The laws governing the use and supply of drugs for medical purposes are not part of the Misuse of Drugs Act. A different set of categories apply, which are defined in the Misuse of Drugs Regulations. This sets out five schedules, each with their own restrictions. These restrictions say that a person can possess and use certain drugs if they have the proper prescriptions for them. A prescriptions must be given by somebody who is licensed to provide it (e.g., a medical doctor). The drug itself must be supplied by somebody who is licensed to supply it (e.g., a pharmacy).
