The U.S. Centers for Disease Control and Prevention said on the 8th that vitamin E acetate added to the smoke glass bong liquid of e-cigarettes may be the "culprit" leading to fatal lung diseases, but other factors cannot be ruled out yet.
U.S. CDC researchers detected vitamin E acetate in 29 patients' bronchoalveolar lavage fluid samples, which is an additive used in some glass bong king products. Researchers also detected tetrahydrocannabinol in 23 of the patient samples and nicotine in 16 of the patient samples.
Researchers said vitamin E acetate is also commonly used in health products and bath lotions, but inhalation of this substance has different effects compared with smearing on skin. U.S. CDC researcher James Pickel said vitamin E acetate will stick to the lungs.
U.S. CDC official Anne Saud said at a media conference call that this was a breakthrough in the agency's investigation into the cause of e-cigarettes. However, more tests are needed, and the existing evidence cannot rule out other factors leading to lung diseases.
Data released by the US CDC on November 7 showed that as of 5, 2051 confirmed and probable lung diseases related to the use of glass bong bowl had been reported in the US, with at least 39 deaths.
