Meth houses stay contaminated for years

New research has found current methods of sampling don’t clearly indicate the extent of drug contamination inside houses.





Why This Matters: Drug contamination in houses poses a serious threat to health.




The Breaking Bad movie El Camino story line focusing on drug production is more relevant than ever- with a new study revealing methamphetamine contamination in houses is a public health problem around the world.


Flinders University researchers – Jackie Wright, Stewart Walker and  Kirstin Ross – analysed the contamination levels in everyday household items from a home suspected to have previously been used for cooking methamphetamine, to determine whether surface wipe samples can adequately establish contamination levels and define health risks.


The findings are published in the International Journal of Environmental Research and Public Health.

The hidden danger is contamination inside objects


The researchers explain while sampling commonly focuses on the collection of surface wipes, it’s difficult to understand the risk to inhabitants because those samples don’t indicate contamination levels inside objects.


“Our results demonstrate that methamphetamine has continued to mobilise after manufacture when the property was under new ownership for a period exceeding five years,” explains Ross.


“This suggests that the methamphetamine is not breaking down or being removed and is constantly transferred from contaminated to non-contaminated objects.”


The house that the researchers tested was suspected to be a premises used to cook methamphetamine. It was cleaned up and sold to new owners who lived in it for several years before the house was left unattended.


“Although the time since the cooking had taken place was significant, the levels of contamination were extremely high in both household items that were part of the house when cooking was taking place (blinds, carpets, walls, etc.) and also in articles brought to the house post-cooking (rugs, toys, beds, etc.).”


Current methods don’t detect the extent of contamination


The results raise questions about whether current surface detection methods allow people living inside a former meth house to understand the extent of contamination, not only on surfaces but also within building materials and items they’re exposed to on a daily basis.


“The most significant mass of methamphetamine was reported to be within the blinds. These are plastic blinds that were present when manufacture was suspected to have been undertaken. This is consistent with observations from other properties where higher levels of methamphetamine are present in materials such as PVC, polyurethane and stained and varnished timbers.”


“Without fully understanding the extent of contamination it’s difficult to ensure the correct and most effective remedial approaches are taken so occupants can safely live inside a property which was previously used to produce methamphetamine.”
