What are the common signs of a meth lab?

• Strong odours similar to fingernail polish, cat urine, or ammonia
• Iodine or chemical-stained fixtures in kitchen and bathroom.
• Excessive rubbish that includes large amounts of discarded containers/packaging for cold medicine containing ephedrine/pseudoephedrine, drain cleaner, antifreeze, denatured alcohol, lantern fuel, and red-stained coffee filters.
• Bottles or jars with glass tubing
• Stained soil or dead vegetation
• Black plastic over windows

However, there may be no obvious signs that meth has been used or manufactured. Only a Narcotect test kit will alert you to potential contamination.
