Dear Owen and David,

The Government response to the ACMD advice on diphenidine and related substances.

I am grateful to the ACMD for their advice on diphenidine and its related substances. I have set out each recommendation and the Government’s response below:

Recommendation 1:

The ACMD recommend the compounds diphenidine, ephenidine and methoxyphenidine (also known as methoxphenidine) should be added to Class B of the Misuse of Drugs Act 1971, consistent with the classification of ketamine and other controlled dissociatives such as methoxetamine and PCP-related materials.

Government response

The Government accepts this recommendation and intends to bring forward legislation to implement it, subject to Parliamentary approval.

Recommendation 2:

As these materials have no medical use it is recommended that they should be placed in Schedule 1 of the Misuse of Drugs Regulations 2001 (as amended) and added to Schedule 1 of the Misuse of Drugs (Designation) (England, Wales and Scotland) Order 2015, to which section 7 (4) of the Misuse of Drugs Act 1971 applies.

  • Diphenidine
  • Ephenidine
  • Methoxyphenidine (also known as methoxphenidine)

Government response

The Government accepts this recommendation and intends to bring forward legislation to implement it, subject to Parliamentary approval.

Thank you again for your advice.

Yours sincerely,

Rt Hon Chris Philp MP

Minister of State for Crime, Policing and Fire
