A multistate registry of pseudoephedrine sales that Oklahoma joined blocked up to 90,000 sales of the drug used to make methamphetamine last year, according to the Oklahoma Bureau of Narcotics.
Proponents of Oklahoma's decision to link its pseudoephedrine database with those in neighboring states say it restricts the interstate trafficking of the drug, which is found in many cold and allergy medications.
"They won't be able to just buy it here in Oklahoma, hit their daily limit, turn around and drive to Texas, Arkansas, Missouri or Kansas and do the same thing," said Mark Woodward, spokesman for the Oklahoma Bureau of Narcotics.
Authorities shut down 410 meth labs in the state in 2013, compared with 830 meth labs shut down in 2012, before the law went into effect, Oklahoma City television station KOKH reported (http://bit.ly/1fFRhZ7 ).
"It's really cut the access to pseudoephedrine out of criminals' hands," said Oklahoma Sen. Clark Jolley, R-Edmond, who helped write the measure.
Oklahoma previously enacted laws that limited the amount of pseudoephedrine that a person can buy, but Jolley said many found a way to get around the law.
"Criminals are always going to find a way to figure out a way to build a better mousetrap and try to figure out ways to avoid the things we put in place to block them from being able to break the law," Jolley said.
The Oklahoma Bureau of Narcotics estimated that last year, the multistate registry blocked about 70,000 to 90,000 sales of the drug in the states that take part in it.
