To me it immediately connotes a recreational use, which is a useful distinction from purely medical (or pseudo-medical) applications.

So the word seems appropriate even if part of the familiar venacular.

that makes sense. What is pseudo-medical? Drugs to alter mood can be prescribed, but if they aren't is it recreational or self medication? If boredom is causing distress, could the drugs taken to ease it be considered medical? That may be a really bad idea for robust mental health, but sadly that is sometimes true for the prescribed drugs as well.
