Pharmacy customers in Alabama may soon receive a warning about imported medicines when they get their prescriptions filled.

More than 700 Alabama pharmacies are receiving posters and fliers as part of an education campaign launched in Montgomery by American and Canadian pharmacy officials.

Some U.S. citizens and local governments -- including the city of Montgomery -- have been ignoring a federal ban on drugs from Canada. They say the cost savings are too good to pass up.

But opponents claim drugs marketed from Canada may actually be made elsewhere because Canadian drug makers can't keep up with the growing demand.

They say drugs made outside Canada are not properly screened.

Campaign workers say they'll keep spreading their message even though Health and Human Services Secretary Tommy Thompson said it's inevitable that Congress will legalize imported drugs.
