Medicines containing pseudoephedrine--one of the main ingredients of meth--could soon be available by prescription only.
The Senate Judiciary Committee voted 6-5 to pass the legislation Thursday in an attempt to curb meth production.
It's the first hurdle of many to be passed in order to make some over-the-counter medicines prescription-only. The proposal will go to the full Senate next, where its chances are uncertain.
Over the past year, lawmakers have been debating about possible restrictions on sales of certain cold and allergy medicines containing the meth-making chemical.
A proposal like this one cleared the Judiciary Committee last year but never got a vote in the full Senate.
Senate Republican Floor Leader Robert Stivers II said Thursday he doesn't know if the measure has enough support to survive a floor vote.
