Some people ask, "What is meth?" or "What is crystal meth?" People often don't realize that meth and crystal meth are street names for methamphetamine. So the real question is, "What is methamphetamine?"
Methamphetamine is a highly-addictive, synthesized drug in the groups:
- Psychostimulant - also known as a stimulant; a drug that acts on the central nervous system, particularly the brain
- Amphetamine - a chemical class, including stimulants, based on a similar chemical core
In 1919, a Japanese pharmacologist first synthesized methamphetamine. In the 1930s, more chemical details were attained and inhalable methamphetamine was introduced. The euphoric and energizing effects were quickly seen leading to the drug's abuse. Methamphetamine was used during World War II and Operation Desert Storm troops and in spite of strict regulation and attempts to reduce illegal production, meth's illicit use still continues to grow.1

What is Meth? - How is Meth Used?
Methamphetamine can in used in the following ways:
- Ingestion (oral) - does not produce a rush due to digestion. Not a method used by meth addicts.
- Injection - intravenous use, also known as slamming, mainlining or shooting up, is the fastest way of getting methamphetamine into the bloodstream and brain, producing the high in the shortest amount of time.
- Smoking - involves heating and vaporizing meth and then inhaling the smoke.
- Snorting - similar to snorting with cocaine.
- Suppository - a less common method of use.
The faster methamphetamine enters the bloodstream the more likely it is to addict the user. Intravenous use is considered to be the most additive way followed by smoking, suppository, snorting and finally, eating.
