Missouri’s year-old law limiting access to a key ingredient for making methamphetamine is working…..but it’s hard to say it has cut down on the meth supplies in the state or the number of meth users. The highway patrol has seen a 46 percent decline in the number of meth incidents—anything meth-related for which first responders or law officers would be called out. The new law requires people buying ephedrine or pseudo-ephedrine products to identify themselves and enter their names into a database. Spokesman Jason Clark with the Highway Patrol’s Criminal Division thinks the law is one reason the number of meth lab seizures in Missouri has declined, although more than 12-hundred have been found this year and Missouri is still number one in the nation in that category. It’s not something the state is proud of, but he says the important thing is the big reduction in the number of labs. But meth users have to get their stuff somehow. He says troopers have noticed a marked increase in the amount of meth being imported from other states. He says Missouri’s law has gone after the mom-and-pop operations, for the most part. But with them increasingly out of business, outside meth makers are seeing Missouri has fertile trading territory.
