Are there any medical studies on trace amounts of Meth?

[William Hochstedler]

Personally, of all problems that a property might have, meth contamination, even when remediated scares me the most.  I'm finding more and more flippers and wholesalers who are pretty cavalier about remediated properties because we now have laws that have specific tolerances for trace amounts and disclosure requirements.

My concern is that unlike LBP and asbestos which have not been used for decades and are still the subject of law suits and other RE problems, meth, even in trace amounts, is airborne.

So my question is, does anyone know of any long-term multi-generational medical studies that justify these legal tolerances?  Or are they arbitrary numbers that make remediation possible without condemning properties?

It seems crazy to me that anyone can be so flippant about houses testing positive for hazmats without very much understanding about the long-term liabilities.  Other than not touching the property, is there any way to limit this liability when they find a causal link between trace meth exposure and, say, birth defects or cancer?

Thanks for any input.
