Stimulants are a class of drugs that speed up messages travelling between the brain and body. They can make a person feel more awake, alert, confident or energetic.1
Stimulants include caffeine, nicotine, amphetamines and cocaine. Large doses can cause over-stimulation, resulting in anxiety, panic, seizures, headaches, stomach cramps, aggression and paranoia. Long-term use of strong stimulants can have adverse effects.
