The Misuse of Drugs (Amendment No.2) (England, Wales and Scotland) Regulations 2010
These Regulations insert a further group of cathinone derivatives (including naphthylpyrovalerone, commonly known as naphyrone) into Schedule 1 to the Misuse of Drugs Regulations 2001. The schedule in which a controlled drug is placed primarily affects the extent to which the drug can be lawfully imported, exported, produced, supplied or possessed and dictates the record keeping, labelling and destruction requirements in relation to that drug.
