This reminds me of the radon hysteria in Europe - but at least the meth tests are not compulsory yet (might come to that as well)...
Radon actually can be a real threat. (In some parts of Europe it appears that ground-floor readings are well in excess of WHO guidelines). I'm not sure if there was perhaps hysteria in places where levels were typically low.
Well, meth can be a real threat as well especially in former meth lab houses. You still have to have a radon test before building any new house in Europe.
If you read the above press release, the chance of meth tests (and huge cost of subsequent decontamination) being compulsory should be close to zero - unless the tenants were running a meth lab.
That's a good news. Though you can only identify meth labs which were found out...
