Why are people who smoke Marijuana treated so strictly by society in some States....

...(Please read)? I'v noticed that the in some U.S. States, people who smoke marijuana are treated like they are a junkie or a bad guy, they are kind of looked down upon and some will say "you need to go to rehab, you have a drug problem" when they get caught smoking a single joint. I'm from Canada, and here Marijuana is very contraversional but even those who are highly against it, don't look down upon the poeple who smoke it like they are a junkie. My dad was a cop and he was againts marijuana use, he thought marijuana use was wrong BUT he would never look down at someone like they were a junkie if they smoked pot. I mean, it's not like crack-cocaine or heroin. People who use those drugs are junkies but not pot users. In some States, if you smoke pot in high school, you could be in a lot of trouble and they will guilt you so much you would think pot is the Devil's drug, but here in Canada, if you smoke pot at school, they would send you home at worst. It's frowned upon, but the teaches don;t think you have a drug problem if your caught with a joint, maybe if you were caught with a gram of cocaine they would think you have a drug problem, but not over pot.

I just want to know why???
