Crystal methamphetamine, commonly referred to as meth, is a man-made stimulant that is at the forefront of a dangerous drug epidemic in the United States. In addition to the harmful and addictive properties of meth, it can be inexpensively and easily made with harsh chemicals like battery acid, paint thinner or refrigerant. The toxins in meth are then secreted throughout the body which exacerbates the damage done to the brain, skin, internal organs and immune system.

What does meth do to the body?

Meth affects the central nervous system by flooding the brain with dopamine, the neurotransmitter responsible for feelings of pleasure and reward. Because meth provides the brain with an artificial source of dopamine, it can cause the neurotransmitter to fire abnormally. The brain will then chase that rush of dopamine, quickly facilitating addiction to meth. It may then be difficult for the brain to produce dopamine normally without the presence of meth.

Abuse of meth can be harmful to the body in a very short amount of time. It is a powerful stimulant that provides a rapid, intense and quickly addictive high. Due to the high being so short, individuals addicted to meth may use the drug continually in order to avoid coming down.

Meth short-term effects can include:


  • Irritability, erraticism and depression following the comedown from meth
  • Hallucinations
