Updated 2:14 p.m. with a correction issued by the Associated Press. Corrects Missouri figure to "just more than 2,000," not "nearly 3,000."
An Associated Press survey of the nation's top methamphetamine-producing states shows national lab seizures rose again last year - and Missouri is, again, at the top of the list.
The survey confirmed that Missouri regained the top spot for lab seizures in 2011 with just more than 2,000 busts. It also found that Tennessee came in second with almost 1,700, followed by Indiana, Kentucky and Oklahoma.
