Making drug policy together:
Reflections on evidence, engagement and politics
Key words: consultation, engagement, evidence, evidence-base, politics
Abstract
This commentary considers the relationship between evidence, engagement and
participation in drug policy governance. It argues that the use of various forms of
evidence (for example, statistical data and service user narratives) is critical for
meaningful stakeholder engagement and public participation in drug policy, as well
as effective policy design and implementation. The respective roles of these different
kinds of evidence in consultation processes need to be better understood. It
discusses the limits of evidence, which it suggests is rarely conclusive or decisive for
drug policy. This is partly because of the incompleteness of most research agendas
and the lack of consensus among researchers, but also because issues in drug
policy are inherently contestable, involving considerations that lie outside the
competency of drug policy specialist as such. In particular, this is because they
involve normative and evaluative issues that are properly political (for example,
about the relative weight to be accorded to different kinds of harm and benefit). It
concludes by supporting calls for a more nuanced undertstanding of the relationship
between evidence, engagement and politics than is implicit in the term ‘evidence
based policy’. It also argues that we should view the inherent contestability of drug
policy not as something that can or should be resolved by ‘objective’ evidence, but
as a source of vitality and creativity in policy development and evaluation.

Making drug policy together:
Reflections on evidence, engagement and participation
The report How to make drug policy better (UKDPC 2012a) identifies a number of
governance issues, including ‘better use of evidence’, ‘accountability and scrutiny’
and ‘stakeholder engagement’. So, how do they fit together?
In my UKDPC essay on ‘Consultation processes and good governance’ (Roberts M,
2012) I raised this question with reference to the role of public consultation and
engagement processes in drug policy governance. On the one hand, consultation is
intended to inform policy by helping to provide the evidence-base for policy
development. On the other, it provides an opportunity for representation of the views
and experiences of a range of individuals and organisations who are interested in
and/or affected by drug policy. I linked this to a distinction between two principles of
public engagement. First, a principle of fairness or inclusiveness in the distribution of
opportunities for participation. Second, a principle of competence or robustness in
determining the value of different contributions, requiring qualitative distinctions
between the views of participants (or, more accurately, of the experience, evidence
and/or argument that support them).
I am now less sure that this is necessarily a helpful way to describe the issues, and
would like to indicate how some of the apparent tensions might be creatively
managed in the interests of good policy governance. For simplicity’s sake, this could
be described as a discussion of the relationship between ‘evidence’, ‘engagement’
and ‘participation’, and as a challenge to a particular view of how this relationship
should work: that the purpose of public consultation and engagement is to provide
Page 4 of 19

the evidence-base to determine policy at the political level. By contrast, I will sketch
out the lineaments of an argument for what might be described as ‘evidence
informed pluralism’ with a strong emphasis on the need for on-going and iterative
policy processes (and – although I don’t discuss it here – for engagement
mechanisms that nurture and support discussion, learning and recalibration of policy
in the light of the lessons from implementation).
The nature of evidence
Three initial observations about evidence and drug policy.
First, a particularly high premium appears to be placed on evidence-based policy in
fields like drug policy and criminal justice, and this is partly because drug policy is
believed to be particularly susceptible to misinformation and to emotional responses.
For example, the UK Drug Policy Commission’s A Fresh Approach to Drugs
observes that ‘the debate about how we address the challenges of mind-altering
drugs is polarised and with an added emotional and moral aspect that is not seen in
most other policy areas’ (UKDPC, 2012b, p. 8). This is compounded by the
stigmatisation of individuals, families and communities affected by drug problems,
which is fed by commonly held but often false or exaggerated beliefs. As the UK
Drug Policy Commission report How to make drug policy better observes this is also
a consideration in the design of consultation processes as ‘people with drug
problems are a highly stigmatised and marginalised group and they may be excluded
or “drowned out”’ (UKDPC 2012a p. 39).
Second, different forms of evidence will be relevant to different kinds and stages of
drug policy development and implementation, and these involve different forms of
competency and expertise. For example, evidence from analyical toxology or
Page 5 of 19

neuropsychopharmacology is different in kind to economic analysis of the cost-
benefit ratio of a policy initiative or to a qualitative analysis of its impact within a local
community. There is a particularly fraught question about how research evidence
derived (for example) from clinical trials and research studies is balanced with
‘narrative evidence’ from service users. This is particularly pertinent given the
importance of narrative in service-user led recovery movements in mental health and
substance misuse that have challenged dominant treatment models even where
these are believed to be well-supported by medical and clinical evidence-bases. Nick
Tilley highlights the potential for ‘the discourse of user empowerment’ to collide ‘with
the other key driver of contemporary health and social policy – evidence-based
policy’ (Tilley N, cited in Cook 2002, pp. 526-7). In a similar vein, Mark Monaghan
writes that ‘devolving … decision(s) to experts … could be seen as an abrogation of
the principles of democracy and a step along the way to technocratic decision-
making’, with the risk – citing Weingert – that politics is ‘replaced by scientifically
rationalised administration’ (Monaghan M 2012, p. 54).
Third, one of the least likely things you’ll hear from a specialist researcher is that the
evidence for something is complete, unambiguous and points to a single policy
conclusion. In other words, the call for evidence-based policy is at least as often a
plea to be mindful of what we don’t know as to build on what we do. A related issue
is the need to reconcile the interest in evidence-based approaches to drug policy
issues with calls for innovation (particularly in drug treatment provision). A particular
issue for analysis of the likely impact of policy is the problem of unanticipated and
unintended consequences, which the philosopher Karl Popper (1902-1994)
described as ‘the characteristic problem of the social sciences’. Put crudely, one

thing we know about policy is that it will tend to produce consequences that were not
predicted by evidence available at the point of implementation.
The role and limits of evidence
There are issues in drug policy that are (in a more or less broad sense) ‘scientific’ or
‘technocratic’ and ought therefore to be entrusted to the relevant expert
communities. These include the chemical compositions of psycho-active substances;
their physiological and psychological effects, including potential risks; the
relationship between clinical interventions (such as needle exchange, substitute
prescribing or psycho-social interventions) and treatment outcomes (such as
retention in services, transmission of blood borne viruses like HIV and hepatitis or
levels of offending); and analysis of the cost-benefit of policy approaches (for
example, in the UK it has been calculated that every £1 invested in drug treatment
saves £2.50 in subsequent costs arising from a failure to intervene).
While these kinds of evidence can frame and inform policy development, they will
rarely be decisive; policy conclusions can seldom (if ever) be rationally derived from
an uncontested evidence-base.
For a start, and as highlighted above, there is rarely consensus in research and
specialist communities. For example, the relationship between drug dependence and
crime – critical for cost-benefit calculations - is an area of controversy amongst social
scientists. Mark Monaghan writes that ‘one of the true stumbling blocks to the
realisation of evidence-based policy is that the “evidence” is rarely definitive. Indeed,
one of the paradoxes of research in any given area is that the more heavily
something is researched, the less there is convergence on points of agreement’
(Monaghan M 2012, p. 53). Evidence about the composition, effects and risks of

particular drugs may appear less susceptible to controversy, but often the evidence
here is provisional and contestable about causal relationships and longer-term
effects (for example, on cannabis and mental health), and increasingly policy is
addressing an explosion in new psychoactive substances about which there is little
or no scientific evidence. Policy makers are having to address issues about risk in
(and, indeed, because of) the absence of reliable evidence.
There is an historical case to be made that a particular emphasis on ‘evidence based
policy’ emerged in the 1990s in the UK partly as a reaction by what might loosely be
described as the progressive left to a political environment that was inhospitable to
its values. On this view, the political ideology could be stripped out of policy making
and replaced with ‘objective scientific evidence’ demonstating ‘what actually works’
and persuading any rational person to accept the preferred policy solution, and
which it was believed would fortuitously support progressive policy on issues like
crime and punishment and drug policy. There is much to commend this approach: in
the UK it is widely accepted that it drove and legitimised an unprecedented
expansion in the availability of drug treatment provision. But, in reality, it is
impossible to cleanse policy debates of values, even where these can be concealed
more or less successfully for a while. The repressed has a habit of returning.
In the UK, for example, a group of scientists led by Professor David Nutt (currently
Edmond J Safra chair in neuropsychopharmacology at Imperial College London)
published an influential article in The Lancet called ‘Drug harms in the UK: a multi-
criterion decision analysis’, which ranked alcohol as the most harmful drug, followed
by heroin, and with ecstasy and LSD among the least harmful (Nutt D et al 2010).
This research was widely heralded for taking a scientific approach to the emotive
issue of drug harm, and so it did to a significant extent; however, it was also heavily
Page 8 of 19

reliant on subjective evaluations. In addition, it considered 16 forms of harm,
including drug-related mortality, drug dependence, crime and social cohesion. There
is no scientific way of weighing these various harms using a single objective
standard of commensuration, as its authors acknowledged.
The same sort of issue arises with the campaign currently being led by the pro-
reform group Transform in the UK for the development of ‘an objective mechanism
for assessing the relative merits of different policy approaches, by developing a
genuinely evidence-based Impact Assessment of Drug Policy that compares the
impact of alternative policies on human development, human security and human
rights’ (Transform website, 10 October 2013). There will be an extraordinarily wide
range of harms and benefits that will need to be balanced against each other. Nor
will harms or benefits be distributed equally between individuals or communities,
requiring a balancing of different and potentially competing interests. It’s also very
complicated. The Beckley Foundation report A regulated cannabis market in England
and Wales – Towards a cost-benefit analysis [emphasis added] looked at ‘seventeen
distinct sources of social cost or benefit’, concluding that ‘at present there is so much
uncertainty about some of the important issues involved in the introduction of a
licensed and regulated cannabis market that a clear conclusion is not possible’
(Bryan M, Del Bono E and Pudney S 2013, p. iv). This study considered a single
drug in a single jurisdiction, these uncertainties would be considerably magnified for
any attempt at a global impact assessment.
To take another example, New Zealand’s Psychoactive Substances Act 2013 has
been heralded as ‘a pragmatic and evidence-based approach to recreational drug
use’ (Wood J and McCullough C, 2013). This law regulates the production and sale
of new psychoactive substances by placing the onus of proof on manufacturers to

demonstrate that they are ‘low risk’ before they can be legally sold, with each
product required to go through a clinical testing process. But what is ‘low risk’ (and,
incidentally, how will this process identify longer term risks)? As Mike Power has
observed ‘all drugs, it could be argued, have a toxic effect: that’s the point. This is a
key issue for the NZ legislation: set the harm threshold too low, and it’s prohibition
redux. Too high and dangerous substances can be sold legally’ (Powers M, 2013).
Setting a benchmark for the ‘low risk’ threshold is critical for the implementation of
this ‘evidence-based approach’. This is not a scientific issue but a normative - and
properly political - issue.
In conclusion, drug policy issues share many of the characteristics of so-called
‘wicked problems’. Kane and Bishop note that these issues are ‘frieghted with
diverse and sometimes incompatible opinions and interests’, such that ‘consensus
among them may in the end prove impossible’ (Kane J and Bishop P 2002, p. 89).
Mark Monaghan observes that ‘wicked problems’ arise in ‘areas of policy that defy
neat solutions as there is little agreement on the nature of the problem in the first
instance’ (Monaghan M 2012 p. 50). Consider, for example, two recent discussions
of the role of Opiate Substitution Treatment (OST) in the UK. A study commissioned
by the Department of Health concluded that among the benefts of OST are that it
‘prevents people dropping out of treatment’ (National Treatment Agency 2012, p.
24); by contrast a report by the Conservative supporting thinktank the Centre for
Social Justice decries ‘a fatalistic drug treatment system which [has] trapped many
thousands of addicts in state-sponsored dependency’ (Centre for Social Justice
2013, p. 5). These are very different assessments in terms of their tone and
conclusions, but how far is this a disagreement about objective evidence and how
Page 10 of 19

10
much does it reflect a lack of ‘agreement on the nature of the problem in the first
instance’?
Evidence, engagement and participation
As Dee Cook observes, ‘consultation, participation and empowerment are
processes which are problematic and challenging for researchers, practitioners and
policy makers alike … developing appropriate tools and recognising that consultation
is a process not an event are essential starting points’ (Cook D 2002, p. 530). Such
engagement processes can occur at a number of stages in a policy process
including initial scoping of options, policy design, implementation and evaluation.
They may serve a range of purposes including gathering evidence, listening to
community concerns, reconciling interest groups, involving service users, evaluating
policy options and assessing the impact of policy implementation. They may include
a range of engagement processes including formal written consultation exercises,
face-to-face meetings between lobby groups and decision-makers, consultative
events with stakeholders, advisory groups, commissioned research and relatively
new and innovative approaches such as deliberative polls and citizens juries. These
can all involve a range of interlocuters including think tanks, representative and
campaigning bodies, researchers and statisticians, service commissioners, service
providers, service users, families, community groups, residents affected by a
particular issue or policy and the public as a whole.
Different approaches to consultation will be appropriate to different issues and at
different stages. An engagement process to consider options for drug law reform will
require a different approach to clinical assessment of a medical intervention or
Page 11 of 19

ted

11
consultation on configuration and delivery of a local drug treatment system. Different
kinds of competence, knowledge and experience will be relevant to different kinds
and stages of consultation. For example, only those with certain kinds of expertise
are qualified to contribute meaningfully to a cost-benefit assessment or a clinical
assessment. In this sense, a ‘principle of inclusiveness’ is not necessarily in conflict
with a ‘principle of competence’. Fairness may require that everyone affected by a
policy is included in the scope of engagement processes, but because this is about
engaging each on the basis of their particular expertise or experience there is no
necessary tension with competence. It is not necessary or desirable for every stage
or aspect of a consultation process to be inclusive. For example, an expert on
toxicology or pharmacology should not expect to be consulted on community impact
of a drug service nor a community leader on the pharmacological properties of a
certain drug.
Considering drug policy as a whole, competency should not be conceived in binary
terms but in terms of the particular competencies that different contributors bring to
different stages and aspects of the process in virtue of their knowledge and
experience. The professor or politician will defer to the drug worker or service user
where their views and experiences are most pertinent, and vice versa – everyone is
committed to listening as well as talking. Thus Nick Tilley observes that evidence in
the narrow sense is critical to inform policy formation and implementation, but that an
'evidence-led agenda' promises 'too strong a role for evidence' (cited in Cook D 2002
pp. 526-7). As a corrective to an overly technocratic approach, he emphasises the
importance of theorising based on experience of contexts, mechanisms and
outcomes, as distinguished from generalisable evidence from Randomised

Controlled Trials. The focus should be on achieving 'an improved grasp on what
worked, how and with whom within the process' (ibid).
As previously noted there is a particular issue about the balance between research
evidence and the narrative testimony of service users and others directly affected by
drug policies. It may be useful to distinguish between, on the one hand, anecdotal
evidence in which – for example - a research conclusion is dismissed or rejected on
the basis of a single counter-example from personal experience (the Uncle who
smoked 60 a day and lived to be 100) and, on the other hand, narrative evidence
where experience is described on a person’s own terms to provide a finely textured
and personally and emotionally engaged account of their experience.
Research is selective in its scope and relevant experience will escape the
searchlight it throws on an issue at a particular time and driven by a particular
agenda. For example, research on a treatment intervention will screen out a lot of
other things that are going on in a person’s life which may be critical for them (for
example, the impact of a positive relationship, an activity or loss of work or housing).
Consider, at extreme ends of a continuum, the contrast between a first person
narrative and the bare statistical datum that X has been ‘retained in treatment’ for six
months. Research will operate at various points across this spectrum, and
sophisicated research will account for a wide range of factors like relationships and
employment, but it will not (and is not intended to) extend to the totality of an
individual’s experience and its particular meaning and significance for that person
(unless perhaps in the form of narrative testimony within a qualitative process).
Narrative evidence can push research and policy outside of its current frameworks
and ‘comfort zones’ and provides a catalyst for fresh thinking. The issues about
Page 13 of 19

ted

uscr
ipt
13
balancing research evidence with first person testimonies are not straightforward.
There are challenges in designing engagement processes that enable service users
to contribute on their own terms, while giving due weight to other evidence. Dee
Cook observes 'that while government does indeed "talk the talk" on consultation, it
has yet to persuade many that it will "walk the walk". If the objects of social policy -
service users, the poor, powerless and disaffected - were to find their voice, the talk
itself may become unpalatable’ (Cook D 2002, p. 529).
A further issue is what might be described as ‘competency drift’. There has been a
tendency for drug policy experts to presume special competency (often implicitly)
with respect to matters that are normative or political issues. These are not issues in
drug policy, but they are critical for drug policy. Drug policy specialists as such have
no unique competence to pronounce on the value that should be accorded to
different kinds of harms and benefits in assessing policy options; the allocation of
scarce resources between priorities (for example, drug treatment and social care); or
the levels of risk to which governments expose citizens or markets pass to
consumers. It is with respect to such questions that there is potential to develop
mechanisms for informed public and community debate such as deliberative polling
and citizens juries. Participants are not policy specialists: their role is not to provide
evidence or expertise to inform decision-makers, but to engage in deliberative
processes where they reflect on evidence and make policy or practice
recommendations.
There are wider issues about the relationship between stakeholder consultation and
policy and political processes, particularly in democratic systems, which go back to
Monaghan’s point about the risks of ‘technocratic decision-making’. In ‘Consultation
and Contest’, John Kane and Patrick Bishop highlight the dangers of ‘talk[ing] up
Page 14 of 19

ted

ipt
14
consultation as a democratic device’, which they argue is inconsistent with the
principles of representative democracy for which ‘a policy is legitimate if it has been
made by the appropriate authority after due consideration of the various interests
and opinions that exist amongst the public’ (Kane J and Bishop P 2002, p. 89). They
conclude that ‘a representative government should never (save in a referenda) allow
citizens to believe that their input in policy questions will be determinant of final
decisions’ (ibid). Helena Catt and Michael Murphy note that ‘consultation, by
definition, is not decision-making’, but a process that can inform it; it is therefore
important to distinguish between ‘the range of situations where the government gives
a voice in making decisions while on the other side are all the instances where the
group is involved in advising or providing information for the decision makers’ (Catt H
and Murphy M 2003, p. 415).
Conclusion
The purpose of this commentary has been to highlight the complex relationships
between evidence, engagement and participation and the 'wicked' nature of drug
policy issues. It has moved freely between different levels and kinds of policy
development, from drug law reform to service development at local level, further
complicating the picture. It is beyond its scope to propose solutions in terms of
specific mechanisms for drug policy governance, but I hope it has helped to raise
some relevant questions and considerations.
Firstly, there is the question of how to balance issues of competence with principles
of inclusivity in drug policy development. Everyone must have some form of
'competency' in order to have a legitimate claim to inclusion in consultations, but the
basis and nature of those competences will be varied. This is an important
Page 15 of 19

ted
Man
uscr
ipt
15
consideration in the design of participatory mechanisms. It also helps to address
concerns about 'technocratic decision making', because it means that even if
governance and participatory processes were designed with a focus on 'expertise'
they should tend to inclusivity if they have worked with an appropriately broad
understanding of relevant forms of expertise (for example, drug service users as
'experts by experience'). In addition, pluralistic and inclusive approaches will tend to
produce more robust forums for the interrogation of research claims and policy
proposals, so long as these forums are framed by principles of reciprocity and
respect for the diverse competences and points of view of different interlocutors.
Second, there is a related issue about the role of specialist competences (including
scientific expertise) in democratic processes, which is not specific to drug policy, but
applies across the policy spectrum. It has been suggested that meaningful and
empowering democratic decision-making requires that all participants are equipped
with the tools to make informed choices about key policy issues, including to predict
as far as possible the probable consequences and impact of different decisions that
they could make (as well as understanding the risks and uncertainties). Without this
political choice is meaningless. It follows that genuinely inclusive and participatory
drug policy processes will not be meaningful without adequate investment in
research, in information and education, and in the effective dissemination of
knowledge. This raises issues about the responsibilities of public figures and the
media to ensure they are not legitimising false or misleading perceptions and
information. Again, the general principles of inclusiveness/democracy and
competence/expertise are not in conflict on inspection but, on the contrary, are
interdependent. In practical terms, consultative mechanisms such as citizens juries
could provide an effective model for this kind of political decision-making.

16
Third, it has been suggested that a threat to effective pluralistic approaches to drug
policy development - and the cultures and relationships that sustain them - is
'competency drift'. On the one hand, this occurs when political exigencies influence
the interpretation or presentation of evidence, which may not be conscious or
deliberate. On the other hand, it occurs when drug policy expertise is regarded as
providing a privileged basis for pronouncing on issues to which it may not be directly
relevant, including aspects of some of the most critical and contested issues within
drug policy - for example, pertaining to law reform and investment in drug services
given competing priorities. Once again, this suggests that there is no inherent conflict
between a commitment to evidence based policy and respect for the role of
representative government in making ultimate decisions about policy issues, so long
as issues of respective competencies are respected, negotiated and managed.
Finally, the scope of evidence to determine policy and it's implementation is critical
but also limited. This is not only because evidence is incomplete and often
contested by the relevant expert and professional communities, but also because
drug policy inevitably involves normative considerations that are not resolvable by
'evidence'. We should therefore reject models of evidence informed policy
development which assume that the gradual accumulation of more evidence will
necessarily provide a fully rational basis for resolving policy disagreements or point
us unambiguously to a particular policy solution. It would be a useful project to make
explicit the values implicit in drug policy positions and their relationship to matters of
evidence and to consider how we would create space for rational debate of these
underlying ideas, drawing on disciplines like moral philosophy and political
psychology. It is likely, however, that many of these issues would turn out to be
Page 17 of 19

ted

uscr
ipt
17
general moral and political questions and not drug policy specific - for example,
about individual liberty or the role of markets or the responsibility to reduce harms.
Evidence, then, should be at the core of drug policy development and governance,
and is indispensible for meaningful participatory and democratic processes, but it will
also tend to be partial, provisional, contested, incomplete and open to revision – and
many of the key issues for drug policy are not in principle amenable to purely
evidential solutions because they have a normative aspect. There is often an implicit
assumption that rational governance processes should produce a reasoned
consensus on a policy solution (and residual opposition will reflect lack of
acquaintance with evidence or a failure of rationality). But many of the key issues in
drug policy are inherently contestable. While evidence will rule out a range of options
and shape many others it will rarely point unambiguously to one solution or approach
– there is much that is provisional and contestable. This is something we might
perhaps learn to embrace. John Stuart Mill (1806-73) observes that where an
opinion ‘is not fully, frequently and fearlessly discussed, it will be held as a dead
dogma, not a living truth’ (J S Mill, On Liberty). Policy consensus can be followed by
ossification, as an idea loses its vitality and radical force and is reduced to jargonese
and subject to formulaic or bureaucratised forms of implementation.
More prosaically, engagment and consultation processes need to be on-going and
open-ended because the evidence-base changes and develops as new research
becomes available, old evidence is reviewed and reinterpreted, and different stages
are reached in policy design, development, implementation and review – the wider
environment in which policy is developed and implemented changes too of course
(for example, the financial context, political climate or policy in closely related areas
like welfare or housing).

One final point, effective stakeholder engagement and the development of
participatory processes is likely to be a resource-intensive business for both
consultors and consultees – there are significant opportunity costs in diverting
resources away from other activities, including providing services or developing
research projects. What is the cost-benefit of good governance – and is it worth the
candle at a time when resources are being squeezed in many jurisdictions? Part of
the answer is that unless sufficient investment of time and resource is made to
ensure consultation and participatory processes are genuinely meaningful with
demonstrable impact on decision making there will be a tendency for key voices and
constituencies to disengage from these processes, undermining the pluralism upon
which the sort of approach that has been outlined here depends.
