This article describes a CDC report on just 29 of the more than 2000 vaping-related illness cases. Those of us who read scientific studies will see all the facts that ARE here, as hanging together — 100% of those studied had the additive at infection sites; “stickiness” that could interfere with good lung function — and also note that 29 is a rather small number and the fact that the CDC hasn't found the precise manner in which this chemical works. For a lay person's story {Yahoo!), this seems a very well-written distillation of the medical research, including both the successes & challenges of public health.

A "breakthrough" feels like a bit of an overstatement. They just found something that is present in all the lungs of 29 tested patients. It may very well be present in the lungs of all the people who vape, and therefor not the sole causative agent. The majority of the article reflects the caution of the CDC to describe this as the causative agent better.

This was a very well-sourced and balanced article on a topic that has been sensationalized a lot lately. The article provides lots of context, facts, figures, quotes, and evidence that help paint an accurate picture of the current health crisis. This is the best article I've read so far on the topic.
