This is the bias that people have against those who smoke marijuana. They usually immediately assume that they are lazy good for nothings, though this is typically untrue. Cannibias can also be reversed, meaning the bias stoners have for non smokers.
Dude that guy Dave is such a lazy piece of shit, all he does is smoke pot

He's working on his masters, runs marathons, and is working as an intern at a hospital, I think you're just Cannabiased
