Illicit drug contamination

Properties used for making or smoking illicit drugs, such as methamphetamine (meth, ice), or growing cannabis may be a contamination health risk to current and future occupants. The risk depends on the type of activity at the property.

Premises of concern include:

  • clandestine drug laboratories (clan lab): a house or area used to manufacture or ‘cook’ illicit drugs, especially meth
  • meth or illicit drug smoke house: a house used to smoke these drugs, but not manufacture them
  • grow house: a property used to grow an illegal crop of cannabis (marijuana) for sale

The Department of Health Illegal Drug Activity in Homes: Managing Risk (PDF 1MB) provides an overview on how to deal with these issues, particularly for owners or agents. Detailed guidance on the three contaminating activities and remediation processes are provided below. They all also include guidance on selecting qualified service providers.
