There are dozens of Web sites selling narcotics in the United States, with scores more operating offshore. Federal prosecutors have shut Web sites, filed indictments and won guilty pleas from several owners. But it often takes years to prove a case. In the meantime, the pills move.
For each site closed, "two or three more open," said Jennifer Bolen, a former federal prosecutor in Knoxville, Tenn. "It is so easy for them to close down a site one day and open a new one the next."
Some Web sites have dozens or even hundreds of affiliate sites. Others are designed to appear as though they are headquartered in the United States when they are really offshore, in such places as Namibia, Thailand and Sri Lanka. The growing numbers of foreign online pharmacies operate with near impunity. The Food and Drug Administration's strongest recourse is to send a warning letter, which usually is ignored.
"As an investigator, it's incredibly frustrating," said Robert J. West, a special agent with the FDA's Office of Criminal Investigations. "All we can do is bang away and try to draw attention to what these guys are doing. Right now, I don't think people have any idea how widespread or dangerous this is."
