About Methamphetamine

Hear from others dealing with the effects of crystal meth addiction.

Methamphetamine is a highly addictive stimulant that can have long-lasting effects on your body. This is a man-made substance that, with the advent of other more efficacious prescription stimulants, now has limited therapeutic use and is only very rarely indicated for intractable ADHD and severe obesity.

Crystal meth is methamphetamine in the form of a rock-like crystal that is usually a semitransparent white or blue color. This substance is always illegal and has no other purpose than for abuse.

Crystal meth is mostly heated and then smoked in a glass pipe. Less frequently, the drug is crushed up to be snorted or injected. Smoking crystal meth speeds the delivery of the substance into the bloodstream, which further promotes the addictive nature of the substance.

Abuse of crystal meth is prevalent in the United States, with the National Institute on Drug Abuse reporting that in 2009, 1.2 million American adults and children 12 years old and over had abused the drug at least once in the previous year. The Drug Enforcement Administration claims that nearly 12 million people in the US reported lifetime use of crystal meth or methamphetamine for non-medical reasons in 2011.

Crystal meth and methamphetamine abuse is a global problem with close to 25 million abusers.

Short-Term Effects of Crystal Meth

Consistent use of crystal meth can result in severe anxiety, paranoid and insomnia. Additionally, thoughts of suicide – or even homicide – have been noted in some meth abusers.

People that use crystal meth are looking for the immediate and long-lasting high for which the drug has gained notoriety. When the substance is smoked, the vapor moves quickly from the lungs to the bloodstream—where it then travels rapidly to the brain. Since the drug acts as a stimulant throughout the brain and body, there is an almost instant euphoria, followed by an increase in energy and alertness—effects that can last for up to 12 hours.

Other desired effects of crystal meth include:

  • An intense, initial "rush" that may persist for 30 minutes.
  • Higher motivation to accomplish goals.
  • Confidence/feelings of improved intellect and ability to solve problems.

Unsurprisingly, the desirable effects of crystal meth quickly give way to the undesirable effects of the substance. For example, even short-term use of crystal meth can elicit erratic and even violent behavior when taken in large doses.

Side Effects

Other side effects of crystal meth include:

  • Loss of appetite.
  • Significant weight loss.
  • Change in sleeping patterns.
  • Severe mood swings.
  • Unpredictable behavior.
  • Tremors or convulsions.
  • Hyperthermia.
  • Elevated blood pressure.
  • Rapid heart rate.
  • Irregular heart rhythm.

Consistent use of crystal meth can result in severe anxiety, paranoid and insomnia. Additionally, thoughts of suicide – or even homicide – have been noted in some meth abusers.

What Is Tweaking?

When the crystal meth no longer yields a high, the user enters a stage sometimes referred to as “tweaking.” During this time, they may feel intense cravings and despair. It is at this point where psychotic symptoms present—with users sometimes struggling with delusions and other altered perceptions of reality. Experiencing this unsettling development signals a point in time where many will seek and enter treatment programs. With the presenting symptoms, they may begin sobriety in an inpatient mental health facility before being transferred to detoxification or rehabilitation services.

After the long-term insomnia and loss of appetite that active users experience ends, most people tend to do little more than sleep during the days after “tweaking.” After this crash, comes a period where the person dependent on crystal meth will be hungry, thirsty, and fatigued due to the effects of the substance. This period can last up to 2 weeks, and is sometimes accompanied by the onset of a clinically significant depression.

Some people take crystal meth to experience a specific set of stimulant side effects. This includes the decrease in appetite, increased energy levels, and increased metabolism that some users attempt to take advantage of to achieve weight-loss. Crystal meth also tends to increase libido, leading to abuse of the drug for that purpose alone.

It's safe to say that none of the perceived short term benefits of a dangerous drug like methamphetamine are worth the risk of developing a deadly dependency that come with them.

Long-Term Effects of Crystal Meth

Taken over a long period of time, crystal meth can cause severe physical and psychological issues as the short-term effects grow in intensity and complexity. Signs of long-term abuse include:

  • More persistent psychotic symptoms—including delusions, paranoia, and hallucinations.
  • Increased mental health issues like depression, anxiety and social isolation.
  • Confusion and odd behavior.
  • Feeling of bugs crawling on the skin.
  • Body sores from users picking at their skin.
  • Breathing problems associated with smoke inhalation.
  • Irreversible damage to blood vessels throughout the body, including the heart and brain.
  • Stroke.
  • Coma.

Severe crystal meth abuse can also cause outward signs of aging in users. Since the drug destroys tissues and blood vessels and hampers the body's ability to heal, users often develop acne, and the skin takes on a dull look and loses its elasticity. The teeth can begin to decay and crack, resulting in a condition known as “meth mouth.”

One of the most serious long-term side outcomes of crystal meth, however, is sudden death from cardiac arrest or stroke.

Pregnancy and Crystal Meth Abuse

The side effects of crystal meth can be swift and severe, especially for pregnant women. Crystal meth can cause a baby to be born prematurely and suffer birth defects—including cleft palate or heart abnormalities. Babies born to crystal meth users are often very small in size due to lack of nutrition and prenatal care during pregnancy. Crystal meth is also present in the breast milk of users, putting nursing babies at risk.

Crystal Meth Effects Quiz question 5

Crystal Meth Dependency


Crystal meth signals the brain to fire off an increased amount of dopamine, a chemical that causes a feeling of reward or pleasure.

The increased activity of dopamine is what scientists believe plays a large role in the development of addiction to certain drugs. It is thought that the positive feeling from dopamine is so strong – and intensely rewarding – that it reinforces the behavior initiated its release.

As users become more tolerant of crystal meth, they will need more of the substance to achieve the desired high and will take ever-increasing amounts, placing themselves at risk for overdose and furthering fueling the body’s dependency on the drug.

Over time – after a period of persistent stimulant intoxication – dopamine receptor activity is severely impaired, which can cause perceptions of decreased happiness and pleasure and even lead to permanent cognitive impairments.

Crystal Meth Withdrawal Treatment

Symptoms of withdrawal from crystal meth can include:

  • Feelings of depression.
  • Intense drug craving.
  • Anxiety.
  • Loss of energy.
  • Itchy eyes.
  • Sleep difficulties, ranging from oversleeping to severe insomnia.
  • Increased appetite.

Withdrawal from crystal meth can be very uncomfortable and may lead users to relapse in an attempt to alleviate the symptoms. Being in a medically supervised detox program can ensure management of symptoms and may help prevent relapse.

Successful completion of a detoxification period often marks the initial part of treatment, that later leads in to a more protracted stay at an inpatient rehab program or participation in a structured outpatient program.

Inpatient programs or residential rehabilitation can be highly effective methods for treating crystal meth addiction, in that they allow the user to focus intensely on sobriety with minimal distractions or temptations. Most programs range from 30-90 days, with longer stays available for more severe cases of addiction.

Outpatient or intensive outpatient drug treatment are additional valuable options to address the mental, behavioral and medical issues associated with crystal meth abuse.
