States are increasingly passing laws to establish electronic databases to track pseudoephedrine purchases to crack down on meth drug labs; Virginia, Indiana, Missouri, and Alabama have already implemented such databases, while large retail chains like Walmart, CVS, and Rite Aid maintain their own electronic databases; in 2008, 850,000 Americans were found to abuse meth; in 2009, the DEA discovered more than 10,000 meth labs, down from a high of more than 19,000 in 2004
