As an example, cigarette smokers as a group were horribly inconsiderate and often aggressively rude. They littered the ground and the air. The tar and the smell gets in your hair and clothes. They walked around burning people and things with their cigarettes. It was terrible. I don't miss it, even though I am sad that it took a broad law restraining everyone's behavior. That being said, even the possibility that pot smokers might become as obnoxious as tobacco smokers were before they were shunned en masse, it isn't a good argument against legalization.
