The Room (2003)

[Drunk Monk]

Fair question.  A little of both.  Cheech & Chong were really only funny when stoned.  Harold & Kumar are funnier to stoners than sobers (I'm guessing) but aren't that much funnier when stoned vs. when sober.  Rogen, well, I'm guessing he's funny to people who don't really get stoned but like to say they are stoners because for some dumb reason, they think that's hip.  He is equally unfunny when stoned or sober.

People still say stoned, along with a lot of other slang, but stoned is still the standard.
