Thank you for the question.
It is true that when it comes to dried marijuana, the regime that exists is as a result of various court decisions over the years, and it is true that dried marijuana has not gone through the clinical trials, etc., and the rigorous process that is required for any other prescription medication in this country.
I will just mention that there are two drugs that contain extracts or derivatives of cannabis that have been through that process and are approved under the Food and Drugs Act. They're called Sativex and Cesamet. So there are cannabis-containing products that are available, that have gone through the usual process.
When it comes to dried marijuana, Health Canada has prepared, with the assistance of an expert advisory committee, a review of the evidence that does exist—the various studies and some limited clinical trials—in an attempt to offer to health care practitioners what information does exist, but it is very limited.
