These Regulations amend the Misuse of Drugs Regulations 2001 (“the Regulations”). The schedule to the Regulations 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. The controlled drugs placed in Schedule 1 to the Regulations are those subject to the tightest controls.
