What are amphetamines?

Amphetamines belong to a group of drugs called ‘psychostimulants’ (also commonly known as ‘speed) that stimulate the central nervous system. Amphetamines speed up the messages going to and from the brain to the body.

Most amphetamines are produced in backyard laboratories and sold illegally. People who buy amphetamines illegally are often buying these drugs mixed with other substances that can have unpleasant or harmful effects.
