Your argument has been that you do care what plants I eat by virtue of your defense of our corporate prescription system, whose purpose is to put people who eat plants without permission in prison. Remember?
I am in favor of some things being available by prescription and some things being available over-the-counter, just as they are now. However, I would not have the same things be both.
Also, I'm not sure what plants are available by prescription. The only plants I can think of that people take recreationally that are federally scheduled are cannabis and psilocybin and they are not available by prescription, nor do I think they should be. I think they should be legal.
On the other hand, I would put cigarettes behind a prescription wall.
