What are the effects of speed?
Speed makes users feel very up, alert and energised, but can also make them agitated and aggressive.  It can also have other effects:

  • Speed makes people feel wide awake, excited and chatty. 
  • Clubbers take it because it gives them the energy to dance for hours without getting tired.
  • Amphetamines were once the main ingredient in diet pills because they stop people feeling hungry.
  • Speed use can lead to agitation, panics or even a psychotic episode (this is a mental state when you see or hear things which aren't there and have delusions).
