What Are Amphetamines?

Amphetamines are a classification of drugs that include illegal drugs sold on the streets as well as drugs that are prescribed to treat certain conditions.

Any amphetamine, regardless of its legal or medical status, is a central nervous system stimulant. When someone uses amphetamines, it speeds up most of the functions of the brain and body.

In terms of prescription use, amphetamine might be given to help treat the symptoms of attention deficit hyperactivity disorder (ADHD), or less commonly symptoms of narcolepsy or obesity.

  • Methamphetamine (this is also known as crystal meth)
  • Liquid methamphetamine

When someone uses amphetamines, it affects their central nervous system. These stimulants will speed up how messages move between the brain and body. Someone on amphetamines may feel more alert and more cognitively and physically active. When they’re used, it can also create a euphoric high because they release dopamine into the brain.

  • Increased heart rate
  • Increased blood pressure
  • Weight loss and decreased appetite
  • Insomnia and sleep disturbances
  • Digestive problems
  • Changes in mood and rapid mood swings
  • Paranoia
  • Anxiety
  • Panic attacks
  • Aggression
  • Hallucinations

The symptoms of methamphetamine abuse can be even more pronounced and severe. Methamphetamine, also referred to as meth or crystal meth, is a highly addictive and deadly drug. Signs of methamphetamine abuse can include skin sores, severe weight loss, and dental problems.

Signs and Symptoms of Amphetamine Addiction

Abusing amphetamine doesn’t necessarily mean someone is addicted. Addiction is a chronic disorder, and it can be diagnosed as is the case with other medical conditions. It is possible to become addicted to amphetamine with repeated exposure.

Essentially, when someone uses amphetamine and it triggers an unnatural release of dopamine into the brain, this creates a reward response. That reward response means that the continual use of the substance creating it is reinforced by the brain. In this case, it’s amphetamine.
