Stoned on mj such that the smile you smiled when you smoked up is still there plastered all over your face an hour later because you neglected to unsmile or were too lazy, once the smile was there, to remove it. Comes from smoking good shit, or really bad shit -- depending on your definition: ergo "shitfaced". From this perspective (regional usage, perhaps) it has nothing to do with alcohol. (i.e. No shit, Sherlock.)
"Wipe that silly grin off thy face, thou shitfaced bastard... dost thou want thy boss to know thou art stoned?"
"Man, you are shitfaced... from ear to ear."
"Hey you shit-faced ex-pot-virgin, welcome to the smile high club!"
"Man, you are shitfaced... from ear to ear."

when you get so f*cked up that you shit on the ground and pass out in it, then you wake up and its on your face.

Shitfacing yourself consists of smoking marijuana and getting really drunk at the same time, simply because you are screwing your system up really badly with two substances that are harmful in their own ways.
