Buying a house is one of those big, exciting moments in our lives which we'll always remember.
But some homeowners find something about their home they surely would like to forget.
Your home may have contained a meth lab.
Long term exposure to harmful chemicals is called chronic toxicity.
And you might think people who are high at risk are meth cooks, but those toxins can stay in the house long after a meth lab shuts down.
"They were cooking meth out here for years" are words you probably don't expect to hear from your new neighbors when you've just moved into a new home.
Meth doesn't go away when the users or makers of it leave the home.
Cindi Newcomb of Santi Kleen, cleans up meth sites.
She tells us unless you get your home tested, you could be exposing yourself to toxic chemicals and not even know it.
"What we hear from people is 'I was in the house and all of a sudden, I got a headache or I couldn't sleep. I was in there for three or four days and I just couldn't seem to settle down and get to sleep. I had a bad taste in my mouth.' Pretty mild symptoms but on the other had pretty irritating," Newcomb said.
"If they're going to test for mold, or radon or lead or have home inspection, for a couple bucks more they can add one more thing to it and they can at least avoid the heart ache of buying a house that's going to make them sick," Newcomb added.
Children are at high risk of chronic toxicity, especially toddlers because they like to touch things or crawl around.
