A Crisis: Electronic , Vape, and Susan C. Walley, MD, CTTS,a Karen M. Wilson, MD, MPH,b Jonathan P. Winickoff, MD, MPH,c Judith Groner, MDd

Electronic cigarettes (e-cigarettes) and vape devices have rapidly become the abstract most common products used by youth, driven in large part by marketing and by e- companies. There is substantial evidence that adolescent e-cigarette use leads to use of combustible tobacco products. E-cigarette companies commonly advertise that e-cigarettes contain , flavoring chemicals, and ( and/or vegetable glycerin), but , ultrafine particles, and have also been found in e-cigarette solutions and emissions, many of which are known to cause adverse health effects.

In the scientific literature, e-cigarettes are commonly referred to as electronic nicotine delivery systems. Because they commonly contain nicotine, which is derived from the tobacco plant, e-cigarettes are tobacco products.1

Among younger age groups in the NHIS, adults aged 18 to 24 years had the highest rates of e-cigarette use, with 5.2% reporting “every day” or “some days” use.38 The MTF survey in 2017 revealed higher rates of current e-cigarette use at 11.3% among younger adults (ages 19–30 years), FIGURE 4 with use among 19- to 20-year-olds Percentage of middle and high school students who currently use e-cigarettes and any tobacco- at 13%.33 However, the highest rates, – products based on NYTS 2011 2018.
