Drug is a chemical substance used in the treatment, cure, or prevention of disease or used to enhance physical or mental well-being. Drugs may be prescribed for a limited duration, or on a regular basis for chronic disorders. Prescription drugs, as opposed to over-the-counter drugs, are regulated medications that must be authorized for sale or distribution by licensed physicians, nurse practitioners, paramedics, dentists, optometrists, and veterinarians.
