You may have noticed the large number of vaping stores that have popped up in the last several years around the Bay Area. It really seems like there’s one on every corner. Vaping nicotine–also known as e-cigarette use–has become a big business, particularly as the prevalence of smoking traditional cigarettes has waned in California and the United States overall. In this episode, we explore vaping. Just how bad for us is it? Is it a gateway to smoking traditional cigarettes? What are its consequences for our short- and long-term health? And, what exactly is a “vape?” Host David B. Feldman interviews Dr. Paul Brunetta, physician and co-author of the book, Learning to Quit: How to Stop Smoking and Live Free of Nicotine Addiction.
