COMMISSION TO THE ACMD – LONGER TERM REVIEW OF CANNABIS-
BASED PRODUCTS FOR MEDICINAL USE IN HUMANS 
 
 
Background  
 
On 03 July, I commissioned the Advisory Council on the Misuse of Drugs (‘the 
ACMD’) to advise on part-two of the review on cannabis and cannabis related 
products. The commission sought the views of the ACMD on the rescheduling 
of cannabis under the Misuse of Drugs Regulations 2001 (“the 2001 
Regulations”) and any other mitigating action to prevent the risks of misuse 
and diversion. The ACMD were asked to provide advice within three weeks 
and twelve months of the commission.  
 
The ACMD issued their short-term advice on 19 July and 11 September with a 
set of recommendations for both the Home Office and the Department of 
Health and Social Care (‘DHSC’). On 1 November, cannabis-based products 
for medicinal use were added to Schedule 2 under the 2001 Regulations.  
 
The purpose of this commission is to ask the ACMD to commence the longer-
term review of cannabis-based products for medicinal use.  
 
In doing so, the ACMD should not review or consider any of the following 
which fall under the Misuse of Drugs Act 1971:  
  
a) The classification of cannabis as a Class B drug under Schedule 2, 
Part II;  
b) Any associated criminal offences for cannabis as summarised in 
Schedule 4;  
c) The cultivation of the cannabis plant under section 6(2) or the 
cultivation under a licence of the cannabis plant under Regulation 12 of 
the 2001 Regulations (irrespective of the THC content of the seed or 
variety of the plant). 
 
The commission is split into three components and is as follows:  
 
Monitoring/Assessment of the impact of the change in legislation on 
cannabis-based products for medicinal use 
 
a) As part of this review can the ACMD: 
 
i. provide an outline for an assessment framework. This should set 
out how the ACMD will assess the various impacts of rescheduling 
cannabis-based products for medicinal use to Schedule 2 under 
the 2001 Regulations, and the data sources (including those 
provided by the Home Office and DHSC) the ACMD will use by 
November 2019?

ii. Carry out an assessment of the impact of the legislative change 
and report its findings and any recommendations to mitigate the 
issues identified by November 2020?   
 
Synthetic cannabinoids 
 
The current definition of synthetic cannabinoids in the Misuse of Drugs Act 
1971 and the Misuse of Drugs Regulations 2001 is provided at Annex A. 
 
The ACMD provided its last report on the harms of the third-generation 
synthetic cannabinoids in November 2014. In the ACMD’s initial advice on the 
short-term commission dated 19 July 2018, the ACMD recommended that 
synthetic cannabinoids remain in Schedule 1 of the 2001 Regulations pending 
their longer-term review.  
 
On 6 November, the Minister for Policing and the Fire Service committed to 
asking the ACMD for a refresh of its 2014 assessment on the harms 
associated with synthetic cannabinoids and provide necessary advice on this 
issue. This follows the concerns raised by Members of Parliament and by the 
police and crime commissioners on the current classification of synthetic 
cannabinoids under the Misuse of Drugs Act 1971 (“the 1971 Act”).  
 
a) As such, can the ACMD provide the following by Summer 2020? 
 
i. an updated harms assessment to the ACMD’s previous reports 
on synthetic cannabinoids. 
 
ii. its recommendation on whether the current classification under 
the 1971 Act of synthetic cannabinoids listed in Annex A is 
appropriate.  
 
a. If not appropriate, can the ACMD provide their 
recommendation on whether all or some synthetic 
cannabinoids should be reclassified under the 1971 Act?  
 
b. If reclassification is recommended, can the ACMD advise 
on the appropriate reclassification? 
 
iii. its recommendation on whether the current scheduling under the 
2001 Regulations of synthetic cannabinoids listed in Annex A is 
appropriate.  
 
a. If not appropriate, can the ACMD provide their 
recommendation on whether all or some synthetic 
cannabinoids should be rescheduled under the 2001 
Regulations? 
 
b. If rescheduling is recommended, can the ACMD advise 
on the appropriate rescheduling?

Cannabis-based products for medicinal use  
 
a) As part of the longer-term review can the ACMD provide, by 
November 2020, their full advice on:  
 
i. whether the scheduling of products which currently fall under the 
definition of cannabis-based products for medicinal use is 
appropriate 
 
ii. If not, can the ACMD advise on the appropriate rescheduling?  
 
iii. whether any further legislative amendments regarding cannabis-
based products for medicinal use are required under the 2001 
Regulations.
