Cold medicines containing pseudoephedrine.

(Indianapolis, Ind.) - New federal data is showing efforts to stop meth production by electronic tracking of pseudoephedrine sales have not worked, and Indiana lawmakers are now considering a new weapon.

The Terre Haute Tribune-Star reports state Senator Tim Skinner and state Representative Clyde Kersey are pushing legislation classifying pseudoephedrine as a controlled substance. 

That would mean in order to get the cold medicine, you'll need a prescription. 

Mississippi and Oregon have both made such a change in the law. Oregon saw meth lab busts fall from 473 in 2003 to just 12 in 2010 after the state enacted a law requiring a prescription for pseudoephedrine products in 2006.

Indiana State Police reported 1,343 meth labs were found across the state in 2009.
