1. Stimulants Stimulants are drugs that stimulate the Central Nervous System. These substances tend to increase alertness and physical activity. They include Amphetamines, Cocaine, Crack and some inhalants like Amyl or Butyl Nitrites. Caffeine (present in tea, coffee and many soft drinks) is also a mild stimulant drug.
2. Depressants These are substances that slow down or depress the Central Nervous System. Depressant drugs include alcohol, barbiturates and tranquillizers. Its worth remembering that, although alcohol is a legal drug and can be purchased by any person over 18 years old, it can be a dangerous drug, particularly when abused.
