Infectious diseases have been treated in a variety of ways in the past and, as bacteria mutate, new medicines will be needed in the future.
Learn about these treatments, and also what happens to medicines, and drugs, when they are swallowed, injected or inhaled.
A drug is a substance which alters the way in which the body works. It can affect your mind, your body or both. In every society there are certain drugs which are used for medicine, and others which are used for pleasure. Usually some of the drugs which are used for pleasure are socially acceptable, while others are illegal.
