Same logic applies.
Well, not really, we have a constitutional right to bear arms, not a constitutional right to smoke shit. Still, it's not the act, it's the actor. Statistically speaking, how much damage does Salvia really cause? Pretty damn miniscule compared to alcohol even. It's not habit forming, despite what some people looking for attention say. There is no evidence that it causes any lasting effects. It is a shamanistic tool, can it be abused? sure... just like anything can be.
We can't foam-pad society, we shouldn't even try, if we continue in our efforts to eliminate the need to think and make decisions, people's skills at doing both will deteriorate, and you can't fix "stupid," which is the eventual outcome of that course of action.
