The Challenge Almost 3,000 cases of vaping-related lung illness have been reported in the US, with 68 confirmed deaths in 29 states. The US Centers for Disease Control and Prevention have found the vitamin E acetate was strongly linked to the outbreak. However, some patient lung biopsies showed signs of chemical burns that vitamin E acetate alone would not be expected to cause. In August 2019, the US Centers for Disease Control and Prevention reported an increasing number of lung injuries following the use of some vaping products, and vitamin E acetate was identified as one possible cause. Though some patient lung biopsies showed signs of chemical burns that vitamin E acetate alone would not be expected to cause. Vitamin E acetate, primarily found in illegally made THC-based vape liquids, is considered non-toxic in vitamin supplements and skin creams. This research from Royal College of Surgeons Ireland (RCSI) has now shown that heating up vitamin E acetate through vaping can produce ketene, a highly toxic gas. Ketene is a colourless gas with a penetrating odour. When inhaled, it can cause serious damage to the lungs up to 24 hours after exposure. It is lethal at high concentrations, and at lower … Continue reading Confirming chemical in some vaping devices generates toxic gas
