I appreciate your bringing up the question about access because it is an important issue as we discuss prescription drugs. Canada shares the distinction with the United States of being one of the only developed countries not to have universal pharmaceutical insurance coverage. So Canadians in fact face greater financial barriers to filling prescriptions than our comparable populations in many other countries, except for the United States.
I think this is an important issue because it may in fact lead some people to use over-the-counter remedies or other mechanisms that may be less rigorously assessed, or, at least as I think you're asking, that may be below the radar, and this is an important issue. One of the things I think the federal government might do in this domain is to ensure that we are adequately conducting surveys and collecting information about the population's use of these over-the-counter medicines and about their use of natural and homeopathic treatments.
That I think could be done through expanding, for instance, the Canadian community health survey, run by Statistics Canada, or through other mechanisms. So there are possibilities for bringing that information into this research realm so we can better understand it.
