Something else to consider. For all intents and purposes, I don't think I've ever heard pharmaceutical companies or doctors ever posit the question of just what would happen if the production and manufacturing of these kinds of medications were to suddenly cease?

Maybe due to production costs, other economic/logistics problems, or even geopolitical issues. There has, to my knowledge, never been even a hint of a guarantee of any sort, to patients or the general public, that these drugs will always be available. That they have any intention to insure that they'll remain available. Let alone available with any kind of reliable quality assurance. That is a very dangerous and risky potentiality.
