Four of the state's top 10 sellers of pseudoephedrine are located in Kanawha County -- three Rite Aid stores and the Southridge Walmart, according to the report.
This year, law enforcement agencies in Kanawha County, which has West Virginia's largest population, have busted 120 meth labs, five times more than in any other county.
Two Wood County Walmart stores -- in Vienna and Parkersburg -- also finished in the top 10 for pseudoephedrine sales. Wood County has reported 25 meth lab seizures -- the second-highest total in the state.
Officers in Nicholas County -- where the Summersville Walmart is located -- have discovered 10 meth labs since January, according to State Police data.
High pseudoephedrine sales, though, don't always correlate to large numbers of meth-lab seizures.
The Clarksburg Walmart and the Star City CVS near Morgantown reported the sixth-highest and 10th-highest numbers of pseudoephedrine boxes sold. Harrison County officers have seized three meth labs this year, while Monongalia authorities responded to only one clandestine lab. The Logan Walmart also ranked in the top 10 for pseudoephedrine sales, but Logan County has reported only two meth labs this year.
The Southridge Walmart's pseudoephedrine sales have tripled since January, according to a previous report limited to Kanawha County store sales.
Foster said Walmart's 1,851-box total in August should raise a red flag. By comparison, a Tennessee task force recently released a report that listed pseudoephedrine sales in that state. A Walgreen's in Memphis topped the list with 1,435 boxes sold in August.
"The Southridge Walmart total is just unbelievable," Foster said. "It's a real head-scratcher. You have to assume a lot of that [pseudoephedrine] is not being used to treat colds and congestion."
In response to questions about the pseudoephedrine sales report, Walmart spokeswoman Danit Marquardt said Wednesday that the retail chain is "committed to quality patient care and social responsibility. We work with government officials, law enforcement and others to serve patients who benefit from these products while protecting against their potential misuse."
West Virginia's NPLEx report of pseudoephedrine sales counts total transactions -- and does not include blocked sales. The electronic system blocks purchases when people try to exceed monthly and yearly limits set by state law. NPLEx has blocked about 4 percent of the West Virginia's total pseudoephedrine sales this year.
In West Virginia, pharmacies keep pseudoephedrine products behind the counter. Customers must show a photo ID to purchase the decongestant.
West Virginia law enforcement agencies have reported 373 meth lab busts this year, the most in state history.
