Methamphetamine is a highly addictive drug, whether injected, snorted or smoked, that affects the brain and central nervous system. Methamphetamine increase levels of the neurotransmitter dopamine, which stimulates brain cells, enhancing mood and body movement.

 

Short-Term Effects

When methamphetamine is injected or smoked it immediately produces an intensely pleasurable sensation known as a "rush" or a "flash" by releasing high levels of dopamine in the brain. Snorting methamphetamine produces an euphoric sensation, but not a rush.

Even taken in small amounts, methamphetamine can cause:

  • Increased wakefulness.
  • Increased physical activity.
  • Decreased appetite.
  • Increased respiration.
  • Hyperthermia.
  • Increased heart rate and blood pressure.
  • Irregular heartbeat.
  • Cardiovascular collapse.

Other effects of meth use on the central nervous system can produce the following symptoms:

  • Irritability.
  • Prolonged insomnia.
  • Confusion.
  • Anxiety.
  • Tremors.
  • Convulsions.
  • Paranoia.
  • Aggressiveness.

Hyperthermia and convulsions can be fatal. Methamphetamine can also cause irreversible damage to the blood vessels in the brain, resulting in a stroke.

 

Long-Term Effects

Long-term methamphetamine abuse results in many damaging effects, including addiction. Addiction is a chronic, relapsing disease, characterized by compulsive drug-seeking and drug use which is accompanied by functional and molecular changes in the brain.

In addition to being addicted to methamphetamine, chronic methamphetamine abusers exhibit symptoms that can include violent behaviour, anxiety, confusion, and insomnia. They also can display a number of psychotic features, including paranoia, auditory hallucinations, mood disturbances, and delusions (for example, the sensation of insects creeping on the skin, which is called "formication"). The paranoia can result in homicidal as well as suicidal thoughts.

With chronic use, tolerance for methamphetamine can develop. In an effort to intensify the desired effects, users may take higher doses of the drug, take it more frequently, or change their method of drug intake. In some cases, abusers forego food and sleep while indulging in a form of binging known as a "run," injecting as much as a gram of the drug every 2 to 3 hours over several days until the user runs out of the drug or is too disorganized to continue.

Chronic abuse can lead to psychotic behaviour, characterized by intense paranoia, visual and auditory hallucinations, and out-of-control rages that can be coupled with extremely violent behaviour.
