 A proposal called the Safe Importation Action Plan would allow states, wholesalers and pharmacies, but not patients, to buy drugs from Canada.All online pharmacies sell through the Internet but must ship the product usually via mail.The selling of many class (schedule) drugs without a valid prescription (also called Rx-only drugs or legend drugs) is illegal, and companies shipping them by mail can be prosecuted for mail fraud (Postal Inspection Service) as well as being investigated and federally charged by the DEA, IRS, Homeland Security, Food and Drug Administration's Office of Criminal Investigations, Department of Justice, INTERPOL, and the U.S. Immigration and Customs Enforcement (ICE), and it is common practice for many agencies to jointly investigate alleged crimes.
