It started with scattered reports of a mysterious lung illness and grew to become a national health scare. Now with the number of vaping-related deaths creeping up each week, California Governor Gavin Newsom is stepping in with an executive order to place stiffer restrictions on e-cigarette products. 

But even as Newsom and other government officials search for a way to respond, we’re still left with more questions than answers about the source of this disease, so at this point it’s still fair to ask: Do we even really understand the enemy we’re fighting yet? 

On this edition of KCBS In Depth we hear from a pair of Bay Area health experts to try to get a better handle on what threats vaping might pose and what could be done about it. 

Guests: 

• Dr. Sara Cody, the director of Santa Clara County’s Public Health Department and a county health officer
• Dr. Stanton Glantz, a professor of medicine and the Truth Initiative Distinguished Professor of Tobacco Control at University of California, San Francisco

Host: KCBS reporter Keith Menconi
