Section 7(3) of the Misuse of Drugs Act 1971 requires regulations to be made to allow the use for medical purposes of the drugs which are subject to control under that Act. Section 7(3) does not apply to any drug designated by order under section 7(4) as a drug to which section 7(4) is to apply. This Order amends the Misuse of Drugs (Designation) (England, Wales and Scotland) Order 2015 (S.I. 2015/704) by inserting a synthetic opioid (U-47,700), several methylphenidate related materials and a number of designer benzodiazepines into Part 1 of the Schedule to that Order.
