Legalize it and tax it, fuck! how hard would that be you religious nut bags
You can't stop any of these, but you can punish those you dislikecwho violate your professed religion (that you violate on a daily basis) by making life more dangerous for them.
Bonus points: you get to make laws based on your fake religion, despite what the constitution says. I said fake, because the one your professed religion was named after would not recognize you as a disciple.
