The ONLY danger that has been identified is Myclobutanil

Why do you say that when the article you link to clearly also implicates Vitamin E acetate (a solvent), and doesn't even address the cause of the non-THC vaping cases. Do you think myclobutanil is responsible for the nicotine vape-related cases as well? If so, why?

NBC's vape cartridge testing is anecdotal, not scientific. They did not source cartridges that are directly associated with the cases the CDC is tracking. The sample size is also too small to make any definitive claims about anything. At best their tests suggest that black market vape cartridges can be dangerous, but because we do not know exactly how or where they sourced these cartridges even that is tenuous (they only tested 3 cartridges from legal dispensaries and who knows where they bought the illegal ones).

[....]it appears the public (and the media) have already forgotten that the mystery was solved!

It seems very far from solved.
