I propose to give part of the answer and then turn it over to my colleague, Peter Brander, who can talk a little bit about our compliance enforcement approach that we have taken over the last number of years.
The challenge that we face as a regulator is you need to be evidence-based in terms of what you do and what your approach is. Obviously part of the evidence is the scientific work. That scientific work has truly just been emerging over the last number of years and it certainly hasn't caught up. I would say the prevalence of use in the market has well outpaced the state of the science.
I think it's also important to note that we do have a regulatory framework in place. We do have the Food and Drug Act. We can act and we have acted. Peter will be able to tell you a bit more of that story. We also have the consumer product safety framework. We've seen reports from abroad, but we haven't had reports here of exploding e-cigarettes, leaking cartridges, etc. We do have the regulatory authority to act. I think it's important to understand that there is a regulatory framework that allows us to take action today, but it's the touch that you want to take that relies on the science.
