What Is Crystal Meth?

Street Names for Crystal Meth

Crystal meth is known by many slang terms including:

  • Glass.
  • Blade.
  • Crystal.
  • Quartz.
  • Ice.

Crystal methamphetamine (crystal meth) is a powerful central nervous stimulant with highly addictive properties.

Crystal meth is the illicit, crystalline form of methamphetamine. Legally manufactured methamphetamine is classified as a Schedule II drug by the United States Controlled Substances Act, meaning:

  • It has a high potential for abuse.
  • It has a currently accepted medical use.
  • Abuse of it may lead to severe psychological or physical dependence.

Pharmaceutical methamphetamine is used in medications that treat Attention Deficit Hyperactivity Disorder (ADHD) and, infrequently, in cases of severe obesity.

The crystal form of methamphetamine – the street drug crystal meth – has no medical applications, and is exclusively abused as a recreational substance.

Effects of Crystal Meth Abuse

The effects of crystal meth in recreational doses are powerful, and can lead to psychological and physical addiction.

Crystal meth works by affecting the communication chemicals dopamine, norepinephrine, and serotonin in the brain and activating the cardiovascular and central nervous systems.

The effects of crystal meth in recreational doses are powerful and can lead to psychological and physical addiction. The Canadian Centre on Substance Abuse reports that users initially report feeling confident and powerful, with limitless energy, increased productivity, enhanced sexual performance, and decreased appetite.

Once these initial euphoric effects wear off, however, the experience can take a bad turn–with chronic abuse leading to serious and immediate negative consequences:

  • Anxiety.
  • Depression.
  • Mental confusion, psychosis, and paranoia.
  • Fatigue.
  • Headaches.
  • Extreme weight loss.
  • Picking at your skin, resulting in scabs.
  • Tooth decay—or, “meth mouth”.

  • Sensation of insects crawling on/under your skin.
  • Jaw clenching.
  • Seizures.
  • Respiratory disease.
  • Heart disease.
  • Cardiac arrest.
  • Stroke.
  • Death.

Other potential long-term health effects of crystal meth abuse include:

  • Microvascular hemorrhage.
  • Eye damage.
  • Vision impairment.
  • Markedly disrupted sleep patterns.

Statistics on Crystal Meth Use


  • Per the 2015 National Survey on Drug Use and Health (NSDUH), more than 1.7 million people age 12 or older reported illicit methamphetamine use in 2015, and nearly 900,000 people age 12 or older reported use in the past month.
  • According to the Drug Abuse Warning Network (DAWN) Report, meth was involved in almost 13% of all illicit substance emergency department visits in 2011.
  • The NSDUH also found more than twice as many men used illicit methamphetamine than women in 2015.
  • Per the Monitoring the Future Study, use rates of meth among 8th, 10th, and 12th graders showed a steady decline between 2012 and 2015—a positive trend which will hopefully continue in coming years.

Crystal Meth Abuse Treatment

Treatment for methamphetamine abuse may take on multiple forms, depending on the individual’s needs. The first phase of treatment, detoxification, may proceed more smoothly with careful monitoring by an experienced medical staff. Withdrawal can be profoundly uncomfortable, and can sometimes elicit depressive episodes—relapse risks are high during the period of acute detox.

Don’t wait to reclaim your life. Learn about treatment programs.

Acute symptoms of abuse are often treated with medications to alleviate the discomfort of side effects and withdrawal:

  • Hyperactivity, agitation or psychotic features—If needed, may be treated with a dopamine-blocking medication, such as haloperidol–an antipsychotic that decreases abnormal excitement in the brain.
  • Other behavioral and psychiatric effects—Benzodiazepine drugs such as diazepam (Valium) may be used to relieve anxiety, muscle spasms, and seizures.

Dependence and addiction can often prove difficult to manage, due to high rates of dropout and relapse, severe craving, protracted mental health issues (including depression and psychosis), and the inability of some users to experience pleasure in the absence of the drug.

Currently, there is no widely accepted model for crystal meth abuse treatment. In the past, antidepressants were utilized, but this treatment was not found to be especially effective in the long run.

Modern treatment programs use various forms of counseling or therapy to address the issues surrounding abuse and dependence. Therapies that have been found to be effective are:

  • Contingency Management—Uses positive reinforcement to keep patients abstinent, leading to longer periods of drug abstinence.
  • Cognitive Behavioral Therapy—Examines the role of substance abuse in a patient’s life and develops skills to avoid relapse; includes the Matrix Model approach.
  • The Matrix Model—Incorporates cognitive-behavioral therapy, addiction education, relapse prevention education, 12-step or self-help programs, and weekly urine tests to assure abstinence. This method has been found to be very effective during treatment.

Teen Crystal Meth Abuse

Adolescents are at particular risk for the dangers of crystal meth abuse. Human brains continue to develop until the mid-20s, and powerful drugs such as crystal meth can have a major impact on brain development.

Teens may also be unaware of the risks. In fact, though many youth users acknowledge the health risks and social costs of heavy use, they still associate the use of the drug more positively than heroin or crack cocaine.

Drug education regarding the dangers that come with abuse is a vital part of abuse prevention. Talking with your teen about the risks associated with use can help prevent young abuse.
