WASHINGTON (AP) - A study finds that drugs that are not supposed to be sold over the counter are sold over the Internet all too easily.
The report from Columbia University researchers finds that more than three-quarters of web sites that offer highly addictive medications, such as Oxycodone, do not require a prescription.
Of the 365 sites selling controlled substances online, Columbia researchers found 85 percent did not require a doctor's prescription.
The number of online establishments selling the drugs fell 37 percent from last year.
But researchers said the decline was likely due to law enforcement efforts to crack down on online drug trafficking.
The Senate earlier this year passed a bill that would explicitly ban the delivery of highly regulated drugs over the Internet without a prescription.
The bill is pending in the House.
