Tennessee saw a rise in methamphetamine seizures in 2008.
Reports show that police seized just fewer than 550 labs through September 2008, more than a 20% increase since 2007.
According to drug task force leaders, meth manufacturing is changing as people find alternative ways of making the product because of a crack down in police control and legislation.
Local manufacturers are making meth by using people who shop in groups to buy large amounts of pseudoephedrine, which is used to make the drug.
Most arrests come from those sales.
