The title could be the entire article. Have you ever known a smart pot-head? Not coffee-shop ranting smart, but functionally smart.
I know a bunch of them. Lots.
They built and now maintain the internet. They likely built the building you're sitting in right now...to include electrical and plumbing.
They probably built the car you're gonna drive to Home Depot tomorrow.
Do you think Carl Sagan was stupid?
I’ve never met an admirable pothead. Okay there was this one guy and then he killed himself.
