Mr. Speaker, when I look at the bill, I think of what happened in the past with the regulations that were set for the consumption of alcohol and driving. We went through a fairly rigorous process of determining over the years scientifically that it was .08, but we have seen movement now to a higher level of intolerance with alcohol content in the body. My riding has gone to .05. This has not been done through a process but through pressure rather than a scientific understanding of the nature of impairment.
With this particular bill, where we are dealing with a multitude of substances taken singularly and in combination, how do ensure that we are charging people who are actually impaired, in other words, providing incontrovertible evidence or even a standard of application that can give some surety to the courts and to our citizens who are human beings like all of us and may partake in one or other of the substances that are part of the common culture in Canada?
