Medical marijuana shows promise for pain
After all the usual and proper medical approaches did nothing for her pain, Cheryl Campbell, a nurse and mother, says she finally built up the courage to ask her doctor, "How do you feel about prescribing me marijuana?"
The 30-year-old Ottawa woman suffers from fibromyalgia and chronic fatigue syndrome. Her pain is body-wide - a constant, sometimes stabbing ache in her back, hips, knees, shoulders and virtually every joint. Doctors once put her on morphine. It cut the pain, but she couldn't function. She says her mind felt so heavy with fog she couldn't carry on a conversation.
She's been using marijuana for pain for two years; she has a federal licence to possess it. She says it helps her sleep at night. In the morning, it helps ease the stiffness in her hips and back enough that she can make it into the shower.
Campbell says she owes her ability to get through each day to a drug that critics condemn, especially when it's smoked - which is how most of the thou-sands of Canadians who self-medicate with pot prefer to take it. The U.S. Drug Enforcement Agency was unequivocal earlier this year: Smoked marijuana is not medicine, and it's not safe.
"No matter what medical condition has been studied," the agency ruled, "other drugs already approved by the [U.S. Food and Drug Administration] have been proven to be safer than smoked marijuana."
But research into medicinal marijuana is undergoing a surge of interest, with more evidence emerging not only of its ability to ease human suffering, but also of its apparent safety.
Some say cannabis may be less toxic to humans than over-the-counter pain relievers.
Four small but scientifically controlled experiments in recent years have concluded that smoked cannabis can provide moderate relief from chronic, severe non-cancer pain - including HIV-related nerve pain and post-traumatic neuropathy, a dreaded condition that can follow an injury or medical procedure. Both are notoriously resistant to conventional treatments.
