Substances: Stimulants

Stimulants are substances that act directly on the central nervous system to speed up parts of the brain and body. Adrenaline is an example of a naturally occurring stimulant in the body.

Some athletes may use stimulants in an attempt to increase alertness, reduce tiredness, and increase their competitiveness and aggressiveness.

Examples of stimulants are amphetamines, cocaine, ephedrine, and mesocarb.

Side effects

Stimulants can cause problems with heat regulation, faster breathing, problems with coordination and balance, aggressive behaviour, dehydration, weight loss and hand tremors.

Other side effects may include increased heart rate, palpitations and irregularities, insomnia, increased blood pressure and sweating.

Dependence and addiction are risks associated with abuse of stimulants.
