Thank you, Mr. Chair.
I want to thank all of you witnesses for being here today, and unfortunately we don't have enough time to ask each one of you as many questions as we might have. I'm going to focus my questions on Mr. Cunningham.
Mr. Cunningham, I do appreciate your bringing some of these examples here. I have an email here from an emeritus professor of medicine at the University of British Columbia, at the Centre for Heart Lung Innovation. He has basically said that there is comparable risk for cancer and COPD—and COPD is chronic obstructive pulmonary disease—when you smoke a marijuana cigarette or a regular cigarette. Would you agree with that?
