Or... how about we provide treatment for people who are abusing alcohol, drugs, etc? There are billions of people who can responsibly use alcohol. Banning it doesn't make any sense for those who aren't addicts.
What we need is to ban cooking at home. Government soup kitchens. All consumption needs to be documented and controlled.
This needs citation, seriously. Cooking at home, even cooking "insanely unhealthy" butter injected baked chicken at home, still seems to be a lot healthier for you than a hungry man dinner, so I think that the real issue is related to the preservatives and the salt & sugar required to mask those preservatives - that are used to unnaturally extend the self-life of pre-made and frozen food.
