Pseudoephedrine being pulled from the shelves is one of the biggest crimes of our time.
Pseudoephedrine should be easy and plentiful to obtain. I don't care if people use it to make meth. What they do in their private time doesn't concern me. Not being able to get Sudafed when I'm sick kills me. It's not like those people won't be able to get meth some other way.
We let people buy cars and cause 43,000 automobile deaths a year. People should be able to live life without stuffy noses. Maybe license people to buy meds and take it away if they abuse it? That's better than the draconian system we have now.
And don't get me started on ADHD medication and their shortages.
Edit: and there are 178,000 alcohol related deaths per year in the US. If you're going to allow that without prohibition, then please let us unstuff our noses.
I'm tired of living in a nanny state when we let people buy and own guns and swords and flamethrowers. Simply hiking on a mountain can kill you. Must we install guardrails on all the high places?
It's not that bad of a negative externality. Honestly. Not relative to all the other ones we've deemed acceptable. This is weird picking and choosing that doesn't make sense.
