OKLAHOMA CITY (AP) _ A new federal study shows the drop in meth labs in Oklahoma from 2004 to 2005 was the largest decrease in the nation.
The report released by the Drug Enforcement Agency's El Paso Intelligence Center shows the number of meth labs decreased more than 67 percent during that time.
The study shows the number of drug labs raided, found abandoned or found dumped dropped from one-thousand-58 in 2003, to 667 in 2004 to 217 in 2005.
Oklahoma enacted a law in April 2004 restricting the sale of pseudoephedrine _ a key ingredient in making methamphetamine. The law took effect in April 2004.
