Chief science advisor Sir Peter Gluckman has found there is no evidence that contamination from smoking meth poses a risk to health.
• Methamphetamine is a powerful, highly addictive stimulant used illicitly in New Zealand and around the world. It is obtained either through smuggling into the country, or by being manufactured locally in clandestine laboratories (meth labs). These meth labs may be found in residential dwellings, commercial accommodation, and even vehicles.
• A dwelling can become contaminated with methamphetamine residues if the drug is manufactured or smoked within it. Smoking usually results in much lower residue levels compared with manufacture. . .
• Passive, third-hand exposure to methamphetamine can arise through residing in a dwelling previously used as a clandestine meth lab, or where a significant amount of methamphetamine has been smoked. Former meth labs generally have relatively high levels of methamphetamine residue on sampled surfaces (levels greater than 30 μg of methamphetamine per 100 cm2 surface area are thought to be indicative of manufacturing activity). There is some evidence for adverse physiological and behavioural symptoms associated with third-hand exposure to former meth labs that used solvent-based production methods, but these symptoms mostly relate to the other toxic chemicals in the environment released during the manufacturing process, rather than to methamphetamine itself.
• However, there are no published (or robust, unpublished) data relating to health risks of residing in a dwelling formerly used only for smoking methamphetamine. Yet, given the relatively low number of confirmed meth labs found, and the very low average levels of methamphetamine found in most houses that test positive for the drug, most New Zealanders will only ever encounter very low levels of residue that are the result of methamphetamine use. . .
In the past meth users were evicted from state houses, now Housing NZ will let meth users stay in their houses and try to get them help.
Housing Minister Phil Twyford said Housing New Zealand is a landlord for some of the most vulnerable people in the country.
He said if the agency discovers a tenant is smoking meth, it will try to help them. . .
He said the response from Housing NZ now was to treat people using meth as a health issue.
“Under the old government the policy was to make that person homeless – the worst possible thing that you could do.
“If someone’s got a drug addiction problem, you couldn’t do anything more calculated than to make them vulnerable to greater risk in their health, and in fact incurring greater expense to the taxpayer than throwing them out of their home and making them homeless.
“Housing New Zealand is a landlord … they’re not the police.
There is merit in treating drug use as a health issue and trying to find help for addicts.
But I am concerned that this policy sends a message it’s fine to smoke in other people’s houses.
All landlords have the right to tell tenants they can’t smoke anything – legal or illegal – in their houses.
We have a strict no smoking rule in all our farm houses. One of our sharemilkers goes further, telling his staff the whole farm is smoke-free.
Property owners and employers have a right to do that.
Another thing to remember is that no evidence of harm is not the same as proof of no harm.
Science is rarely settled and regardless of what the research has found, I wouldn’t want to live in a house where people had been smoking meth.
