I went through terminal cancer with both parents. It's infuriating that with that diagnosis the medical cabinet is open with respect to palliative care, in quantities that make an exit simple. But at the same time they feel the need to protect you from possible treatments. Potential accelerated death? Approved. Potential prolonged life? We'll need more evidence.
I think the Commerce Clause is a pretty sound basis for most FDA regulation.
It just gets weird with the overbroad supreme court decisions that are like: "well, stuff that only happens in a single state but that might be used for interstate commerce or somehow impact interstate commerce indirectly" is also covered. [1][2]
One can only get from regulating interstate commerce to telling a terminal patient what medicine he may consume by a tortured logical process driven by motivated reasoning.
