SIGNS OF MANUFACTURING

At a site where methamphetamine is being manufactured, one would likely notice signs of use and dealing, in addition to smelling strong odors (often described as smelling like cat urine) observing large amounts of trash, canisters of denatured alcohol, camping fuel, muratic acid, and/or lye, multiple packages of over-the-counter medications containing pseudoephedrine (most often cold/allergy tablets or diet aids), coffee filters stained red (from red phosphorous used to accelerate the manufacturing process), rock salt, plastic tubing and glass jars, flasks, or cookware.

Most of these items have legitimate household uses, but the typical consumer will not possess ten cans of camping fuel or 20 packages of cold medication.
