So the fact that weed is illegal means there could be an anti-smoker bias? One based purely on the law and not any other reason? Probably. I still say legalizing pot smokers should be the next civil right.
Certainly, it would remove a lot of the stigma of pot as contraband and pot smokers as criminals. Fine, upstanding citizens don't want to be associated with criminals, right?
One based purely on the law and not any other reason?
I don't think so. People already have a bias against tobacco smokers and that doesn't have any criminal law component. Habitually smoking (or vaping) any substance is viewed as a vice and a moral shortcoming. It also tends to make a person smell bad and people naturally feel a bias against bad smells.
The fact that smokers are accustomed to the smell and don't notice it is also frustrating. It's an externality.
