REIMPORTATION PLAN: Drug makers threaten sellers
Major drug companies are fighting any movement to let Americans buy prescription drugs from Canada with new ferocity, giving a preview of what may await Minnesota Gov. Tim Pawlenty's drug reimportation website.

Last month, officials from Pfizer Inc. warned Canadian drug wholesalers that they must refuse to ship to any Canadian pharmacy that sells medicines to Americans. If they don't, Pfizer warned, the wholesalers themselves would be cut off.
