U.S. Surgeon General Vivek Murthy has released a new report calling e-cigarettes “a major public health concern.” “E-Cigarette Use Among Youth and Young Adults: A Report of the Surgeon General,” the first comprehensive review on this public health challenge from the nation’s highest public health authority, features input from Keck School faculty. The report offers insights into youth e-cigarette use, which has more than tripled since 2011, and outlines dangers to which young people are uniquely vulnerable. Jonathan Samet, MD, MS, Distinguished Professor and holder of the Flora L. Thornton Chair in the Department of Preventive Medicine at the Keck School, contributed to the development of the chapter on e-cigarette policy. Samet, who is also director of the USC Institute for Global Health, is an expert in tobacco and public health.
