ST. LOUIS (AP) -- Methamphetamine lab seizures are on the rise in the nation's cities and suburbs, raising new concerns about a lethal drug that has long been the scourge of rural America.
Data and interviews from an investigation by The Associated Press found growing numbers of meth lab seizures in cities such as St. Louis, Kansas City, Mo., Nashville, Tenn., and Evansville, Ind. Authorities are also seeing evidence that inner-city gangs are becoming involved in meth production and distribution.
"No question about it - there are more labs in the urban areas," said Tom Farmer, coordinator of the Tennessee Methamphetamine and Pharmaceutical Task Force. "I'm seeing car fires from meth in urban areas now, more people getting burned."
The increase in labs is especially troubling because meth brought into the U.S. from Mexico also is becoming more pervasive in urban areas. The Associated Press reported in October that so-called Mexican "super labs" are upping production, making meth more pure and less expensive, and then using existing drug pipelines in big cities.
Data obtained by AP shows that homemade meth is on the rise in metropolitan areas, too.
- St. Louis County had just 30 lab seizures in 2009, but 83 through July 31, putting it on pace for 142 in 2012. The city of St. Louis had eight in 2009 and is on pace for 50 this year.
- Jackson County, Mo., (which includes Kansas City) had 21 seizures in 2009 and is on pace for 65 this year.
- Meth lab seizures have tripled in the Nashville area over the past two years. In one case in late 2011, a man and his girlfriend were accused of recruiting more than three dozen people, including some who were homeless, to visit multiple pharmacies and purchase the legal limit of cold pills containing pseudoephedrine, a key meth ingredient. The couple and 37 others were indicted.
- The Evansville, Ind., area has seen a more than 500 percent rise in meth seizures since 2010, with 82 in 2011.
Authorities cite numerous reasons for meth moving into cities, but chief among them is the rise in so-called "one-pot" or "shake-and-bake" meth.
In years past, meth was cooked in a makeshift lab. The strong ammonia-like smell carried over a wide area, so to avoid detection, meth had to be made in backwoods locations.
As laws limited the availability of pseudoephedrine, meth-makers adjusted with a faster process that creates smaller batches simply by combining ingredients - mixing cold pills with toxic substances such as battery acid or drain cleaner - in 2-liter soda bottles. Shake-and-bake meth can be made quickly with little odor in a home, apartment, hotel, even a car.
"Bad guys have figured it out," said Rusty Payne of the federal Drug Enforcement Agency. "You don't have to be as clandestine - you don't have to be in rural country to lay low."
Niki Crawford, who heads the meth suppression team in Indiana, said that with shake-and-bake labs, "the odors are not as strong. And they're just so portable. We find them in backpacks and gym bags."
And inside stores: A woman was arrested inside a St. Louis County Wal-Mart earlier this year with a meth-filled soda bottle in her coat pocket.
Another reason for the rise in urban meth is a process known among law enforcement as "smurfing" -the abundance of pharmacies in cities attracts meth-makers from surrounding rural areas, who can bring in friends to help purchase pseudoephedrine pills.
"We know the fuel for domestic labs is pseudoephedrine," Farmer said. "The source for that is pharmacies and the majority of pharmacies are in urban areas."
Farmer also has seen an increase in meth activity involving inner-city Tennessee gangs, which tend to be better-organized than rural cookers when it comes to marketing and selling the drug. For the most part, the gang members work as smurfers, though Farmer worries they'll eventually become involved in the manufacture and distribution of the drug. Sometimes, gang members and meth-makers first connect while in prison.
"They see there's a market there to make money off of pseudoephedrine," Farmer said. "Pseudoephedrine has become as good as currency."
Missouri State Highway Patrol statistics are indicative of the growing urban concern: All four of the top meth counties in Missouri were in the metropolitan St. Louis area - Jefferson, St. Charles, St. Louis and Franklin.
Ed Begley, a St. Louis County meth detective, said the drug is attracting users from all socio-economic levels.
"Lower class all the way up to upper middle class," Begley said. "We've even had retired folks who have become addicted. It's a brutal drug."
