Joe rogan is always high hahahaha.
To say joe rogan likes the weed, as a man who has appeared in god knows how many pro-pot documentaries, is a massive understatement.
He does stand up high, trains bjj high, des his podcast high. No doubt he does UFC commentary high too.
That said, it has zero effect on his ability to do his job.
He says he's never high when he does the broadcast. And being as he's a guy who makes such a big deal about being high, I see no reason he would lie.
