Drugs are medicines or addictive substances. Addictive substances are harmful and we should keep away from them. Medicines, however, can help us recover from illness but only if taken correctly. A doctor is qualified to prescribe drugs as medicine and must always be informed before taking a new medicine.

Some people are allergic to medicines (such as penicillin) and it's important to let health professionals know. There are drugs for almost every ailment ~ from a cold to hay fever to aches and pains ~ even to help you sleep at night.
