A drug is a medicine or other substance which has a physiological effect when ingested or otherwise introduced into the body. A drug of abuse is a drug taken for non-medicinal reasons (usually for mind-altering effects). Drugs of abuse can lead to physical and mental damage, dependence and addition.
