Actually it is just the opposite, in the libertarian world the market to develop fantastical new drugs and combinations of drugs for getting high would be unlimited and all the giant pharmaceutical companies and new drug companies and basement drug companies and drug cartels, would be entering the market, and they wouldn't have to worry about safety concerns or side effects or fatalities, since they would all fit the libertarian area of recreational drugs.

As the text you omitted (underlined) from your "reply" shows, you're flat wrong - people who want to get high but not get arrested have an incentive under drug criminalization to use new poorly-understood drugs that they would not have under drug legalization. There would probably still be a small number of nuts with no sense of self-preservation - but drug criminalization can't stop them today because it's not possible to write a law against drugs that don't yet exist.

You're hallucinating - libertarians believe the law has a proper role in punishing actual direct harms such as you describe.
