In Florida, there are laws that prohibit the sale, manufacture, use and distribution hundreds of drugs. These controlled substances are classified as Schedule I through Schedule IV drugs.
Schedule I drugs, for example, have no accepted medical use and are likely to be abused. Schedule II dugs are habit-forming but can be used in some medical situations, with significant restrictions. Schedule III substances are accepted as a form of medical treatment and are less addictive. Schedule IV drugs have a low risk for abuse.
