A St. Louis County town has passed a law aimed at assuring those who buy or rent a home that it is methamphetamine-free.

The St. Louis Post-Dispatch reports that Crestwood recently passed a law requiring the owner of any structure that housed a meth lab to thoroughly clean it before it can be sold or rented.

Pollution from a meth lab is sometimes so bad that a home has to be demolished. Experts say the chemicals from the drug get into the air and settle on curtains, the floor and furniture. Breathing those chemicals can cause illness.
