Amphetamines usually come in the form of a white powder but can also be in anything from bright pink to dirty grey

The powder is usually sniffed but can also be smoked or injected.

Amphetamine is a stimulant, it produces feelings of energy and confidence, and relieves tiredness. There is little need for food or sleep. At higher doses there is strong sense of exhilaration. The effects of a single dose can last for several hours and another dose is often required to avoid the effects of the 'come down'

Feelings of anxiety, irritability, restlessness and paranoia are common. Frequent high doses can lead to a collection of symptoms including delirium, panic attacks, psychosis and hallucinations. Long term use can lead to depression, constant tiredness, delusions, hallucinations and paranoia. The body's ability to fight disease is lowered often leading to infections. Suicide has been known in cases of sudden withdrawal

As with most stimulants dependence is psychological. Tolerance develops easily, leading to the need for greater doses to produce the same effect.

Amphetamines are prescription only drugs and come under the Medicines Act. Patients can only possess them if they have been prescribed for them by a doctor. They are also subject to the Misuse of Drugs Act and most are in class B, unless prepared for injection when they become class A. It is an offence to possess (unless prescribed), produce or supply them and also to let premises be used for their production or supply.
