so, if you're going to tell me you should have the right to smoke in your own home, i'm going to tell you i don't believe in property rights and point to public health measures as the more pressing concern.
you don't have free reign to burn paint in your backyard, and you shouldn't have free reign to smoke drugs in it, either. there has to be some stricter health regulations in place.
but, don't put them in jail - just write them tickets.
