The state can enact reasonable regulations, but in this case I say they ought not require the provision of harmful and lethal drugs. This is not a matter of individual whimsy. It has been an explicit part of medical ethics for 2500 years.
So far as I know, states have plenary authority to regulate economic activity except where it would contravene some specific prohibition. Can you point to even a single example of the Court rejecting a state regulation based on the 9th or 10th Amendment?
