CHICAGO: Tests of lung samples taken from 29 patients with vaping-related lung injuries suggest all contained Vitamin E acetate, a discovery U.S. officials described as a"breakthrough" in the investigation of the nationwide outbreak that topped 2,000 cases this week.
She cautioned that more work is needed to definitively declare it a cause, and said studies may identify other potential causes of the injuries as well. Although the substance was detected in all 29 of the lung samples, which came from patients in several different states, more testing is needed to establish a causal link between exposure and injury, Schuchet said, adding that"many substances are still under investigation."On Thursday, the CDC reported there have been 2,051 confirmed and probable U.S. lung injury cases associated with use of e-cigarette, or vaping, products in 49 states, the District of Columbia and the U.S.
In the CDC analysis, THC was detected in 23 of 28 patient samples of lung cells, including from three patients who said they did not use THC products. Nicotine was detected in 16 of 26 patient samples.
