Different kinds of Drugs

Drugs are categorised by their affects. The categories are; Stimulants, Depressants, Hallucinogens and Analgesics.

  • Stimulants - have an affect on your central nervous system. This increases your brain activity, making you excited and energetic. Stimulant drugs include amphetamines and cocaine.
  • Depressants - depressant drugs have the opposite affect on your central nervous system, slowing down your brain activity. You may become lethargic. Alcohol and solvents are both depressants.
  • Hallucinogenics - are drugs that distort the things you see and hear giving you the impression that things are there when they are not. LSD, magic mushrooms and cannabis are hallucinogens.
  • Analgesics - are painkilling drugs. Aspirin and paracetamol are both analgesics, as is heroin.

NB: Some drugs such as Ecstasy can appear in different categories. The pharmacology (what the drug consists of) can vary so the list above is only a guide. For detailed information and advice speak to your local Drug Advice Centre or call the National Drugs Helpline.
