§ Mr. McMaster
To ask the Secretary of State for the Home Department what are the legislative differences relating to drugs which are classified as schedule 3 as compared with those classified as schedule 4; and if he will make a statement. 
§ Mr. Michael Forsyth
The differences between the controls on drugs in schedule 3 and schedule 4 of the Misuse of Drugs Regulations 1985 are as follows:
- possession of schedule 3 drugs requires authority. Possession of schedule 4 drugs does not require authority when they are in the form of medicinal products;
- import and export licences are required for schedule 3 drugs but not for schedule 4 drugs;
- certain schedule 3 drugs are subject to the Misuse of Drugs (Safe Custody) Regulations 1973 which require them to be kept in a locked cabinet or locked receptacle. The remaining schedule 3 and all schedule 4 drugs are exempted from these requirements;
- schedule 3 drugs are subject to specific requisitioning requirements; prescriptions must be handwritten by doctors; supply on prescription is subject to certain requirements; and there are labelling requirements for some containers. Schedule 4 drugs are exempted from these requirements.
