Smoking is allowed for adults (Komoe and Aiho smoke at one point). Drinking is probably allowed as well, but I can't think of any examples right now.

These activities are probably forbidden for the students, but the rules don't seem to be well-enforced: in NT2, Shiage suggests that Touma drink to raise his spirits, and the latter does.
