Well, there are many anti-smoking (cigarette) laws in the US that are just what you're asking for for pot. In a lot of places, you can't smoke in public places, and somewhere they recently added a law that you can't smoke outside your apartment.

And there are lots of ways to consume marijuana that don't produce smoke or a smell.

So there you go. Now quit saying it shouldn't be legalized for your stupid selfish reasons.

And don't eat chicken if you don't like the smell that chicken production makes.
