Patients struggling to pay for insulin

Cost of the drug in US has skyrocketed in past decade, drawing public outcry

When US Senator Bernie Sanders took a short bus trip across the US-Canada border last month, he wasn't alone.

About a dozen people with diabetes joined the Democratic presidential candidate on the bus from Detroit, Michigan, to Windsor, Ontario, to buy insulin at a Canadian pharmacy, just minutes from the border. A vial that one woman said could set her back $340 in the United States had cost her about one-tenth of that in Windsor.
