Act 2009 and Regulations 28 and 29 of the Coroners (Investigations) Regulations 
2013.

INVESTIGATION and INQUEST 

On 29 September 2024, Assistant Coroner Stevens commenced an investigation 
into the death of Frederick Ireland-Rose aged 30 years.  The investigation 
concluded at the end of the inquest on 9 January 2025.  The conclusion of the 
inquest was: Mr Ireland-Rose died in hospital on 19 September 2024. Prior to his 
death, he had taken cannabis, and some medications sourced from outside the 
UK. It is unclear how he came to ingest a nitazene substance or whether he 
knowingly did so. It is possible that the nitazene was ingested by vaping.  

I returned a conclusion that Mr Ireland-Rose’s death was drug related.  

The medical cause of death was: 1a Hypoxic brain injury 1b Acute opioid toxicity 
(N-Pyrrolidino isotonitazene).

CIRCUMSTANCES OF THE DEATH 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 Mr Ireland-Rose had a history of opiate misuse. He was using cannabis and 
cannabinoid vapes to enable him to withdraw from opiates. He had been 
abstinent from opiates for about 10 days prior to his death and was well-
motivated to remain opiate free. On the afternoon of 15 September 2025, Mr 
Ireland-Rose was found unresponsive at his home with a vape in his hand. 
Paramedics were called and managed to resuscitate him using advanced life 
support techniques. He remained unconscious and was taken to hospital. His 
sedation was removed soon after admission and he never regained 
consciousness. A CT scan of his brain demonstrated diffuse hypoxic ischaemic 
encephalopathy which was not compatible with extended life. Mr Ireland-Rose 
died in hospital on 19 September 2024.   

Mr Ireland-Rose was known to purchase cannabinoid vaping fluids online from 
unknown sources outside the UK. Toxicology analysis found N-pyrrolidino 
isotonitazene at a level of 0.37 ng/ml in a sample of Mr Ireland-Rose’s blood. 
The Toxicologist reported that this is “a potent synthetic opioid” which is 
“thought to be similar or greater in potency to isotonitazene which is estimated 
to be approximately 20 times more potent than fentanyl”. The Toxicologist also 
reported that “nitazenes are illicit synthetic opioids which have recently 
emerged in the heroin supply in the UK”. There was no evidence to suggest that 
Mr Ireland-Rose had used street heroin prior to his death. The Toxicologist 
confirmed that nitazenes can be ingested from a vape and that they have been 
detected in refillable vapes and vapes bought illicitly.

CORONER’S CONCERNS 

During the course of the inquest the evidence revealed matters giving rise to 
concern. In my opinion there is a risk that future deaths could occur unless 
action is taken. In the circumstances it is my statutory duty to report to you. 

The MATTERS OF CONCERN are as follows.  –  

(1) The use of nitazenes as an adulterant to street heroin is well known. The 
presence of nitazenes in vaping fluids is less well known.  

(2) The level of nitazenes ingested by vaping will vary enormously depending on 
the frequency and extent of inhalations taken by the user. Consequently, the 
potential risk of overdose is significant.    

(3) Public health measures are in place through statutory and voluntary sector 
drug misuse services to inform heroin users of the risks of nitazene 
adulteration. Cannabinoid vape users will often not be known to drug services 
and therefore may not be aware of the risks posed by nitazenes in vape fluids.     

(4) Drug services often issue Naloxone to be used in the event of an 
opiate/opioid overdose. Cannabinoid vape users may not be aware of Naloxone 
or may have problems accessing it.

ACTION SHOULD BE TAKEN 

In my opinion action should be taken to prevent future deaths and I believe you 
and your organisation] have the power to take such action.

Dear Sarah Bourke, 

RE: Reg 28 Response: Frederick Ireland Rose 

Thank you raising the issue of nitazenes found in vapes with the ACMD. In July 2022 
the ACMD published advice on 2-benzyl benzimidazole (nitazene) and piperidine 
benzimidazolone opioids. 

The report has been updated by the ACMD five times through a series of 
addendums, with a further addendum due to be published later this year:  

•  First addendum – December 2022 
•  Second addendum – October 2023 
•  Third addendum – December 2023 
•  Fourth addendum – April 2024 
•  Fifth addendum – November 2024.  

The ACMD has a standing function to monitor emerging drugs, including new 
nitazenes variants and our standard operating procedure includes routes of 
administration within the consideration of harms. Vaping as a method of 
administration has also been raised as a concern in other recent ACMD reports. We 
have acknowledged the presence of nitazenes in vaping fluids and the need to 
monitor the detection of nitazenes in vapes and vaping fluid.  

In the above report, it was identified that nitazenes had been found in vapes and 
vaping fluids. In the same report the ACMD recommended improved toxicology and 
testing and increased funding to achieve this (see recommendations listed in the 
annex). The ACMD also recommended improved information for health professionals 
and the general public (including people who use both opioid and non-opioid drugs) 
on the health effects of synthetic opioids.  

I shall raise the concerns expressed in this Regulation 28 report to the Chair of the 
ACMD Novel Psychoactive Substances (NPS) Committee as well as at the upcoming 
ACMD Full Council meeting in October 2025, where members will discuss emerging 
issues.  

 
 
 
 
 
 
 
 
 
 
 
 
 I trust this provides you with assurances that the ACMD has made appropriate 
recommendations to the UK Government and continues to advise in this important 
area.  

Yours sincerely,  

 
 
 
 
 
 Annex – Recommendations made by the ACMD on nitazenes: 

Recommendation 1 
The following compounds should be added to Class A of the Misuse of Drugs Act 1971, 
consistent with the classification of other potent opioids. 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). 

•  Metonitazene 
•  Protonitazene 
Isotonitazene 
• 
•  Butonitazene 
•  Flunitazene 
•  Metodesnitazene (metazene) 
•  Etodesnitazene (etazene) 
•  N-Pyrrolidino-etonitazene (etonitazepyne) 
•  N-Piperidinyl-etonitazene (etonitazepipne) 
•  Brorphine 

Lead: Home Office 
Measure of outcome: The inclusion of the listed compounds in Class A of the Misuse 
of Drugs Act 1971 and schedule 1 of the Misuse of Drugs Regulations 2001. 

Recommendation 2 
The following compounds should be deleted from schedule 2 and added to schedule 
1 of the Misuse of Drugs Regulations 2001 (as amended). 

•  Etonitazene 
•  Clonitazene 

Lead: Home Office 
Measure  of  outcome:  The  inclusion  of  the  listed  compounds  in  schedule  1  of  the 
Misuse of Drugs Regulations 2001. 

Recommendation 3 
The ACMD recommends that a consultation should be undertaken with stakeholders, 
including academia and the chemical and pharmaceutical industries on the introduction 
of  a  generic  control  on  2-benzyl  benzimidazole  variants,  as  new  examples  may  be 
encountered  and  could  present  a  serious  risk  of  harm.  Following  this  consultation, 
materials covered by the generic should be added to Class A of the Misuse of Drugs 
Act 1971, consistent with the classification of other potent opioids. 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). 
The  proposed  wording  for  the  generic  for  addition  to the  Misuse  of  Drugs Act  is  as 
follows: 
[see most recent addendum published]  

Lead: Home Office 
Measure  of  outcome:  The  inclusion  of  the  described  compounds  in  Class A  of  the 
Misuse of Drugs Act 1971 and schedule 1 of the Misuse of Drugs Regulations 2001, 
following appropriate consultation. 

 
 
 
 
 
 
 
 
 
 
 
 
 Recommendation 4 
In light of the continuing emergence of NPS and particularly synthetic opioid NPS, a 
working group should be established to consider and provide recommendations on a 
UK-wide  minimum  standard  set  of  post-mortem  toxicology  tests  for  apparent  drug-
related  deaths,  to  include  testing  for  relevant  novel  psychoactive  substances  to 
improve  consistency  of  analysis  and  detection. The  best  practice  recommendations 
agreed would include standards for reporting. This working group should include (but 
not necessarily be limited to) representation from the following: 

•  Chief Coroner’s Office for England and Wales 
•  Coroners Service for Northern Ireland 
•  Crown Office and Procurator Fiscal Service Scotland 
•  UK and Ireland Association of Forensic Toxicologists 
•  London Toxicology Group 
•  Faculty of Forensic and Legal Medicine 
•  Office for Health Improvement and Disparities 
•  Home Office Forensic Early Warning System 
•  Police 
•  Local drug-related deaths review partnerships 
•  The ACMD 

Lead: Home Office 
Measure of outcome: A report  detailing best practice for forensic sample analysis in 
the investigation of apparent drug-related deaths 

Recommendation 5 
Adequate  funding  should  be  made  available  by  government  to  allow  coroners, 
procurators  fiscal  and  forensic  toxicologists  to  follow  the  best  practice  guidelines 
developed via Recommendation 4. 

Lead: Home Office 
Measure of outcome: Consistent and appropriate forensic analysis and reporting for 
suspected drug-related deaths across the UK. 

Recommendation 6 
Information for health professionals (such as TOXBASE) and the general public (such 
as Frank) on the health effects of NSO should be reviewed and updated, ensuring that 
information  is  available  in  an  appropriate  format  on  NSO  compounds  including 
benzimidazole and piperidinyl benzimidazolone opioids and the risks that result from 
the  inclusion  of  compounds  of  varying  and  sometimes  very  high  potency  in  heroin 
preparations and counterfeit medicines. 

Leads:  National  Poisons  Information  Service,  UK  Health  Security Agency,  Office  for 
Health Improvement and Disparities 
Measure  of  outcome:  Information  available  for  health  professionals  and  the  general 
public, including those with lived experience.

Dear Ms Bourke,   

, Chief 
Thank you for the Regulation 28 report of 6 June 2025 sent to Professor 
Medical  Officer at  the  Department  of  Health  and  Social  Care  (DHSC)  about  the  death  of 
Frederick Ireland-Rose. I am replying as the Minister with responsibility for Public Health and 
Prevention.        

Firstly, I would like to say how saddened I was to read of the circumstances of Mr Ireland-
Rose’s  death,  and  I  offer  my  sincere  condolences  to  their  family  and  loved  ones.  The 
circumstances  your  report  describes  are  deeply  concerning  and  I  am  grateful  to  you  for 
bringing these important matters to my attention.  

The Government is taking the threat from potent synthetic drugs, including synthetic opioids 
such as fentanyl and nitazenes, very seriously. Drug-related deaths are tragically at record 
highs, and we are committed to tackling this problem through working across health, policing, 
and wider public services. Your report raises concerns over the presence of synthetic opioids 
adulterating  other  substances  including  non-opioid  substances.  You  also  raise  concerns 
about  the  presence  of  synthetic  opioids  in  vapes  and  the  availability  of  naloxone  for 
cannabinoid vape users.   

To  enable  us  to  monitor  the  presence  of  synthetic  opioids,  DHSC,  alongside  other 
government departments, has a surveillance system in place which tracks changing drug 
markets  and  harms.  Within  this  system  we  have  established  several  new  data  streams, 
including  collection  of  toxicology  results  from  coroner  post-mortem  toxicology  labs,  and 
implemented a structured process for assessing the threat posed by synthetic opioids and 
other drugs. This process includes working closely with the Synthetic Opioids Taskforce in 
the  Joint  Combating  Drugs  Unit.  The  Synthetic  Opioids  Taskforce  works  with  partner 

 
  
  
  
  
  
  
  
  
  
  
  
   
   
  
 agencies such as the National Crime Agency (NCA) and the National Police Chiefs’ Council 
to counter the distribution and use of dangerous substances. Additionally, the NCA, working 
closely  with  policing,  Border  Force  and  international  partners  has  established  Project 
HOUSEBUILDER to ensure that lines of enquiry are prioritised and vigorously pursued to 
stem the supply of nitazenes and other synthetic opioids to and within the UK.  

Based on our long-standing  surveillance,  vape  liquids  containing nitazenes  are  extremely 
rare, with no confirmed casualties attributed. However, fake medicines containing synthetic 
opioids  have  become  more  common  and  have  recently  caused  several  deaths.  This  has 
especially  been  the  case  among  people  buying  them  online  for  the  purpose  of 
selfmedication.  The  nitazene  found  in  Mr  Ireland-Rose’s  examination,  n-pyrrolidino 
isotonitazene, is one of a number of common adulterants in fake oxycodone tablets, which 
are often bought online.   

Where there are incidents of synthetic cannabinoids in THC vapes, the local authority public 
health  team  and  the  police  force  should  act  with  partners  to  warn  and  protect  their 
communities. The Government also provides funding to National Trading Standards to crack 
down on illegal sellers and undertake testing of products.  

To  further  combat  the  threat  of  synthetic  opioids,  including  their  presence  within  fake 
medicines, a number of legislative changes have been implemented. On 20th March 2024, 
the UK controlled 15 named synthetic opioids (14 nitazenes) under Class A of the Misuse of 
Drugs Act 1971. Class A drugs are the most harmful substances and consequently carry the 
highest  sentencing  tariffs.  Additionally,  on  15th  January  2025,  a  generic  definition  of 
nitazenes as Class A substances, became law. This aims to prevent drug gangs from trying 
to adjust drug recipes to attempt to bypass UK drug law. This means that anyone caught 
producing or supplying nitazenes could now face up to life in prison, an unlimited fine, or 
both. The Government will continue to take an agile approach to legislating against synthetic 
drugs, and we remain alert to the need for changes.   

Alongside  legislative  changes,  this  Government  has  also  published  guidance  for  local 
commissioners and service providers on planning to deal with, and responding to, potent 
synthetic  opioids.  Furthermore,  the  report  ‘Local  preparedness  for  synthetic  opioids’. 
provides evidence and insights for Combating Drugs Partnerships to help strengthen their 
preparedness for an evolving threat.   

Your report also raised concerns about availability of naloxone for cannabinoid vape users. 
DHSC has an action plan to reduce drug and alcohol-related deaths which includes widening 
the availability and access to naloxone.  Last year, the Government amended the Human 
Medicines  Regulations  2012  to  expand  access  to  naloxone.  The  legislation  means  more 
services  and  professionals  can  supply  this  medication  without  prescription,  which  in  turn 
means easier access to it for people at risk, and for their loved ones. DHSC has recently 
published  guidance  that  sets  out  essential  practical  information  such  as  who  can  supply 
naloxone, the products available, how to use naloxone and other basic lifesaving tools, and 
the training required.  

Raising  awareness  of  naloxone  and  its  lifesaving  potential  among  the  general  public  is 
important. The Government has a drug and alcohol information and advice service called 
FRANK. This aims to reduce drug and alcohol use and their harms by providing information 

  
  
  
  
  
  
 and increasing awareness for young people, parents, and concerned others. The FRANK 
website has a page providing detailed information on when and how to use naloxone, which 
link:  https://www.talktofrank.com/get-help/what-to-do-in-
is  available  at 
anemergency.  

following 

the 

There  is  no  doubt  that  illicit  drugs  have  a  devastating  impact  on  our  communities.  This 
Government will continue to respond and adapt to the changing landscape of threats caused 
by  synthetic  opioids.  These  harms  are  preventable,  and  this  Government  is  committed, 
through our Health Mission, to ensure people live longer, healthier lives. I hope this response 
is helpful. Thank you for bringing these concerns to my attention.  

Yours sincerely,   

PARLIAMENTARY UNDER-SECRETARY OF STATE FOR PUBLIC HEALTH AND  
PREVENTION
