Meth contamination can happen when someone smokes or makes methamphetamine (meth) inside a building. Meth smoke can leave residue on walls, counters, floors, furniture, and other items. The residue can also spread from one surface to another.
How People Can Be Exposed
People may be exposed to meth when they:
- Breathe secondhand smoke while someone is smoking meth.
- Touch a contaminated surface and then touch their mouth.
- Health concerns are more likely when someone has repeated or long-term contact with meth contamination, especially inside a home or other enclosed space.
Who Is Most at Risk?
Anyone can have symptoms from meth exposure, but some people may be at a higher risk, including:
- Infants and young children
- People who are pregnant
- People with weakened immune systems
- Meth leaves the body quickly. Health concerns from contaminated surfaces are more likely with repeated or long-term exposure.
