OTTAWA, June 10, 2013 /CNW/ - Canada's doctors worry that today's
announcement of new regulations to govern the use of medical marijuana
ignores the fact that there is no clinical evidence to back up its use
as a medical therapy.
This approach runs contrary to Canadians' position on this issue as
reported in an Ipsos Reid poll conducted for the CMA earlier this year.
The poll found that 85 per cent of Canadians believe that medical
marijuana should go through the same rigorous testing and approval as
Asking physicians to prescribe drugs that have not been clinically
tested runs contrary to their training and ethics. Expecting doctors to
write prescriptions for marijuana without the existence of such
evidence is akin to asking them to work blindfolded and potentially
jeopardize the safety of patients.
Marijuana is a complex substance with strains that vary greatly in power
and effect, but we have no information on potency, dosage or how it
interacts with other therapies. The beneficial effects of marijuana
have not been rigorously tested and it has a huge potential to cause
harm. With the federal government vacating its role, there is no one to
certify that the drug will not harm the patient.
Federal rules and regulations dictate that before a drug may be
prescribed, rigorous research and testing must be undertaken to
establish safety and efficacy - this research includes clinical trials.
As a result of the rigorous research requirements, physicians know how
much to prescribe, what the benefits are and what the side effects
could be. None of that information exists for marijuana. We don't even
know what is in the various strains of marijuana.
The Ipsos Reid poll also found that almost eight in 10 Canadians agreed
that Health Canada, as the body that approves prescription medicines
for safety and efficacy, should maintain its current role in
authorizing the use of medical marijuana for patients.
Patients would not want us to prescribe drugs for heart disease, cancer,
or any other illness without the scientific evidence to back those
drugs up. Why does the federal government want us to do so with
The use of medical marijuana has grown because there aren't better
treatments for people battling chronic pain. This is an area that
definitely needs greater attention. The federal government will not
help address this lack by abdicating its responsibility to protect the
health of Canadians.
Let me be clear that physicians are deeply concerned that many patients
have great difficulty in their battles with chronic pain. Clearly there
is a need for more effective pain treatments. The CMA has been asking
for years that marijuana be treated the same as any other drug and its
use backed up by research and clinical trials. The federal government
will not help address this lack of evidence by abdicating its
responsibility to protect the health of Canadians.
