Thank you, Chair.
Dr. Ostiguy, you said—and I think everyone agrees—that vaping is safer than tobacco, that vaping is safer than cigarettes. That seems plausible to me. I can think of a number of reasons why that might be so.
I'm wondering about the body of research behind that. What do we have? Vaping has only been around, at least on the market, for about 10 years. Do we have really solid evidence that backs it up?
Dr. Ostiguy, we'll start with you.
