Drugs that affect the brain in a way that alters our emotions, behaviour or consciousness are said to be psychoactive.

There are three main categories of psychoactive drugs: stimulants, depressants and hallucinogens.

Some drugs can make you feel more energetic, while others decrease your emotions or make you see things that don't exist.

Drugs can be very dangerous: they can distort reality and often lead to harmful addiction.
