You've probably seen those big, flavoured vape clouds rising from commuters at the bus stop and kids outside the mall. Cigarette smoking is down across the board, but more and more people are vaping. Critics say vapes are a gateway to addiction, while others point to their value as a smoking cessation tool. What does the evidence say? 

2:30 | Dr. Mark Tyndall, firner Director of the BC Centre for Disease Control and author of Vaping: Behind the Smoke and Fears explains how he became an "accidental advocate" for vaping. We cover nicotine vs. cannabis vapes, "popcorn lung," nicotine lip pouches, and more.
