INDIANAPOLIS (AP) — A newspaper investigation has determined home inspectors often don’t test for methamphetamine contamination, which can lead to a variety of health problems, even though Indiana leads the nation in meth busts.

The Indianapolis Star reports experts say thousands of homes across the state likely have been contaminated by residents making or using the drug. But many homeowners aren’t aware of the risk and don’t know meth can be detected through several hundred dollars’ worth of testing.

Although the state’s real estate disclosure form asks sellers specifically about the meth contamination, the law doesn’t require real estate agents to verify their answer through testing, because it’s not part of a standard pre-sale home inspection.

The presence of meth in a home can lead to nausea, diarrhea, body aches, coughing and breathing issues.
