Meth Lab Materials
Items that may indicate a meth lab:
- Aluminum foil
- Measuring cups
- Antifreeze containers
- Papers, notes, “recipes”
- Blenders
- Plastic storage containers
- Coffee filters (especially red/pink-stained)
- Duct tape
- Rubber tubing/gloves
- Funnels
- Thermometers
- Glassware
- Thermos bottles and propane tanks (used to steal anhydrous ammonia from larger tanks)
- Heat sources, like hotplates or microwaves
Many of these are common every day household appliances or materials. Taken in isolation they should not be a cause for alarm. Taken together, however, they point to suspicious activity or the presence of a meth lab.
Substances that may indicate a meth lab:
- Acetone
- Isopropyl or rubbing alcohol
