Does he smoke pot in real life?

I could guess that he does or at least has in the past. Be just talks like a stoner.

I guess he does talk like a stoner, whatever that means, but he's way more productive and focused than most of the stoners I have known. There's nothing wrong with it whether he does or doesn't do it, but whatever he does in his life, it appears to be working because he's one of the most talented and hardworking talents in the business.

Lots of uses of the word "man", etc. It's a stereotype but it's often true.

That's for dang sure.

Hippies/Beatniks said "man" a lot. Born in LA 1949, probably had shitty mexican weed.
