A drug is a chemical that can change the way your mind and body work. If you are not very well, a doctor might prescribe a medical drug (medicine) to help you get better. These medicines should only be taken by the person who they are meant for.

There are other drugs that are easier to get hold of. For example, cigarettes contain a drug called nicotine, alcohol is also a drug and the caffeine found in tea, chocolate and coffee is a drug, too.

ALL OF THESE SUBSTANCES WILL AFFECT YOU IN SOME WAY.
