Record meth finds recorded in 2012

The Tarheel State broke a record in 2012, but it's not a good one.
North Carolina authorities found a record number of meth labs last year.
The North Carolina attorney general says agents found 460 labs in 2012.
That's up more than one hundred from 2011.
Authorities say most of those finds were one-pot labs.
North Carolina lawmakers are now looking into an electronic system used to track pseudoephedrine sales, which is a main ingredient in meth.
