The Misuse of Drugs (Amendment) (England, Wales and Scotland) Regulations 2011
These Regulations amend regulation 4B of the Misuse of Drugs Regulations 2001 (the “2001 Regulations”) by including within the reference to 1,4-butanediol in regulation 4B any substance which is an ester or ether or both an ester and an ether of 1,4-butanediol, and by removing from the references to gamma–butyrolactone and 1,4-butanediol any stereoisomeric form of gamma–butyrolactone and 1,4-butanediol respectively. Regulation 4B was inserted into the 2001 Regulations by regulation 3 of the Misuse of Drugs (Amendment) (England, Wales and Scotland) Regulations 2009, and makes it lawful to import, export, produce, supply, offer to supply or possess gamma‑butyrolactone and 1,4‑butanediol except where a person does so, knowing or believing that it will be used for the purpose of human ingestion other than as a flavouring in food.
