Controlled Substance

A Controlled Substance is any drug or substance the use or possession of which is controlled by state or federal controlled substance statutes. Controlled substances are listed on five schedules and these schedules are subjected to different types of regulation. Controlled substance laws make it legal for physicians to prescribe many of the drugs on the controlled substance schedules; however, possession or sale of those same drugs would be illegal if sold on the street.
