The Michigan Senate has voted to limit the sale of cold medicines in an effort to curb the number of meth labs sprouting up across the state.
The bill requires customers to show ID when they buy decongestants such as Sudafed that contain ephedrine or pseudoephedrine.
Pseudoephedrine is a key ingredient used to make methamphetamine.
The bill also would bar retailers from selling the products to anyone under age 18.
Stores couldn't sell more than two packages, or 48 tablets or capsules to a customer.
If stores do not keep the products behind the counter or in a locked case, they would have to keep a log listing every buyer's name and date of birth.
The bill now heads to the House.
