Washington’s Pierce County is among the top 10 in the U.S. for the number of contaminated meth lab sites found in the past eight years, according to the Drug Enforcement Administration. 

CNN created an interactive map which reflects data collected by the DEA's National Clandestine Laboratory Register between 2004 and 2012. The data includes all meth incidents including found labs, dumpsites, and seizures of chemicals and glassware.

If you’re a fan of the television series "Breaking Bad" then you know, in the words of Walter White,  that making methamphetamines "is just basic chemistry."

And some of the key chemical ingredients of meth are found in over the counter cold, flu and allergy medications which contain pseudoephedrine and ephedrine. That’s why the Washington State Board of Pharmacy is implementing a new electronic reporting system that will monitor purchases of these medications in real time.
