+ Enzyme, Enzyme structure: Biochemistry :: Molecular biology
  * Some chemicals can help an enzyme do its job even better. These are called 'activators'. Sometimes, a chemical can slow down an enzyme or even make the enzyme not work at all. These are called 'inhibitors'. Most drugs are chemicals that either speed up or slow down some enzyme in the human body.
+ Illegal drugs, Health effects of drugs
  * Drugs can have many different effects on a person's health. However even if a drug doesn't cause any deaths directly, there are other health effects to be aware of. People who are intoxicated may do things they otherwise would not do, and they may be unable to safely drive or operate machinery.
  * Many drugs are used as medicine to help make sick people better. Nitrous oxide and ketamine are used as anaesthetics to put people and animals to sleep during a surgical operation. Amphetamines can even be legally prescribed by a doctor for attention disorders in some countries, such as the United States.
+ Medication
  * A' medication' means use of licenced drug. Such a drug is supposed to treat or cure an illness. Some drugs are freely sold. Other drugs are so powerful or dangerous that a doctor must give permission to use the drug. Some drugs are sold only when the purchaser shows a medical prescription to the seller of medicines.
+ Porphyria: Diseases
  * Porphyria' is the name for certain medical conditions or diseases. Those who suffer from the disease can not make certain substances in the blood. The condition may be because of a genetic deficiency or because it was acquired in some way. This will manifest in either skin problems, or some diseases of the nervous system, or both. Drugs are available that can at least treat the symptoms. This disease is most common in European countries and often affects the skin. When someone is affected by Porphyria they will start to lose their hair about two weeks after having an attack. There is no cure for the hair loss. However, there is medication available to help prevent attacks.
  * Drugs act differently in different amounts. It is therefore important to take the right amount. The amount of the drug taken is called a dose. Aspirin is often prescribed against fever, or as an analgesic. One of the side-effects of Aspirin is that it makes the blood thinner. For this reason, it can also be used to prevent strokes, or heart attacks - in a much lower dose than the one used to treat fever, though.
  * It is very important to keep taking the drug until the doctor says to stop because someone can feel better but still be sick. When a doctor says what drug to take, how much of it, and for how long, it is called a prescription. Drugs may cause addiction. Some drugs are illegal because they are very addictive. These drugs are really expensive, too.
