TALLAHASSEE, Fla. (AP) - A new law that went into effect due to veto override is delaying rules to crack down on "pill mills" that cater to drug dealers and addicts.

The St. Petersburg Times and Miami Herald reported Wednesday that the rules were to go into effect Sunday for most pain clinics, but the law has put them on hold.

It requires legislative approval of administrative rules that have at least a $1 million adverse economic effect over five years. The rules are being reviewed and if they meet that criteria it'll probably be March before lawmakers can act.

Gov. Charlie Crist vetoed the bill, but he was overridden at a special session Nov. 16.

Lax regulation has made Florida a major supplier of prescription drugs for illicit use.
