What is Amphetamine?

From Ephedra to amphetamine – A history of amphetamines

Amphetamines are derived from Ephedra, which is a bush native to central Asia and Mongolia, it also grows in the southwestern United States. The dried stems and leaves of the Ephedra plant can be dried and boiled in water to make a tea.

Amphetamine ingredients were first formed into a more complex substance or compound in 1887 in Germany by Romanian chemist Lazăr Edeleanu who named it phenylisopropylamine. A team of Japenese and Chinese scientists isolated ephedrine from Ephedra, and it was developed for production in the 1920s.

It was first introduced as an over-the-counter nasal inhaler in the United States as Benzedrine, to treat asthma and to raise low blood pressure. Later in the 1930s amphetamine preparations were also available to treat the sleeping disorder narcolepsy as well as to treat attention deficit hyperactivity. Dozens of amphetamine preparations were produced, and amphetamine weight loss pills were marketed. People quickly discovered that amphetamines increased energy, took away fatigue, hunger and the need for sleep.

The potency of amphetamines became widely appreciated during the Second World War. Pills were handed out along with food, cigarette rations, to improve endurance, delay sleep and perhaps to increase aggression. Soldiers in Allied, German and Japanese forces took amphetamines in enormous amounts. By the end of the war, many cases of psychosis among servicemen were reported. As the addictive properties of the drug became known, governments began to place strict controls on the sale of amphetamines. As a result of the United Nations 1971 Convention on Psychotropic Substances, amphetamine became a schedule II controlled substance, as defined in the treaty, in all 183 state parties. In the United Kingdom amphetamine is a class B drug that allows for its use as a medical treatment.

As a result, clandestine laboratories sprang up to meet demand. Illicit amphetamines are made and sold illegally. Their quality and purity are questionable – they can be a mix of drugs, binding agents, caffeine and sugar.

Other names for amphetamine  

  • Some examples of amphetamines include:
  • dexamphetamine, which is used for medical purposes to treat conditions such as Attention Deficit Hyperactivity Disorder (ADHD); and
  • amphetamine sulphate, known mainly as amphetamine speed
  • methamphetamine, which is a more potent form of amphetamine, known mainly as ‘crystal’, ‘meth’, ‘rock’ or ‘ice’.

Some amphetamine slang names

  • bennies
  • black beauties
  • blue boy
  • amphetamine paste (commonly known as ‘base)

The use of stimulant drugs such as amphetamines that are used as a medication, such as dexamphetamine, Adderal is usually produced as a small white pill. A doctor prescribing them will use them to treat conditions like Attention Deficit Hyperactivity Disorder (ADHD). Amphetamine-based medication in children appears to prevent unwanted changes in brain function and structure.

As a street drug, amphetamine is generally swallowed as a pill, smoked or snorted as a powder, or mixed with water and injected. Amphetamine has a bitter taste and may have an odour of rotten eggs. Powdered methamphetamine is white, yellow, pink or green, depending on its method of manufacture.

Several forms of amphetamines are notable for their abuse potential, including amphetamine sulfate or hydrochloride (speed), (crystal meth or ice), and so-called designer drugs, including 3,4-methylenedioxymethamphetamine (MDMA or ecstasy), 3,4-A methylenedioxyamphetamine (MDA or Adam), and 3,4-methylenedioxy-N-ethylamphetamine (MDEA or Eve).

What are the short-term side effects of amphetamine?

Amphetamine symptoms and effects vary from person to person, depending on your mood, your personality, where you are, who you are with, and how much you have taken.

The seemingly additional energy provided by amphetamines actually comes from using up the stores of neurotransmitters in the central nervous system. Rather than being released in short bursts as needed for the body “fight or flight” response, amphetamine effects cause an enormous amount to be released at once. This release is inevitable, followed by the feeling caused by depletion of these neurotransmitters – the sluggishness of withdrawal. An amphetamine dosage may increase attention and performance, but exhaustion eventually takes over, and performance deteriorates as the effects wear off. A person on amphetamines is often nervous, suspicious and hyperactive.

Speed may make you energised, but it can also make a person feel agitated and show signs of aggression, bringing on a rise in body temperature, heart rate blood pressure and can affect your breathing.

What are the long-term effects of taking amphetamines / methamphetamine?


With repeated use, tolerance to the drug develops and attempts to reduce the dose result in depression and lethargy. Eventually, users are caught between being overstimulated when using the drug and overly depressed if they have not taken enough. It is impossible to maintain a satisfactory balance. Frequent abuse of amphetamines can produce a psychosis that resembles amphetamine-induced schizophrenia. This amphetamine psychosis is characterised by paranoia, picking at the skin, preoccupation with one’s own thoughts and auditory and visual hallucinations. Violent and erratic behaviour is often seen among chronic abusers.

On the biological level, long term amphetamine drug use alters the sensitivity of the postsynaptic membrane receptors in the central nervous system, eventually leading to neurochemical exhaustion. If only low doses are taken, nerve receptors will subsequently regain their sensitivity when amphetamine use is stopped.

Another strong form of amphetamine is known as methamphetamine. High doses of methamphetamine cause permanent damage to the nerve endings of the serotonin and dopamine neurons. The effect of this may not be immediately apparent since there are billions of such nerves. However, as people get older and experience the normal ageing related loss of dopamine and serotonin neurons, this deficit can start to become noticeable in the form of movement disorders such as Parkinson’s disease or mood disorders such as depression.

Amphetamine withdrawal

A medical dose of amphetamines seldom exceeds 60 mg per day and is unlikely to cause withdrawal symptoms when it is stopped. In contrast, heavy amphetamine users develop a tolerance to the effects and may need a dose up to 100 times greater than the original one. Withdrawal causes a state of depression that may last for weeks resulting in a speed run/crash cycle. Amphetamine addiction withdrawal generally produces the opposite of the stimulating effects. These conditions produce the amphetamine comedown effects users experience.

Physically there can be muscular aches, and abdominal pain chills tremors and voracious hunger. Apathy long periods of sleep increased appetite fatigue, and a sense of sluggishness are common.
