By the ninth grade, Phillip Fuhrman was already addicted to Juul, as were many of his friends. Some of them had reservations about using the e-cigarettes. Nicotine is bad for you, right? But their concerns about vaping were quickly explained away by a speaker who visited their school in April 2018 to give a presentation about mental health and addiction. Fuhrman testified to Congress in July that the speaker said he was connected to Juul, and told the kids that e-cigarettes were “totally safe” and that the US Food and Drug Administration (FDA) would soon announce that Juul products were 99 percent safer than regular cigarettes.

On Monday, the FDA chastised Juul for these and other scientifically unsubstantiated claims that advertise e-cigarettes as “modified risk tobacco products,” suggesting they are safe, relatively risk-free ways to quit smoking. Marketers can’t make those claims unless the FDA has reviewed the products and agrees that the company has rigorous scientific data to back them up. In a separate letter, the FDA requested Juul turn over information about its youth marketing strategies and Juul’s use of nicotine salts.
