How come the feds aren't raiding Phizer right now? The Associated Press reports: Narcotics are easily purchased over the Internet from U.S. pharmacies with no prescription, congressional investigators maintained Thursday at a Senate hearing on the dangers of buying medications online. Investigators said they purchased the painkiller hydrocodone from eight Web sites. "It seems that the key thing here is having your credit card," Robert Cramer, a senior investigator with the General Accounting Office, said. In no instances were GAO employees who posed as patients asked to see a doctor or provide a prescription, Cramer said. Despite safety concerns voiced by opponents of prescription drug imports, investigators said, however, they encountered few problems with medicines purchased from Canadian Web sites.
