JEFFERSON CITY, Mo. (AP) — Missouri House members have passed legislation that aims to crack down on methamphetamine by requiring prescriptions for some cold and allergy remedies containing pseudoephedrine.  The decongestant is a key ingredient in meth.

The prescription requirement would apply to solid tablets that contain the substance. Liquids and gel-caps could still be purchased without a prescription.

Missouri already requires pharmacies to keep pseudoephedrine remedies behind their counters and limits the amount customers can buy at one time. The state recently implemented an industry-funded electronic database to track purchases in real time.

The bill cleared the House on a vote of 86-64 Monday and went to the Senate. The legislative sessions ends Friday evening.
