Dr. Ware, I have a question for you. I'm going to challenge one of your comments in saying that it lacks high-quality research. I can see that in some ways, but we've been getting briefs from the Canadian Medical Association, for example, saying the research is very clear. For people under the age of 25, there are clear associations with psychological problems and damage due to cannabis use. The Canadian Paediatric Society also says the association is very clear.
Could you clarify what you mean by a lack of “high-quality research”? I know the science isn't there for a lot of this, but as far as damage, would you agree that for people under the age of 25, there is clear evidence that it can cause psychological problems and sometimes permanent impairment?
