CHATTANOOGA, Tenn. -

Franklin County is trying to become the first county in the state to require prescriptions for pseudoephedrine-based cold medicines as a way to fight methamphetamine production.

The Chattanooga Times Free Press reports Cowan, Decherd and Estill Springs are the remaining municipalities set to pass local rules on the purchase of these drugs, which are already required to be placed behind the pharmacy counter statewide. The medicines are a primary ingredient in the production of meth.

Franklin County Sheriff Tim Fuller said the General Assembly couldn't pass a statewide law requiring a prescription, but local municipalities can put guidelines on how they can be sold. Fuller said he was challenging the local communities to take a stand to stop meth production and abuse.
