Amy Wiebe, pharmacy manager at the Saskatoon City Hospital, said she held biases about medical pot in the past. "There's so much stigma attached to it, and I had a pretty big bias against it," Wiebe said. "But the more I learned, the more I was like, 'OK maybe there is something to this.' " Speaking to the Canadian Pharmacists Association in Calgary, Wiebe said while the benefits of properly prescribed medical marijuana is clear, there are many aspects of treatment that have to be fine tuned. Her speech, which called marijuana a 'moving target,' focused on how marijuana and the political and medical landscape itself is changing. In 2001, there were about 500 medical marijuana users, and Wiebe said some estimates set the figure at 70,000 users now. Meanwhile, the federal government next year is to introduce legislation to legalized cannabis in Canada. Wiebe noted the potency of the drug has changed as well over the decades. In the 1960s, the potency of THC, the main component of marijuana that causes euphoric effects, was about 1-2%, while now there are strains available with around 25% potency. Now, Wiebe said, the main challenge physicians face is to find the perfect sweet spot of how large prescription doses should be. She said her advice on that is to "start slow, go slow," using low doses at first and incrementally increasing to find the right sweet spot. "We know that sometimes there's a fine line between what's going to work versus what's going to cause somebody to have negative effects that'll outweigh the benefits," she said. Wiebe said most of cannabis' negative effects are short-term ones that wear off as patients come down from the drug. - --- MAP posted-by: Matt
