Substance abuse , also known as drug abuse , is use of a drug in amounts or by methods which are harmful to the individual or others. It is a form of substance-related disorder.

A drug is any substance that causes a change in an organism's physiology or psychology when consumed. Consumption of drugs can be via inhalation , injection , smoking , ingestion , absorption via a patch on the skin, suppository , or dissolution under the tongue. In pharmacology , a drug is a chemical substance, typically of known structure, which, when administered to a living organism, produces a biological effect. Pharmaceutical drugs are often classified into drug classes —groups of related drugs that have similar chemical structures , the same mechanism of action binding to the same biological target , a related mode of action , and that are used to treat the same disease. Another major classification system is the Biopharmaceutics Classification System.

Physicians have long recognized that different types of drugs affect people differently. Nonetheless, drugs may be categorized or classified according to certain shared symptomatologies or effects. The DRE categorization process is premised on these long-standing, medically accepted facts. DREs classify drugs in one of seven categories: central nervous system CNS depressants, CNS stimulants, hallucinogens, dissociative anesthetics, narcotic analgesics, inhalants, and cannabis. Drugs from each of these categories can affect a person's central nervous system and impair a person's normal faculties, including a person's ability to safely operate a motor vehicle.
