The drug ‘speed’ is another name for amphetamine. Amphetamine is either taken orally or injected, if injected it enters the bloodstream quicker than by ingesting it. Amphetamine is taken by clubbers or dancers because it gives the person taking it a burst of energy and they will feel wide awake. Amphetamines used to be used to suppress hunger and was often used in diet pills. ‘Speed’ is a Class B drug and people who use it often become dependent on the drug, they then have to up the amount they take to get the same effect. This then turns into an addiction.
