You left out the trial lawyers...the real jack-booted thugs that strip billions from Health Care and Pharmaceutical every year either in settlements or outrageous insurance premiums resulting from excessive litigation.
Yes, that’s another irony:
Makers of purified pharmaceuticals are 100% liable for any failure to dream up the perfect scenario of possible misuse, and to make sure that under such misuse (and any accompanying overdosage), the drug remains perfectly safe, or else they get sued for billions.
However, if you never test your product’s safety at all, and you never purify it, it remains a “supplement” and you can make false claims about a deadly product and scarcely ever need to worry about lawsuits.
