These Regulations amend the Misuse of Drugs (Supply to Addicts) Regulations 1997 (the “1997Regulations”) to the effect that, on the coming into force of section 19(2) of the Scotland Act 2012 which amends section 10 of the Misuse of Drugs Act 1971, the relevant licensing authority for the purposes of any licence issued under the 1997 Regulations is the Scottish Ministers where the licence specifies an address in Scotland, and the Secretary of State where the licence specifies an address in England and Wales. Regulation 3(b) inserts new paragraph(1A) into regulation 3 of the 1997 Regulations which provides that any licence issued under the 1997Regulations may permit a doctor to administer, supply or prescribe a drug, or to authorise the administration or supply of a drug, only while at an address specified in that licence. Regulation 4 makes transitional provision for licences issued under the 1997 Regulations before the coming into force of these Regulations and provides that such licences are to continue in force.
