The regulation process is one that's used in other countries, including the United Kingdom. The science is rapidly evolving with respect to this. There is a great deal of research going on. We rely on the Drugs and Driving Committee for its advice. It examined five nanograms and two nanograms, the pros and cons of both of those. It picked five nanograms because that's what's in Colorado and picked two nanograms because that's what's in the United Kingdom. There are pros and cons to both of them. The government, based upon that scientific advice and its own views, decided to propose two levels. It made that clear. It'll have to be put in regulations eventually. The five-nanogram level is, according to the DDC, much more likely to be certain of impairment. The two-nanogram level is a public safety consideration.
The reason for regulations is that, frankly, as the science evolves and as the DDC has to opportunity to consider more and more drugs—which we hope it will do in the future—it will be difficult to come back to Parliament every time to amend the Criminal Code.
