I go back to what I said earlier that, in general—and in general is very important—cannabis is rarely harmful, but there are some specific people for whom cannabis may be harmful, and there's also a very specific aspect of cannabis, including the ratio of THC and CBD, that should be taken into account.
That being said, obviously there will always be people who use cannabis. If we want to decrease the burden associated with cannabis use, we have to be able to protect those who are vulnerable, but also be able to control what is in the substance and be able to actually make sure the messages sent to society in general are accurate, but also can be said clearly.
The question is how we could regulate to protect vulnerable people to make sure that...for the general population for which cannabis is not harmful, it would not necessarily prevent them from doing something that is harmful, but how we could protect those people and control what is in the substance. That question is obviously outside of my specific knowledge. What I can say from a clinical standpoint is that regulating and controlling what is in the substance is obviously not something that is done by drug dealers who sell the drug on the street, and it is not done by criminal organizations that would actually put the cannabis on the market. That's very clear to me.
The second point is for me to be able to conduct more accurate research on the specific effect of the different chemicals that can be found in cannabis. Also a very important thing for me is to differentiate therapeutic use from the law and regulations regarding cannabis use for recreational purposes.
Those are two very different reasons and topics which, in my opinion, are sometimes mixed together in the population, but also among politicians and even scientists.
