Methamphetamine (commonly called “P” in New Zealand) residue can persist in a house for a significant period, as the chemicals used in meth production can adhere to surfaces and linger in the environment.
The duration that meth residue remains in a house depends on various factors, including the extent of meth use or production, ventilation, cleaning measures, and the specific surfaces involved.
Here are some general guidelines:
1. Active Meth Labs: If a house has been used as an active methamphetamine lab, the contamination level can be particularly high. In such cases, the residue can persist for an extended period, potentially years, without proper decontamination.
2. Meth Use: If the house has been used for meth consumption, the level of residue is generally lower than in active labs but can still be present. Residue from meth smoking or handling can accumulate on surfaces such as walls, ceilings, carpets, furniture, and ventilation systems. The duration of residue depends on the frequency and duration of use.
3. Ventilation and Air Circulation: Proper ventilation and air circulation can help reduce the persistence of meth residue. Increased airflow can aid in dissipating the chemicals and lowering contamination levels. Conversely, inadequate ventilation can contribute to the prolonged presence of meth residue.
4. Cleaning and Decontamination: Thorough cleaning and decontamination are essential to remove meth residue effectively. Professional cleaning companies specializing in methamphetamine decontamination can use specialized equipment, techniques, and cleaning agents to eliminate or reduce contamination levels. The effectiveness of the cleaning process significantly impacts how long the residue remains in the house.
5. Porous vs. Non-Porous Surfaces: Methamphetamine residue tends to adhere more strongly to porous surfaces, such as carpets, upholstery, drywall, or insulation. Non-porous surfaces like glass, metal, or laminate may retain less residue and be easier to clean. The type of surface influences the persistence of meth residue. Be sure to check your kitchen surfaces.
It’s important to note that methamphetamine residue poses potential health risks, especially if it is present at high levels.
Prolonged exposure to residue can cause various health problems.
If you suspect a property may have methamphetamine contamination, it is advisable to consult with professionals trained in meth cleanup and decontamination to assess the situation and take appropriate remediation measures.
