As regular readers know, I am against drug reimportation laws (on general principles, not because of a fear of "dangerous" drugs coming out of Canada). But a report shows that drugs whose patents have expired can be purchased here in the US for less than the Canadian brand-name drugs, and they are even less than Canadian generics (with the exception of a diabetes drug, whose American generic was significantly higher than the Canadian equivalent). This was a small study (it covered only seven drugs, although they were the best-selling drugs with generic equivalents) and it did not cover drugs still under a patent, but the results are interesting nonetheless.
