In response to Florida's ongoing prescription-drug abuse problems, the Drug Enforcement Administration has launched a pill-mill tip line.

Law-enforcement officers throughout the state continue to investigate rogue doctors who dole out powerful, addictive drugs to people who don't have a true, medical need for the pills.

The DEA said Monday that undercover law-enforcement officers have made hundreds of purchases of prescription drugs from such doctors in South Florida over the last year.

DEA's 24-hour tip line is 888-954-4662. Tips can also be sent to Florida.Pill.Mill.Tips@USDOJ.GOV.

Callers should leave their contact information and the names of any doctors or clinics they are calling about.
