I think there may be a meth lab in my neighborhood; what are the indicators to help me know if this is the case?

The Department of Health states: Clandestine labs are extremely dangerous. Many of the chemicals found in these labs are corrosive or flammable. The vapors that are evolved from chemical reactions attack mucous membranes, skin, eyes, and respiratory tract. Some chemicals will react with water or other chemicals and cause a fire or explosion. 

Clandestine lab indicators:

• A large amount of cold tablet containers that list Ephedrine or Pseudoephedrine as
  ingredients.
  
• Jars containing clear liquid with a white colored solid on the bottom.
  
• Jars labeled as containing Iodine or dark shiny metallic purple crystals inside of jars.
  
• Jars labeled as containing Red Phosphorus or a fine dark red or purple powder.
  
• Coffee filters containing a white pasty substance, a dark red sludge, or small amounts of
  shiny white crystals.
  
• Bottles labeled as containing Sulfuric Acid or Hydrochloric Acid. Bottles or jars with rubber
  tubing attached.
  
• Glass cookware or frying pans containing a powdery residue.
  
• An unusually large number of cans of Coleman Fuel, paint thinner, acetone, starting fluid,
  Red Devil Lye, and drain cleaners containing Sulfuric Acid or bottles containing Muriatic
  Acid.
  
• Large amounts of lithium batteries, especially, ones that have been stripped.
  
• Soft silver or gray metallic ribbon (in chunk form) stored in oil or Kerosene.
  
• Propane tanks with fittings that have turned blue.
  
• Occupants of residence going outside to smoke.
  
• Strong smell of urine, or unusual chemical smells like ether, ammonia or acetone.
