Drug

A drug is a natural or chemical substance that is used for medicinal or recreational purposes. A drug can be used to relieve pain when a person has sustained an injury or is going through a surgical procedure. However, a drug can also enhance one's own abilities and provide stimulative energy for completion of a task. An unfortunate problem with a drug, however, is that it can be addictive, requiring the person to take in more of the drug to maintain their stability.
