Amphetamines are stimulants that speed up the body.

"The main action of amphetamines is to increase the synaptic activity of the dopamine and norepinephrine neurotransmitter systems. Amphetamines can:

  1. cause the release of dopamine from axon terminals.

  2. block dopamine reuptake.

  3. inhibit the storage of dopamine in vesicles.

  4. inhibit the destruction of dopamine by enzymes.

"All of these actions result in more dopamine in the synaptic cleft where it can act on receptors."
