I am sympathetic to the points made. It is for that reason, and because of public concern and the kind of issues that have been raised, that despite the fact that what we know so far is that there is a probable but weak causal link, we have promoted the FRANK campaign, which has the slogan, "cannabis can mess with your mind", and we will continue to do that. Of course, while it is true that cannabis use is declining, the use of more potent cannabis such as skunk is increasing, and we are aware of that. We will continue our research and continue providing messages and information to the public.
