CLAYTON, Mo. (AP) – St. Louis County has become the first jurisdiction in Missouri to adopt a program for monitoring the sale of prescription drugs, including opioids that can sometimes cause addictions and lead to heroin abuse.

The St. Louis Post-Dispatch reports that the county council voted unanimously Tuesday to enact the program. The vote came hours after the Missouri House gave initial approval to a bill that would establish a statewide database to track the dispensing of some prescription painkillers.

But the state bill could die in the Senate. Missouri is the only state without a monitoring program.

County Councilman Sam Page, an anesthesiologist and sponsor of the county bill, says drug dealers come to Missouri to get prescriptions filled due to the lack of monitoring.
