As long as Canadians can get prescription drugs cheaper than their southern neighbors there are likely to be those in the U.S. who want to import them. Congress recently took up the issue once again and the pundits addressed the issues of free trade and big pharma.

David Sirota accuses senators from both sides of the aisle of hypocrisy. While officially rallying for free trade they're preventing millions of Americans from benefiting from it by importing safe FDA-approved medications.

Roger Bate defends the pharmaceutical companies' need to charge different prices in different countries to fund drug development and maintain presence in Third World countries to monitor drug response "A tiered model, based on ability to pay, is optimal—but will only work if the industry stands up for itself."

Kimberly Strassel argues that Americans don’t really want Canadian drugs. “Still,” she says, “don't expect the political caterwauling over imports to go away any time soon. There's still too much political upside to talking up a program that few Americans really want to use.”
