Coolants in Puff electronic cigarettes present health hazard

Electronic cigarettes, or ECs, contain nicotine, solvents, and flavor chemicals, and are especially popular among young adults. In 2020, the Food and Drug Administration, or FDA, banned cartridge-based flavored EC pods, but this ban did not extend to "disposable" flavored EC products, such as Puff ECs. Unfortunately, the chemical composition and toxicity of the fluids in Puff ECs are largely unknown.
