In addition to nicotine, some of the chemicals, like the carcinogen formaldehyde, are created when the nicotine-rich liquid in some vaping devices is heated to high temperatures. Concerns about vaping grew after a 2019 outbreak of severe lung injuries, which were subsequently linked to vitamin E acetate, an additive found in some vaping devices that deliver THC, the psychoactive ingredient in marijuana. Producers of Juul introduced changes that enhanced the palatability and safety of vaping, but at the same time “made it easier for kids to start using nicotine,” Dr. Wagener said. And Juul doesn’t require the high temperatures that produce toxic substances like formaldehyde. A single pod contains the nicotine equivalent of a pack of conventional cigarettes.
