Do You Have a Meth Problem? Know the Warning Signs
Methamphetamine contamination is invisible, odourless in low concentrations, and can persist in a property for years. Here’s how to recognise the warning signs and understand your risk and see if you have a meth problem.

Signs You May Have a Problem
These warning signs may indicate methamphetamine has been used or manufactured at a property. Even one sign warrants professional testing.
Strong Chemical Smells
Persistent chemical, ammonia, or solvent odours — especially in enclosed spaces like garages, sheds, or bathrooms — may indicate past manufacture.
Yellow or Brown Staining
Unexplained staining on walls, ceilings, vents, or around light switches can be residue from meth use or manufacturing.
Burn Marks & Foil Residue
Small burn marks on surfaces, foil with burn holes, or improvised pipes found on the property suggest meth use.
Modified or Blocked Venting
Unusual modifications to ventilation, covered windows, or blacked-out rooms may have been used to conceal manufacturing.
History of Drug Activity
Police activity, evictions for drug use, or reports from neighbours about suspicious behaviour increase the likelihood of contamination.
Unexplained Health Symptoms
Occupants experiencing headaches, nausea, skin irritation, or respiratory issues that resolve when they leave the property may indicate contamination.
Health Effects of Meth Contamination
Methamphetamine residue can be absorbed through skin contact, inhalation, or ingestion. Even at low levels, chronic exposure can cause serious health effects — especially in children, elderly, and people with respiratory conditions.
Short-term exposure symptoms include headaches, nausea, dizziness, eye irritation, and skin rashes. Long-term or high-level exposure can lead to more serious conditions including respiratory disease, neurological effects, and immune system disruption.
- Headaches and dizziness
- Nausea and vomiting
- Skin and eye irritation
- Respiratory issues and coughing
- Fatigue and difficulty concentrating
- Increased risk for children and vulnerable people

What to Do If You Suspect Contamination
Understand Your Results
Australian guidelines set 0.5μg/100cm² as the action level. Results above this require professional remediation before the property is safe to occupy.
