Which raises the question, what what the real goal in preventing people from buying functional medicines?
Frankly I think the specific intent was exactly this. The main effect was to cause human suffering and Occams razor tells me the main effect was probably the intended effect.
I think Hanlon's razor is more appropriate.
Somewhere there was a team of people in the government who worked untold hours studying this, proposing solutions and ultimately having change enacted. This would have been good for career progression for all involved, not because it was actually good, but simply because they did something. And therein lies government.
In the DEAs case it was literally confirmed to be operating on malice since at least the Nixon and Reagan years, when it was deliberately wielded as a weapon to disrupt hippies and black communities, specifically.
Because it ruins people's lives, that's why.
I'm all for medicine that helps people and amphetamines absolutely can, but methamphetamine doesn't help people. It enslaves them.
That is with out getting into the debate on if it is even ethical for a government to regulation what a person consumes, even if you believe it is the current method of criminalization and prohibition is not effective in the stated goal of reducing drug use/abuse, a lesson we should have learned as a society with the passage of the 18th amendment and its repeal the 21st amendment
Of course that is not the real goal but .....
I don't know how it compares to organzied production, but people certainly do cook meth from retail pseudoephedrine. In my neck of woods, it's a fairly popular pasttime, since all ingredients can be purchased in a single trip to a shopping mall.
Thanks DEA, you used to just be able to get that in Nyquil and all the others, but the DEA in their moronic idea that drug dealers are going and buying precursors from the local CVS (not stealing them in bulk) has to abuse millions of law abiding sick people forcing them to sign the "papers please" log book treating them like criminals for wanting to feel better.
