Those were a number of different statements. I agree with most of them.
I would say, though, that for some substances, the proper level of availability could be none. Carfentanil is 10,000 times more powerful than morphine. It has no use anywhere in any regulatory framework that I can foresee. Nitazenes and fentanyl are drugs that it would be very difficult to find a suitable availability for that is outside the medical system for the purposes of treatment, surgery, etc.
That's the only one of those statements that I would qualify in the sense that, for sure, we need to find a sweet spot of regulation, and, for some substances, that may be none.
