The couldn't we get this control done by the pharmacist then? It sounds like the issue is about controlling the distribution and educating people about usage. A pharmacist can do that. I can see that a doctor's medical advice would be necessary in the case where I don't know what my condition is and don't know how to treat it.

Not that I'm against this, not at all, but one could argue that having the antidote easily accessible would make some people take greater risks. Kindof like if there was a cure for hangover, alcohol abuse might rise.

Blue valve opens, gas gets injected, piston is pushed back up, gas compresses, spark, boom. Red valve opens and smoke exists. Note how the piston does 4 up/downs in a cycle. Only 1 of those steps is powered by gas dirextly. The 3 other steps are powered by the movement of another piston.
The real beauty in there is the cam shaft IMO. The green things moving the valve. They have to be perfectly configured andnthe gear ration needs to be precise otherwise the valve wouldn't open at the right time.
This is not my expertise though ... I could be wrong

I believe thisnis the best answer. Other answers only talk about preventing abuse, which is not really tied to the professional act of a doctor handing out the prescription. Understanding side effects is the true work of a doctor.
