I hear you, invertedisdead. I guess IDK the ultimate solution towards safety, yet I think we need something that reinforces safety other than a reliance on the good intentions (or not) of the market makers.
Not "good intentions" but free market. The government can penalize makers of products if they don't disclose all the ingredients in that product. People can then choose how much safety they want to pay for. An immunocompromised person might pay extra for carts that have been handled under sterile conditions where I seek to avoid rat droppings in the oil. Brands can make whatever claim they think they want and there can be penalties if the claims are false--just like with other foods, drugs and cosmetics.
On another note and why I came, here's an update that lists some brands:

And, the most current CDC message:

Edit:
For those who don't want to read it all, one culprit is not things to thin the oil, but thicken it. (Because of our erroneous belief thick oil must be more pure.)
I wonder if this will filter back to True Terpenes putting mineral oil in their dilutant. They had a massive wholesale business. Who knows how many people were buying from them and, unknowingly, filling their carts with mineral oil.
The Leafly article linked mentioned True Terpenes. Apparently, the way everyone has been using it is wrong. At least, that's what the spokeshole says. (I'd like to see the marketing to know if such a defense would stand up.)
As health officials investigate the source of the lung injuries, another possibility includes legal substances used incorrectly. Think of an extreme version of off-label use, where a physician prescribes a legal medication for a condition beyond the drug’s intended use.
That can put the legal makers of these products in a bind. For example, consider the case of True Terpenes, a leading manufacturer of terpenes and diluents based in Portland, OR. Their products are meant for specific purposes. But they have no control over the uses to which their customers put the products once they’re shipped.
Ben Disinger, the company’s marketing manager, told Leafly their leading diluent brand, Viscosity, is “recommend for use in winterized extracts.” (Winterizing means removing the extract’s fats and waxes.)
Disinger said that one recommended use of Viscosity is for diluting THC oil in cannabis balms and lotions meant to rub on the skin, not for ingestion or inhaling. Using such a diluent in vape pens, he said, is not an approved use. Burning or inhaling Viscosity might or might not be harmful, he said, but the company has no data either way.
“Nothing is proven to be safe for vaping,” said True Terpenes Chief Science Officer David Heldreth. “We are aware that people are using it for that use. We don’t recommend or direct them to do that. We don’t inherently believe there will be a danger, but it’s not something we can speak directly to because no one can.”
