According to the U.S. Department of Justice, Methamphetamine is a powerful, highly addictive stimulant drug that dramatically affects the central nervous system. It is usually illegally produced and distributed.

Meth comes in several forms, including powder, crystal, rocks, and tablets. When it comes in the crystal form it is called “crystal meth.”

Methamphetamine is neurotoxic, meaning it damages the nervous system. Meth use can cause dependence and addiction psychosis, stroke, dangerously high body temperature, and cardiac arrhythmia. Withdrawal often results in severe depression and paranoia.

Meth can be taken by swallowing, snorting, smoking, or injecting it with a hypodermic needle.

HOW IS METH MADE?

Unlike drugs such as marijuana, cocaine, and heroin, which are derived from plants, meth can be manufactured using a variety of store bought chemicals.

The most common ingredient in meth is pseudoephedrine or ephedrine, commonly found in cold medicine. Through a cooking process the pseudoephedrine or ephedrine is chemically changed into meth. The ingredients that are used in the process of making meth can include: ether, paint thinner, Freon®, acetone, anhydrous ammonia, iodine crystals, red phosphorus, drain cleaner, battery acid, and lithium (taken from inside batteries).

Meth is often manufactured or "cooked" in very crude laboratories. Many of these labs are not sophisticated operations and do not require sophisticated chemistry equipment. And the people who cook the meth usually do not have any chemistry training. Cooking meth is relatively simple, but highly dangerous and toxic.
