Samples of lung fluid from patients with the mysterious illness led to a breakthrough in finding a possible cause. More than 2,000 people have been sickened, many from illicit marijuana-based products.
A form of vitamin E has been identified as a “very strong culprit” in lung injuries related to vaping THC, health officials reported on Friday, a major advance in a frightening outbreak that has killed 40 people and sickened 2,051.
Many patients with the mysterious illness have wound up hospitalized in intensive care units, needing ventilators or even more desperate measures to help them breathe. Most are young, male adults or even teenagers.
