Signs & Symptoms of Meth Addiction

The signs, symptoms, and effects of meth addiction can be different for every person impacted. Learning about meth addiction is one of the first steps towards getting better.

Understanding Meth

Learn about meth and substance abuse

Methamphetamine, or meth, is an illicit stimulant drug. Popular for a variety of reasons, including because it is relatively easy to synthesize, meth use brings powerful feelings of pleasure and invincibility. This euphoric “rush” can be so potent that meth users often abuse the drug again and again in pursuit of a high, which may lead them to develop a methamphetamine use disorder. A meth use disorder can be debilitating, and often a person will require the help of a team of substance abuse professionals at a comprehensive substance use treatment center in order to successfully overcome his or her addiction.


Meth addiction statistics

Although meth use seems to be decreasing throughout the United States, the 2012 National Survey on Drug Use and Health (NSDUH) found that 1.2 million Americans had used meth within the previous year, and 440,000 had used the drug within the previous month. Data from the Drug Abuse Warning Network (DAWN) found that meth was responsible for 103,000 emergency room visits in 2011, and the Treatment Episode Data Set (TEDS) reported that 5.6 percent of substance use treatment center admissions were related to meth.

Causes and Risk Factors

Causes and risk factors for meth addiction

As with other substance use disorders, one’s risk of developing a meth use disorder is affected by a number of factors, which may include the following:

Genetic: Genetics can have a strong influence on the development of methamphetamine use disorder. For example, individuals who have a genetic predisposition to impulsivity or novelty-seeking may be at increased risk for developing a problem with meth.

Environmental: Exposure to meth before birth can increase a person’s risk of developing a meth use disorder. In addition, growing up in a family where parents or siblings use meth, being exposed to community violence, living in an unstable home environment, having a mental illness, and being around meth dealers and users all increase the chance that a person will develop a meth use disorder.

Risk Factors:

  • Certain personality characteristics, such as impulsivity or desire for novelty
  • Presence of other mental health disorders
  • Being exposed to meth in the womb
  • Growing up in an instable household
  • Being around others who use meth
  • Exposure to violence in one’s community
  • Having parents who use meth
