§ Mr. Gordon Prentice
To ask the Secretary of State for the Home Department what considerations led him to reschedule dronabinol under the Misuse of Drugs Act 1971 to allow it to be used medicinally. 
§ Mr. Sackville
The amendment to permit the medical use of dronabinol reflected its rescheduling under the United Nations convention on psychotropic substances.
The rescheduling under the United Nations conventions was based on advice from the World Health Organisation that dronabinol had been demonstrated to have a specific medical use as an anti-nausea drug for patients undergoing chemotherapy treatment for cancer.
