You don't need to be a meth head or sympathise with their stupidity to celebrate Sir Peter Gluckman's report on the risk they pose to houses. At long last someone has brought a sense of proportion to a question of public health and safety.
Gluckman has defied the excessive caution that rules so much of our lives today, casting aside the precautionary principle that says a lack of evidence of harm does not prove something is safe.
The Government's Chief Science Adviser has given Housing Minister Phil Twyford the finding Twyford wanted, enabling more state houses to be kept tenanted, but it was courageous nonetheless. Not because he has threatened the business of fumigating firms, those pose no risk to his reputation, unlike fellow scientists who assiduously promote the precautionary principle.
The morning after his report was published, an Australian professor was on the radio complaining that the report ignored case studies she had given him showing health effects from meth residue at lower levels than he was recommending as a threshold for concern. Gluckman replied that her studies were of houses used to cook the stuff, he was talking about the residue from smoking it.
If his report was refreshing to read, it was mild by comparison with the enthusiastic response from the Green Party, usually committed to the precautionary principle. "Hundreds of people have been unnecessarily turfed out of state homes and other houses because of scaremongering by people with vested interests," fumed co-leader Marama Davidson. "This has caused so much hardship for so many families with no good reason....."
