Identification of a Meth Lab

What are the components of a meth lab?


How is meth manufactured?

EPA's Voluntary Guidelines for Methamphetamine Laboratory Cleanup provides technical guidance for state and local personnel responsible for methamphetamine (meth) lab cleanup. The Guidelines are based on an extensive review of the best available science and practices and addresses general cleanup activities, identifies best practices for specific items or materials, discusses sampling procedures, and provides additional technical resources. These guidelines explain the four methods used to manufacture methamphetamine:

  1. Nazi/Birch Reduction
  2. Red Phosphorus/Hydriodic Acid
  3. P2P Amalgam
  4. One-Pot

The one most currently found in Indiana is the one pot.


What does a meth lab look like?

  • Abnormal amounts of chemical products such as drain cleaner, cold packs, pseudoephedrine tablets, or lithium batteries
  • Strong or irritating pungent odors (Ammonia/Solvents)
  • Distinctive trash such as pseudoephedrine "bubble" packaging, battery casings from disassembled lithium batteries, and HCL generators (plastic bottles with tubing)
  • Containers altered from their original use, i.e.,  gas tanks (like the kind attached to a grill) with retrofitted valves
  • Spent one pot reactions with different powders, liquids, and pieces inside disposable containers, i.e., plastic drink bottles
