. Don't worry about being pressured to join, though. It's rare for a student to pressure another to smoke, especially since cigarettes are crazy expensive in NYC so no one wants to share.
