Impact of stigma on people with opioid use disorder


Opioid use disorder is a global health issue, with more than 40 million people estimated to be using opioids in 2017.1 Illicit drug use disorders are the most stigmatised health conditions worldwide, and compared to other mental or physical health problems are more likely to be viewed as a personal choice or a sign of weakness or “bad character”.2 People with opioid use disorders are often perceived as dangerous and unpredictable, subject to high levels of social exclusion, and may be considered unworthy of receiving government assistance with food or housing.3–5

However, the ways in which opioid-related stigma is enacted are complex and vary depending on the type of opioid, how it is acquired, and the context of use. As noted by McCradden et al,6 an unstable dichotomy exists between “legitimate” use of opioids (ie, medically sanctioned treatment, usually for an objective pathology) and “illegitimate” use (ie, use for recreational purposes or in response to psychological stressors). People who inject illicit opioids tend to be the most stigmatised: although few studies have examined stigma, opioid use, and injecting drug use concurrently, both illicit drug use and intravenous routes of administration are associated with more negative public attitudes and greater barriers to accessing health services.5,7,8 Fentanyl use also attracts a high level of stigma, which may be compounded by increased media coverage of overdose deaths with narratives framing the individual as problematic and dangerous (while de-emphasising the responsibilities of health care systems and the pharmaceutical industry).9 There is also widespread misinformation among first responders regarding the risks of passive exposure to fentanyl, which may lead to unnecessary precautions that hinder effective overdose response, and entrench beliefs that people who use illicit opioids are dangerous and should be avoided.10,11

Substantial increases in opioid prescribing for chronic non-cancer pain over the past 20 years have led to considerable harms, including morbidity and mortality due largely to accidental overdoses. Unlike illicit opioid use and opioid use disorder, media coverage of this issue is less likely to rely on long-standing negative stereotypes about drug users,12,13 and people who become addicted to prescription opioids may be conceptualized as having a physical disease rather than being personally responsible for their condition.14 Nonetheless, they face high levels of social exclusion, a key indicator of behavioural intentions towards stigmatised groups, and may be perceived as incapable of making decisions about finances and treatment.14

Experiences in health-care systems that reinforce the moral binary between “good” and “bad” opioid consumption, and “good” and “bad” people who use opioids, can perpetuate stigma among subpopulations of opioid users. For example, chronic non-cancer pain patients report prejudice towards people who are dependent on opioids or use them illicitly.15,16 A key way in which patients with chronic pain distance themselves from an “addict” identity is through stigmatising discourse that distinguishes between the “responsible” patient who takes medication for legitimate reasons and those who “chose” to use opioids for pleasure.16

It is important to note that the stigma associated with opioid use disorder does not exist in isolation, but intersects with and is compounded by marginalisation linked to race, gender, ethnicity, socioeconomic status, sexual orientation, and age.17,18 This is of particular importance in relation to the opioid crisis, which has disproportionally affected communities facing high levels of poverty, income inequality, and lack of access to social capital.19 Stigma also creates barriers for people with opioid use disorder in the criminal justice system, with widespread misconceptions regarding the purpose and benefits of treatment leading to programmes that are often unavailable or poorly implemented.20,21 Furthermore, the intersection of stigma associated with criminality and substance use can have detrimental impacts on patient self-efficacy and treatment engagement.18 There is also some evidence that people with mental health problems who use substances experience differing levels of stigma,17 although further research is needed to understand the relationships between specific mental health disorders and opioid or other drug-related stigma.

Although the intersectional nature of opioid-related stigma remains somewhat under-researched, one study identified 8 different forms of stigma among older adult patients receiving methadone, with those reporting greater stigma identifying more barriers to treatment.22 Evidence from the broader health literature has highlighted the importance of considering the co-experience of multiple stigmatised identities, as interventions that deal solely with a single health-related stigma are unlikely to have success in reducing social inequality and sustaining improvements in health.23 It is therefore critical that we understand the drivers of stigma and how it affects opioid use disorder treatment and policy. The aim of this narrative review is to discuss how opioid-related stigma impacts treatment provision and harm reduction, and provide strategies to reduce stigma at a social and structural level.

Sources of Opioid-Related Stigma

Stigma is defined by the World Health Organization as ‘a mark of shame, disgrace, or disapproval that results in an individual being rejected, discriminated against, and excluded from participating in a number of different areas of society’.24 Stigma is a social phenomenon that serves to devalue groups on the basis of particular characteristics,25 and comprises three main components arising from problems in knowledge (ignorance/misinformation), attitudes (prejudice), and behaviour (discrimination). These components are interrelated, where a lack of knowledge can result in negative attitudes and prejudice, which then leads to discriminatory behaviour.26

Stigma is frequently described as encompassing three interacting types: structural, public and internalised stigma. Structural stigma, also known as institutional stigma, exists at the systems or macro level and is enacted through rules, policies, and practices that constrain the opportunities and resources of the stigmatised group. Public stigma refers to stereotypes and negative attitudes that result in prejudice and discrimination. Self-stigma refers to negative thoughts and feelings that arise from identification with a stigmatised group, and has negative impacts on mental health and wellbeing as well as behaviour (eg, through avoiding treatment, or close contact with others).27

Each of these dimensions of stigma serve to reinforce each other, with stigma arising at the inter- and intrapersonal levels whilst being enacted through laws, policies, and regulation.28 In this sense, stigma goes beyond those who are stigmatised and is echoed outward through the broader community and inwards through the policies and procedures that guide treatment, including through the staff providing care at health services.29 In order to encapsulate these varying types of stigma, Pescosolido et al developed the Framework for Integrating Normative Influences on Stigma (FINIS) which theorises that there are various levels of social life which create normative expectations resulting in the process of stigmatisation.30 Using this framework, we have identified sources of opioid-related stigma at the macro (structural stigma), meso (public stigma) and micro (internalised stigma) levels, with a focus on how these impact opioid use disorder treatment (Figure 1). Following this, we highlight potential strategies and approaches to reduce stigma.

Macro Level

The underfunding of treatment for opioid use disorder is an important driver of structural stigma, as inequitable allocation of resources means that people face greater barriers to accessing appropriate care for substance use disorders than they do for other health needs.31 In addition to exacerbating health inequities, this has the effect of implicitly classifying people seeking treatment as less worthy or undeserving of care.28 More broadly, the systemic separation of substance use treatment services from physical and mental health services creates a number of challenges for people with substance use disorders. Institutional policies and funding arrangements that result in a lack of coordination between services reinforce stigma by fragmenting care, while simultaneously producing poorer health outcomes.8,28 For example, hospitals are an important component of the continuum of care for opioid use disorder; however, inadequate funding for addiction medicine specialists (who play a key role in referral and linkage to ongoing care)32 means structural stigma remains a significant barrier to addressing under-treatment within the acute care system.33

Structural stigma is enacted through laws, regulations, and policies that create barriers to accessing evidence-based treatments.31 Jurisdiction-based restrictions are often cited as barriers to prescribing opioid agonist therapy (OAT), including methadone and buprenorphine, even though OAT is supported by strong evidence demonstrating its effectiveness in reducing opioid-related harms and mortality.34 In certain high-income countries such as Australia, a significant cohort of people access OAT (in 2020 almost 50,000 clients received pharmacotherapies at over 3000 dosing points).35 However, in places with high rates of opioid mortality such as the United States (US), the availability of treatment programs including OAT have been slow to expand.36 The complex and restrictive regulatory framework surrounding these medications (and in particular, strict regulations governing methadone) is thought to be a key factor underlying the treatment gap in the US.37

The stigma associated with OAT is reinforced by restrictive treatment policies that require patients to attend specialised prescribing clinics and comply with strict treatment regimens. For example, OAT programs in Australia typically involve patients being administered daily doses under the supervision of a pharmacist or clinician, with patients eligible to receive “takeaway” doses following a period of treatment stability (eg, low number of missed doses; no evidence of diversion of doses to others). These types of programs have been associated with high levels of stigma, as the treatment policies and systems underpinning them frame only certain clients as trustworthy to manage takeaway doses, and patients often have to line up at pharmacies/clinics which potentially publicly identifies them as being treated for opioid use disorder.38–40 In addition, although treatment at community pharmacies can normalise provision of care for opioid use disorder, some pharmacies physically separate OAT clients from other customers, which can label them as “other”, or even at risk or dangerous.40 In particular, strict, long-term methadone programs have been referred to as constricting clients’ lifestyles through the “liquid handcuff” metaphor.41

Efforts to expand the availability of treatment options are also frequently hampered by regulatory barriers, limited funding, and a lack of governmental and organisational support. This can be seen in the opposition to injectable agonist treatment programs that provide pharmaceutically produced diacetylmorphine or hydromorphone to people who have not responded to first-line treatments. While these programs have been part of standard care in a number of European countries for two decades42 and are considered effective treatments for a particularly vulnerable subpopulation,43 the first trial of injectable hydromorphone in North America faced significant challenges due largely to the stigma associated with intravenous opioid use.44 Specifically, political concerns and a lack of available funding led to all US sites in the trial being abandoned, while misconceptions about the nature and purpose of treatment and fears regarding ‘honeypot effects’ (ie, drawing people with heroin use disorder from other areas and increasing crime and public disorder) limited recruitment efforts and constrained the implementation of the trial in Canada.44,45

Regulatory responses to increasing opioid-related mortality in recent years may have increased stigma towards people who use prescription opioids. Patients with chronic non-cancer pain report experiencing discrimination in health-care settings and increased barriers to treatment since the onset of the opioid epidemic and the implementation of restrictions to limit opioid prescribing.15,46 Prescription drug monitoring programs have also been associated with various unintended consequences, with a recent systematic review identifying stigmatising clinical responses (including treatment refusal and discontinuation) in 19 of the 41 studies included.47

Stigma can restrict consumer involvement in policy and program development.31 Many health services require police checks as a part of employment processes, meaning those who have a criminal history due to their substance use are precluded from participating in service planning and delivery. The credibility of consumers and their capacity to share knowledge can also be undermined when they are viewed with suspicion and disregard, or with limited ability to make decisions as fully rational subjects.8,39,48 For example, in a study of experiences and perspectives of staff at a clinic providing heroin-assisted treatment, consumers were blocked from participating due to ethical concerns that they would be “under the influence” and therefore incapable of providing informed consent.48 In return, lack of consumer participation can contribute to the design of services that do not take into account structural barriers (eg, restrictive opening hours, fear of police intervention).49

Language can reinforce stigma at the macro level, and when written into policies can uphold discriminatory practices and legitimize unfair treatment within the health-care system.50 The media, which primarily frames opioid use disorder as a criminal justice issue rather than as a treatable health condition,13 is a powerful driver of stigma that reinforces negative stereotypes about people with substance use disorders.51 Analysis of US news media over a 15-year period found less than 5% of stories mentioned expanding substance use treatment (with even fewer mentioning expanding access to medication-assisted treatments), while over 60 discussed law enforcement as a solution to the opioid crisis.13

The way the underlying problem and causes of opioid use disorder are constructed within treatment settings can also influence how people experience stigma, care and recovery. The notion that addiction is a medical problem, or a “disease”, can be traced back centuries.52 Towards the mid-1990s, based on neuroimaging research, a number of prominent US research agencies framed alcohol and other drug addiction as a chronic, relapsing brain disease.53,54 The National Institute on Drug Abuse (NIDA) in the US, which funds more than 85% of global research on drug addiction,55 has been a vocal advocate of the brain disease model of addiction since then. Regardless of the accuracy of the neurobiological evidence supporting the brain disease model,56 concerns exist regarding its utility in promoting health-based solutions to addiction rather than punitive responses (eg, incarceration), and how it influences stigma experienced by people experiencing opioid use disorder.

Advocates of the brain disease model of addiction argue that it will reduce moral judgments of people with substance use disorders, provide more effective behavioural and medical interventions (eg, anti-craving medication, cognitive brain training, and brain stimulation), and foster more effective public health policies for prevention and treatment.53,57 However, critics have argued that viewing addiction as a brain disease may increase stigma and lead policymakers to focus on individual medical solutions to social problems.56,58 There has been some empirical research examining the association between biogenetic explanations and stigma towards people with substance use disorders.59 For instance, although more of the public sampled in the US between 1996 and 2006 embraced a neurobiological understanding of mental illness (including alcohol use disorder), a neurobiological conception was not related to a reduction in stigma towards people with mental illnesses.2 Further, some evidence suggests that biomedically oriented explanations of mental illness and addiction may increase perceptions of dangerousness and desire for social distance, as well as pessimism about the likelihood of recovery.60

The association between framing opioid use disorder as a disease of the brain and stigma remains critically unresearched given language can shape how the public thinks about treatment and recovery.61 There is evidence to suggest that a greater endorsement of disease model beliefs may be associated with more stigmatised attitudes and lesser support for harm reduction initiatives,62 however other research suggests that there may not be one single term that is optimal across all settings, with more biomedical terms (“chronically relapsing brain disease”) associated with lower levels of stigma and blame, and less medical terminology (“opioid problem”) associated with stronger beliefs in recovery.60 The terms used to describe opioid use disorder and treatment can influence public support for investment in therapeutic versus punitive responses to opioid use disorder,60,63 highlighting the importance of carefully considering how opioid use disorders are framed when presented to the general population, so as to avoid amplifying existing barriers to treatment.

Meso Level

Organizational norms in the treatment system influence social interactions between providers and patients and can increase prejudice and discrimination.30 Negative core beliefs about opioid use disorder and its treatment (eg, “difficult” patients; pessimism about recovery; OAT “replacing one drug for another”) may stereotype patients and frame them as manipulative, unmotivated, undeserving of services, and unlikely to achieve lasting recovery.61 Stigma from health-care providers can manifest as lower empathy and engagement, non-collaborative and paternalistic approaches, suboptimal or disrupted care, and exclusion from services.29,50,64

Research indicates that providers are often reluctant to prescribe OAT due to negative attitudes towards patients, a lack of understanding of opioid use disorder, and pessimism about the effectiveness of treatment.64–66 Some report believing that OAT is beyond their scope of practice and does not belong in primary care.65 Attitudes among primary care physicians may be more stigmatising than the general public, compounded by fear of attracting “bad” clientele and concerns that providing OAT will have a negative impact on their professional reputation.66 Regulatory barriers may have perpetuated negative attitudes and beliefs regarding OAT among prescribers, with the additional training requirements, approval processes, and administrative burden associated with OAT programs signifying that it is onerous and risky.67

Compounding these effects, if clients wish to attend mutual aid groups (eg, 12-step programs) in addition to formal care, they often have to conceal their engagement with OAT programs or risk being ostracised for not being “clean” or abstinent. In particular, methadone treatment may be more stigmatised than injecting drug use5 and perceived as “morally equivalent” to heroin among opioid-using peers and their social network.68 Stigma against methadone may be the most pervasive and prevalent type of opioid-related stigma, with broadly comparable beliefs regarding its legitimacy as a medical treatment also documented among prescribers and pharmacists.6 Unsurprisingly, in-group stigmatisation of OAT is a strong predictor of discontinuing treatment6.

Routine interactions in pharmacy settings have also been identified as a source of stigma and discrimination for OAT patients. Even among samples reporting a high level of satisfaction with treatment, there is evidence that a substantial proportion feel they are treated “differently” to other customers,69 and regularly experience subtle verbal and non-verbal negativities directed towards them by pharmacy staff.70 In addition, pharmacists may refuse to provide services like syringe sales to people who inject drugs on the basis of appearance, relying on judgements about their moral character rather than an assessment of medical need.5

Stigma can be a barrier to naloxone supply and expansion of naloxone programs, with the perceptions that the lives of people who use opioids are less valuable and that naloxone has less of a place in mainstream health.71 The narrow perception of who may benefit from naloxone supply, and the stigmatised views towards those who use drugs has been shown to be a barrier preventing naloxone supply for pharmacists.72 In turn, this means that it has not been available for others at risk populations including people prescribed opioids for pain.73 Stigma may also undermine public support for naloxone: where naloxone recipients are perceived as dangerous, there may be less support for programs.74

Stigma also has considerable influence on community support of other harm reduction efforts, including safe consumption facilities. For example, only 29% of US adults support legalizing safe consumption facilities,75 and believe they would allow illegal activity and encourage people to use drugs,76 with higher levels of stigma associated with lower support.75 Consistent with a history of treating drug use as a moral failing and a criminal justice issue rather than a health problem, support for “safe consumption sites” is lower than support for “overdose prevention sites” (with the former emphasising making an illegal activity safer for a highly stigmatised population).77 More broadly, stigma towards opioid use is associated with lower support for public health–oriented policies, including passing laws to protect people from criminal charges if they seek help for an overdose and increasing government spending to improve substance use treatment.78

Micro Level

Internalising or anticipating public stigma can have a profound impact on service utilisation and recovery.50 In particular, the institutionalised stigma and social control in OAT delivery can reinforce an “addict” identity and lead to treatment becoming a source of shame and disempowerment.40 When internalised, the experience of stigma can jeopardise recovery and reintegration with mainstream society, reinforce a low sense of entitlement to quality care, and leave people to leave treatment prematurely.8,68,79

The experience of stigma is associated with delays in seeking treatment, increased rates of treatment withdrawal, withholding information in an effort to avoid sub-standard care, as well as increased engagement in risky behaviour such as needle sharing.8 Fear of being stigmatised is also a key barrier for carrying naloxone,80 and can lead to injecting drug users distancing themselves from harm reduction services such as syringe exchanges.5,81 Stigma can also result in label avoidance, the process by which people are reluctant to be diagnosed or be seen seeking treatment for an opioid use disorder. As a result, some people (including patients with chronic pain) report reluctance to use opioid medication, and may not identify as having an opioid use disorder or conceal their use of opioid pharmacotherapy to avoid being stigmatised by friends and family.6,82,83

Strategies to Reduce Stigma

Little research exists on the effectiveness of interventions to reduce stigma at the structural or macro level,28 particularly in relation to opioid use. However, policy makers and organizational leaders are in a key position to reinforce destigmatising language when describing opioid use disorder and treatment,50,84 and evidence suggests that effective communication could increase public support for evidence-based substance use policies and harm reduction initiatives.78,84 Large-scale stigma reduction campaigns also have the potential to alter social and cultural conceptions of opioid use disorder, although these should be carefully considered and built on a robust evidence base to ensure that they do not unintentionally reinforce negative attitudes.2 Narratives that humanize the experiences of people with opioid use disorders, emphasise that substance use disorders are treatable, and highlight structural barriers to treatment (eg, inadequate insurance coverage, provider shortages, and lack of availability), may increase public support without leading to a corresponding increase in stigma.84,85

Organizations have a major role to play in involving people with lived experience in governance processes, service delivery, evaluation, and care planning. Consumer engagement is a key principle in the planning and delivery of health services, and is increasingly becoming a regulatory requirement in addition to an ethical obligation.86 Involving consumers at the systems level is a strategy used worldwide to promote person-centred health-care, and in regard to opioid use may reduce stigmatisation of service users.87 Ideally, consumer involvement should also include developing and reviewing policies with the aim of eliminating stigmatising language.60

Ultimately, reforming laws and policies that create barriers to accessing quality care is critical to address treatment inequities and health disparities among people with opioid use disorder.28,30 This includes addressing the institutional policies and systems that fragment care, and integrating substance use disorder treatment into mainstream health-care. Removing regulatory barriers to prescribing OAT, for example, may help normalise treatment within primary care and allow opioid disorder to be managed like other chronic conditions: in addition to improving access, this provides opportunities to manage comorbid mental and physical health problems that may otherwise be left unaddressed.88 In turn, this may have beneficial effects on stigma enacted at the meso level, as greater exposure to OAT among prescribers is a consistent predictor of more positive attitudes towards treatment.89 Similar findings have been reported among pharmacists, and may reflect improvements in knowledge and confidence in addition to a shift in attitudes as they begin witnessing patients’ improvements first-hand.89,90

Expanding hospital-based models of delivery, such as low-threshold buprenorphine treatment initiated in hospital emergency departments,91 may also help normalise OAT and reduce stigma experienced by people with opioid use disorder within these settings. Embedding addiction medicine specialist services in hospitals has been identified as a key strategy to address inadequate or inappropriate treatment during hospitalisation and improve patient outcomes.92 Specialists have a key role in building capacity in hospital settings, as well as integrating training and education to address negative attitudes and beliefs regarding hospital-based care for opioid use disorder.93 However, structural stigma embedded in funding models positions addiction medicine as of lesser importance than other medical specialities, despite recognition of its essential role in ensuring high-quality care and improved patient outcomes.92

Addressing regulatory barriers to providing methadone (particularly in the US, where it is only available via accredited opioid treatment programs),94,95 may be beneficial in addressing the considerable stigma associated with this medication. While studies examining clinician attitudes have typically identified general barriers providing OAT (eg, concerns about “difficult” patients) rather than barriers associated with specific medications (eg, sublingual buprenorphine versus naltrexone),96 methadone is subject to unique stigma6 that may be compounded by its strict regulation. Retaining and expanding regulatory changes implemented during the COVID-19 pandemic to aid continuity of care97,98 is increasingly been recognised an important step in developing innovative models of care to address the opioid crisis,98,99 and may also reduce the stigma associated with methadone if treatment is made more accessible.

At the same time, there is a clear opportunity to reorient prescriber education and practices to reduce stigma.100 This could be achieved by providing comprehensive training during medical school or residency. Structured education that focuses on opioid use disorder treatment and emphasises recovery, as well as programs that include contact with patients in one-on-one or small group settings, has been found to decrease stigma and increase confidence and interest in providing OAT in later practice.101–103

Much has been written about the need to address the restrictive and coercive elements of OAT delivery.39,40,68 The recent introduction of long-acting injectable depot buprenorphine may offer an alternate approach to how OAT treatment could be delivered. Depot buprenorphine delivers prolonged therapeutic doses of buprenorphine in weekly or monthly formulations, and has been shown to be safe and effective treatment for opioid use disorder.104,105 It may also overcome many issues associated with sublingual OAT, such as poor adherence, risk of diversion or non-medical use of takeaway doses.106 Recent qualitative research exploring Australian clients’ experiences of depot buprenorphine has indicated that depot buprenorphine afforded positive benefits for many participants, including opportunities to avoid stigma experienced at pharmacies/clinics by not having to dose daily. Furthermore, depot buprenorphine allowed clients time to engage in activities (eg, travel, work) by releasing participants from previous OAT treatment regimens which helped them to form a new, non-stigmatised identity and a feeling of “normality”. However, for some clients, moving to depot buprenorphine disrupted engagements with important social/practical supports available at pharmacies/clinics.107 More broadly, early research has indicated that depot buprenorphine is a viable treatment option in prison settings (with benefits including lower risk of diversion and potentially lowering harms associated with injecting drug use, ie, blood-borne virus risks).108 Going forward, how depot buprenorphine is experienced in different international contexts, including how it may reduce stigma experienced in care settings, remains an important area of research.

Specific intervention strategies are needed to address the stigma around naloxone, and barriers to broader naloxone supply for people who use opioids. Illicit substance use is highly stigmatised and enormous efforts are needed in this space, yet prescribed opioid use which has its own stigma attached warrants consideration.109 One strategy to start to remove barriers to naloxone supply is to use a universal approach to screening and offering naloxone, with “opt-out” methods proposed for naloxone supply (ie, offering naloxone whenever opioids are discussed, without targeting specific populations).110 As health-care providers exist within communities, broader population-based efforts to reduce the stigma associated with substance use may reduce barriers to naloxone supply. Indeed, for as long as naloxone provision remains connected to illicit substance use, and the stigma associated with that, it is likely that barriers will remain.

Addressing stigmatising attitudes towards safe consumption facilities has proven to be an ongoing challenge. Despite evidence supporting their effectiveness, stigmatised views of safe consumption facilities and the people that use them are common among key stakeholder groups (eg, police, politicians, local businesses, residents), including the perception that they encourage initiation of injecting drug use, discourage people from seeking treatment, and increase neighbourhood crime. However, research suggests that attitudes may be improved when there is a collaborative approach to implementation (ie, between government, health-care, community, and law enforcement), an emphasis on community consultation and potential local impacts, and when facilities are situated within a comprehensive response to substance use treatment.111,112

With regard to stigma at the micro level, there is evidence that contact-based interventions that individualise and humanise people who use drugs may help reduce social distance.100,113 Building on the larger evidence base on stigma reduction in relation to mental health and HIV, contact-based interventions involve facilitating direct interaction between people living with stigmatised conditions and medical professionals and/or the general public (eg, through workshop where people with lived experience describe their challenges and personal experiences with stigma and recovery to targeted audiences).114,115 Contact-based interventions can also be implemented using digital strategies, as demonstrated by the US-based “Life Unites Us” campaign.116 A key component of this is a public campaign featuring video testimonials from people with lived experience of opioid use disorder and their families, presented alongside educational messages addressing key drivers of stigma (eg, the effectiveness of treatment, misconceptions about opioid use disorder, negative stereotypes). Preliminary results point towards high levels of positive engagement among people with lived experience as well as the general public, and suggest the campaign has potential to improve public stigma, as well as reducing self-stigma by empowering those who tell their stories.116

However, the social processes that lead to the formation of “ingroups” and “outgroups” are a fundamental part of human interaction and identity formation, and the micro-level stigma that emerges from this is deeply embedded in social and cultural norms.30 In turn, these cannot be separated from the broader context in which they operate and the laws, regulations, and rules that segregate people with opioid and other substance use disorders from mainstream society.28


Opioid use disorder remains highly stigmatised, with specific regulations regarding opioid prescribing, treatment delivery structures, and organisational and social norms serving to reinforce stigma in the treatment system and broader society. As it is important to address the numerous disparities that risk isolating people and creating barriers to receiving high-quality care, efforts to address this should focus on stigma at multiple levels. However, given the numerous structural sources of opioid-related stigma, strategies that focus on micro or meso-level stigma (eg, personal contact or training) are unlikely to be sufficient if done in isolation.30 Rather, change at the level of policy and systems is needed to ensure that people with opioid use disorder are treated with the same dignity and respect as any other patient group.
