We all do things that can be considered sinful, harmful or potentially deadly. And we are free to criticize each other for these actions. We are free to attempt to persuade others to choose what we feel are acceptable choices. And we are free to accept the consequences of our actions.
Legalize the use of marijuana for adults. Tax it. Allow production for private use without tax, as we do for beer, wine, and tobacco. Regulate its use in public.
