(KMOV) -- A new law goes into effect today restricting the purchase of medicine containing Ephedrine and Pseudoehedrine in St. Charles County.
The law now mandates consumers will need a doctor's prescription note to purchase medicine containing the two drugs.
The County council passed a bill on July 25, 2011 that regulates the delivering for the drugs due to their direct role as methamphetamine precursors.
Authorities in St. Charles county say the new law will help deputies fight the increasing meth problem in the area.
In 2010, the Sheriff's Department reported busting 92 meth labs in St. Charles County and so far this year, almost 100 meth labs have already been discovered and shut down.
