When it is bad or fake medicine I would say!
Ah --- two different issues;
Issue one; if a particular treatment modality solves a patient’s problem, as long it’s his/her body, it's his/her choice.
It should be the individuals decision to part take or not.
Issue two; the person is being scammed, ie, sold a bill of goods that isn't as advertised. That’s a different deal.
Completely different situations.
I believe a person has sole jurisdiction over his or her body as long they aren't interfering with the same rights of others.
Shit if they want to do themselves in taking bad drugs, that’s their choice.
I will add, I don't like the gov., making decisions for me. I believe individuals have a personal responsibility for the decisions they make. Sometimes shit happens --- oh well.
Not sure where you're going with this --- but it's interesting.
