Sarah Silverman -- Yeah, I Got High ... AFTER The Emmys

Sarah Silverman brought weed with her to the Emmys, but that doesn't mean she was high during the show. Now LATER in the evening is a whole other story ...

On her way into the big event, Sarah showed off her pot vapor pen and when she won an award ... people thought her speech was a little all over the place.

But after the show, Sarah told our photog she didn't smoke before or during the show ... but planned on celebrating with it later on.

Cause that's what winners do.
