The Negative Effects of a Meth Addiction on the Body

Having a meth addiction will have consequences both short-term and long-term. The brain and your body will be harmed in a way it may not recover.

Methamphetamine is an addictive stimulant that affects the central nervous system.

We will inform you of the short-term and long-term effects of having a meth addiction in this article.

Short-Term and Long-Term Effects of Meth Addiction

According to the National Institute on Drug Abuse (NIDA), meth increases dopamine in the brain, disrupting the reward system. To keep that same level of “high,” meth is abused.

NIDA lists the short-term effects of meth, which include:

  • increased wakefulness and physical activity
  • decreased appetite
  • faster breathing
  • rapid and/or irregular heartbeat
  • increased blood pressure and body temperature

Long-term effects as stated by NIDA include, but not limited to:

  • rapid weight loss
  • insomnia
  • reckless behavior
  • paranoia
  • anxiety
  • skin sores from scratching
  • memory loss and confusion
  • increased risk for Parkinson’s disease
  • deteriorating dental health, resulting in “meth mouth”
  • hallucinations

Infectious diseases can also be long-term, such as HIV, hepatitis B, and C because of needle sharing. This leads to reckless behavior that may lead to more infections. According to NIDA, “meth use may worsen the progression of HIV/AIDS and its consequences.” Nerves are then damage, leading to more cognitive and emotional issues, which involve learning, understanding, thinking, and remembering.

Also, it is possible to overdose on meth.


Having a meth addiction is not worth it both in the short-term and long-term.

There are ways to treat a meth addiction such as coping strategies, cognitive-behavioral therapy, or checking into substance abuse rehab.

NIDA says it is possible to recover from a meth addiction with access to effective treatments that address the medical and personal problems resulting from long-term use.

If you or someone you know is suffering from a meth addiction, seek professional help.
