Mar 18, 2003 — As the cost of prescription drugs skyrockets, senior citizens who need them to survive are increasingly looking North. The Canadian International Pharmacy Association estimates more than a million Americans bought their drugs in Canada last year. They can cost a third the price of the same drug sold in the U.S. The U.S. Food and Drug Administration is vowing to crack down on the practice. One of the world's largest pharmaceutical companies, GlaxoSmithKline, has stopped selling to Canadian pharmacies that do business with Americans. In response, senior citizen groups across the country are boycotting some of Glaxo's products. David Sommerstein reports on one such protest in Potsdam.
