Amphetamine Definition

Addiction is defined as a chronic, relapsing disease, characterized by compulsive drug-seeking and drug use and by neurochemical and molecular changes in the brain. Amphetamines are substances taken to boost energy, mood and confidence, as well as to suppress appetite (Amphetamine is a collective term given to amphetamines, dextroamphetamines and methamphetamines, all of which act similarly in the body. Out of these, methamphetamines are the strongest. (In the 1930s, they were used in nasal decongestants and to treat narcolepsy, ADHD and minimal brain dysfunction.) If you suspect someone of using this substance you can get a definitive answer by using a simple, private urine drug testing kit. There are easy-to-use amphetamine urine drug testing products at HDTK.com.

Health Hazards

Methamphetamine is a powerfully addictive stimulant that dramatically affects the central nervous system. The drug is made easily in clandestine laboratories with relatively inexpensive over-the-counter ingredients. These factors combine to make methamphetamine a drug with high potential for widespread abuse.

Methamphetamine is commonly known as "speed," "meth" and "chalk." In its smoked form, it is often referred to as "ice," "crystal," "crank" and "glass." It is a white, odorless, bitter-tasting crystalline powder that easily dissolves in water or alcohol. It was developed early in this century from its parent drug, amphetamine, and was used originally in nasal decongestants and bronchial inhalers. Methamphetamine's chemical structure is similar to that of amphetamine, but it has more pronounced effects on the central nervous system. Like amphetamine, it causes increased activity, decreased appetite and a general sense of well-being. The effects of methamphetamine can last six-to-eight hours. After the initial rush, there is typically a state of high agitation that in some individuals can lead to violent behavior.

Methamphetamine is classified as a psychostimulant, as are other drugs of abuse such as amphetamine and cocaine. We know that methamphetamine is structurally similar to amphetamine and the neurotransmitter dopamine, but it is quite different from cocaine. Although these stimulants have similar behavioral and physiological effects, there are some major differences in the basic mechanisms of how they work at the level of the nerve cell. However, the bottom line is that methamphetamine, like cocaine, results in an accumulation of the neurotransmitter dopamine, and this excessive dopamine concentration appears to produce the stimulation and feelings of euphoria experienced by the user. In contrast to cocaine, which is quickly removed and almost completely metabolized in the body, methamphetamine has a much longer duration of action and a larger percentage of the drug remains unchanged in the body. This results in methamphetamine being present in the brain longer, which ultimately leads to prolonged stimulant effects. It is very important to get the use of this drug stopped. One of the ways to do that is to do regular urine drug testing of the person who is using this drug. Urine drug testing products are available for purchase at HDTK.com

Methamphetamine comes in many forms and can be smoked, snorted, orally ingested or injected. The drug alters moods in different ways, depending on how it is taken. People often ingest amphetamines by snorting them through the nostril initially. However, the level of absorption through this form of intake is not as predictable and rapid as injection or smoking).

Immediately after smoking the drug or injecting it, the user experiences an intense rush or flash that lasts only a few minutes and is described as extremely pleasurable. Snorting or oral ingestion produces euphoria, a high but not an intense rush. Snorting produces effects within three-to-five minutes, and oral ingestion produces effects within 15-to-20 minutes.

As with similar stimulants, methamphetamine most often is used in a "binge and crash" pattern. Because tolerance for methamphetamine occurs within minutes -- meaning that the pleasurable effects disappear even before the drug concentration in the blood falls significantly -- users try to maintain the high by bingeing on the drug. In the 1980s, "ice," a smokable form of methamphetamine, came into use. Ice is a large, usually clear crystal of high purity that is smoked in a glass pipe like crack cocaine. The smoke is odorless, leaves a residue that can be re-smoked and produces effects that may continue for 12 hours or more.

Using amphetamines once is sufficient to induce some of these symptoms:

Short-Term Effects:

  • Enhanced mood and body movement
  • Increased wakefulness, physical activity
  • Increased respiration
  • Euphoria
  • Insomnia
  • Increased heart rate
  • Increased blood pressure
  • Reduced appetite
  • Cardiovascular collapse, death
  • Dilated pupils

Long-Term Effects:

  • Damage to brain cells containing serotonin
  • Over time, reduced level of dopamine resulting in Parkinson's-like symptoms
  • Weight loss
  • Confusion
  • Tremors
  • Convulsion
  • Paranoia
  • Hallucinations
  • Damage to nerve cells, causing strokes
  • Cardiovascular collapse, death

Effects from Withdrawal:

  • Irritability
  • Anxiety
  • Paranoia
  • Aggressiveness
  • Fatigue and long periods of sleep
  • Depression

Behaviors resulting from amphetamine intoxication such as withdrawal from others, experiencing hallucinations, paranoia, delirium perhaps occurring with violence and stereotyped behaviors such as repeatedly assembling and dissembling electronic equipment may resemble symptoms of schizophrenia. Personal and private amphetamine drug testing is an important part of helping an addict stop their substance abuse. Please visit HDTK.com to purchase your urine drug tests today.


  • According to the National Institute on Drug Abuse Web site, a study in Seattle showed that methamphetamine use was widespread in the homosexual and bisexual community and they reported using the drug when engaging in unsafe sex and unsafe needle-use, leaving them at risk for contracting and transmitting HIV and AIDS.
  • Meth can be injected with a needle, increasing the chance of contracting HIV/AIDS, hepatitis and other infectious diseases.
  • Often pure amphetamines are mixed with other substances such as sugar, glucose, bi-carb soda and ephedrine that can be poisonous, causing collapsed veins, tetanus, abscesses and damage to the heart, lungs, liver and brain.
  • Incessant use might result in addictions to other drugs such as benzodiazepines (a kind of anti-anxiety agent) taken to calm down so the individual can sleep.


While this class of drugs was initially unregulated, today legal uses are limited to prescription to treat attentional disorders, obesity, narcolepsy and depressive disorders. Causes of amphetamine addiction are largely related to features of the drugs. While the effects are almost immediate, tolerance is built up quickly, thus increasing the amount needed to produce the desired effect. During periods of nonuse, the user will recall the feeling of euphoria produced by the drug and desire to intake it again. According to the DEA, abuse of amphetamines began when they were used as a cure-all to keep people awake, train longer, treat depression and for weight control. According to the National Institute on Drug Abuse, a 2003 study revealed that 6.2 percent of high school seniors reported using methamphetamines at some point in their life, along with 5.3 percent of tenth graders and 3.9 percent of eighth graders. Among high school seniors, 3.2 percent reported methamphetamine use in the past year.


At this time the most effective treatments for methamphetamine addiction are cognitive behavioral interventions. These approaches are designed to help modify the patient's thinking, expectancies and behaviors and to increase skills in coping with various life stressors. Methamphetamine recovery support groups also appear to be effective adjuncts to behavioral interventions that can lead to long-term drug-free recovery.

There are currently no particular pharmacological treatments for dependence on amphetamine or amphetamine-like drugs such as methamphetamine. The current pharmacological approach is borrowed from experience with treatment of cocaine dependence. Unfortunately, this approach has not met with much success since no single agent has proven efficacious in controlled clinical studies. Antidepressant medications are helpful in combating the depressive symptoms frequently seen in methamphetamine users who recently have become abstinent.

There are some established protocols that emergency room physicians use to treat individuals who have had a methamphetamine overdose. Because hyperthermia and convulsions are common and often fatal complications of such overdoses, emergency room treatment focuses on the immediate physical symptoms. Overdose patients are cooled off in ice baths, and anticonvulsant drugs may be administered also.

Acute methamphetamine intoxication can often be handled by observation in a safe, quiet environment. In cases of extreme excitement or panic, treatment with anti-anxiety agents such as benzodiazepines has been helpful, and in cases of methamphetamine-induced psychoses, short-term use of neuroleptics has proven successful.)
