Consumers must be informed when nicotine is present in vaping products and the addictiveness of nicotine. We support the prohibition on vaping products with nicotine concentrations of 66 mg/mL or more. Nicotine has not been shown to cause cancer in humans and has been safely used for decades in licensed nicotine replacement therapy products with few significant adverse effects-The International Agency for Research on Cancer does not list nicotine as a carcinogen.  Similarly, the US National Academy of Science, Engineering and Medicine (NASEM) in 2018 concluded that “there is no evidence to indicate that nicotine is a carcinogen” and that “there is likely no significant increase in risk of cancer from exposure to nicotine delivered by e-cigarettes.”
