What is Meth?

Meth is a whitish or yellowish crystalline powder, crystals or pill. It can be snorted, smoked, injected, or swallowed. It is composed of pseudoephidrine, a decongestant, and a number of toxic ingredients such as dry cleaner or lye.

Common chemicals: acetone, lithium, toluene, hydrochloric acid, red phosphorus, sodium hydroxide, sulfuric acid

Meth can be prescribed by a doctor but its uses are limited and it is taken in much smaller doses than abusers.


Meth is a synthetic stimulant, which excites the central nervous system. It causes an increased alertness or physical activity, elevating mood and energy, and then leads to rebound depression and anxiety.
