RESUMO

Background: Timely information about trends in psychoactive substance use could yield tailored interventions and reduce potential harms. However, conventional epidemiological tools might have limited capacity to detect trends emerging on a local level. Objectives: The aim of this study was to explore best practice in the identification of new drug trends at the local level. Methods: A total of 33 key informants from seven European municipalities/regions were interviewed to describe trends in substance use in their locality and to provide expert insights on how these were identified. Semi-structured interviews were analyzed with open coding method. Results: Four case studies that described local trends and responses were compiled: onset of problematic GHB use in the Dutch municipality of Breda (1); emerging retail shops selling new psychoactive substances (NPS) across the regions of Czech Republic (2) and in the Portuguese Agueda and Coimbra (3); and use of drugs with unknown content in the Italian region of Emilia Romagna, and its city Bologna (4). "Early identifiers" in the four case studies were organizations that work directly with people who use drugs (PWUD), emergency departments, and local police. Efficient methods of horizontal and vertical information sharing, sometimes facilitated by communication platforms, were in place, such that included early warning systems on local, national, and supra-local level. Local-level identification systems appeared as best suited to provide locally relevant information. Conclusions: Best practice in identifying emerging trends should involve all relevant "early identifiers", should consist of supra-local exchange platforms, integrate the qualities of local-level identification, and be facilitated by local-level coordinators.

RESUMO

BACKGROUND AND AIMS: Despite advances in our knowledge of effective services for people who use drugs over the last decades globally, coverage remains poor in most countries, while quality is often unknown. This paper aims to discuss the historical development of successful epidemiological indicators and to present a framework for extending them with additional indicators of coverage and quality of harm reduction services, for monitoring and evaluation at international, national or subnational levels. The ultimate aim is to improve these services in order to reduce health and social problems among people who use drugs, such as human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infection, crime and legal problems, overdose (death) and other morbidity and mortality. METHODS AND RESULTS: The framework was developed collaboratively using consensus methods involving nominal group meetings, review of existing quality standards, repeated email commenting rounds and qualitative analysis of opinions/experiences from a broad range of professionals/experts, including members of civil society and organisations representing people who use drugs. Twelve priority candidate indicators are proposed for opioid agonist therapy (OAT), needle and syringe programmes (NSP) and generic cross-cutting aspects of harm reduction (and potentially other drug) services. Under the specific OAT indicators, priority indicators included 'coverage', 'waiting list time', 'dosage' and 'availability in prisons'. For the specific NSP indicators, the priority indicators included 'coverage', 'number of needles/syringes distributed/collected', 'provision of other drug use paraphernalia' and 'availability in prisons'. Among the generic or cross-cutting indicators the priority indicators were 'infectious diseases counselling and care', 'take away naloxone', 'information on safe use/sex' and 'condoms'. We discuss conditions for the successful development of the suggested indicators and constraints (e.g. funding, ideology). We propose conducting a pilot study to test the feasibility and applicability of the proposed indicators before their scaling up and routine implementation, to evaluate their effectiveness in comparing service coverage and quality across countries. CONCLUSIONS: The establishment of an improved set of validated and internationally agreed upon best practice indicators for monitoring harm reduction service will provide a structural basis for public health and epidemiological studies and support evidence and human rights-based health policies, services and interventions.

RESUMO

Recently, there is a global growing concern over the new (mainly synthetic) psychoactive substances, known as legal highs, research chemicals or bath salts. They are represented by various chemical groups imitating "old" illicit drugs with stimulant, euphoric, hallucinogenic or sedative effects. In the Czech Republic, the peak of their use and supply was observed at the beginning of 2011, when new psychoactive substances were available in smart shops known locally as Amsterdam shops - in that time mainly synthetic cathinones and also synthetic cannabinoids were present. After legislative change that placed tens of new substances under the control of criminal law in April 2011, new psychoactive substances are available at Internet and their use is (after short and media driven boom in early 2011) rather limited and decreasing. Though, the use of new synthetic stimulants was recently reported locally among problem (injecting) drug users; new very potent synthetic opioids represent potential threat of further expansion in this users subgroup.

RESUMO

There is ongoing debate about what policy approaches to cannabis use might best address health and social related harm. Profit-driven, adult-use cannabis markets have been introduced in the United States and Canada, where legalization reform has had mixed effects to date in terms of public health and has made limited progress in achieving social justice aims. Meanwhile, several jurisdictions have seen an organic evolution of alternative cannabis-supply regimes. Cannabis social clubs (CSCs), the focus of this commentary, are nonprofit cooperatives that supply cannabis to consumers with the goal of harm reduction. The peer and participatory aspects of CSCs may have positive effects on health-related outcomes of cannabis use, such as through encouraging the use of safer products and responsible use practices. The nonprofit objectives of CSCs may diminish the risk for increasing cannabis consumption in wider society. CSCs have recently made an important transition from grassroots organizations in Spain and elsewhere. In particular, they have become key players in top-down cannabis legalization reform in Uruguay and, most recently, Malta. The history of CSCs in reducing harm from cannabis use is an important advantage, but there might be concerns around the grassroots origins, low taxation opportunities, and capacity to sustain social objectives. Also, the CSC model might not seem unique, as contemporary cannabis entrepreneurs have absorbed some features of their community-based predecessors. CSCs can play an important role in future cannabis legalization reform due to their unique strengths as cannabis-consumption sites and can be effective in advancing social justice by giving people affected by cannabis prohibition agency and direct access to resources.

RESUMO

Developments in information technology have impacted on all areas of modern life and in particular facilitated the growth of globalisation in commerce and communication. Within the drugs area this means that both drugs discourse and drug markets have become increasingly digitally enabled. In response to this, new methods are being developed that attempt to research and monitor the digital environment. In this commentary we present three case studies of innovative approaches and related challenges to software-automated data mining of the digital environment: (i) an e-shop finder to detect e-shops offering new psychoactive substances, (ii) scraping of forum data from online discussion boards, (iii) automated sentiment analysis of discussions in online discussion boards. We conclude that the work presented brings opportunities in terms of leveraging data for developing a more timely and granular understanding of the various aspects of drug-use phenomena in the digital environment. In particular, combining the number of e-shops, discussion posts, and sentiments regarding particular substances could be used for ad hoc risk assessments as well as longitudinal drug monitoring and indicate "online popularity". The main challenges of digital data mining involve data representativity and ethical considerations.

RESUMO

BACKGROUND AND OBJECTIVES: In Lithuania, injecting heroin and other illicit opioids has dominated high-risk drug use since about 2000. More recently, patients have reported a high-risk use of amphetamines. Newly diagnosed HIV cases among people who inject drugs peaked in 2002 and 2009 and drug-related deaths have been on the increase. Yet research has reported a limited number of available harm-reduction programs. This study aimed to estimate the size of high-risk drug using populations in Lithuania and to apply these estimates in assessing the coverage of opioid substitution treatment (OST) and needle and syringe programs (NSP). METHODS: We used indirect prevalence estimation methods (HIV and Mortality Multiplier, Capture-Recapture, Truncated Poisson and the Multivariate Indicator Method) to obtain annual prevalence estimates of the population of high-risk opioid users (HROU) and of people who inject drugs (PWID) in Lithuania in 2015/2016. We computed the coverage of OST (the annual percentage of HROU in these programs) and NSP (the number of provided syringes per PWID per year), using the prevalence estimates and the data from drug services. RESULTS: There were between 4854 and 12,444 HROU and between 8371 and 10,474 PWID in Lithuania in 2015/2016. In addition, we obtained a preliminary estimate of 4742-7000 high-risk amphetamine users. This constitutes around 2.5-6.5 HROU and 4.4-5.3 PWID per 1000 inhabitants aged 15-64. On average, 9.9-25.5% of HROUs were in OST and an average PWID in Lithuania obtained 19-29 syringes via NSPs during the study period. CONCLUSIONS: While the current prevalence of high-risk drug use in Lithuania is comparable to other European countries and for PWID, it is above the average; and the coverage of OST and NSP services in this population is markedly lower than in most countries of the European Union and warrants further investment.

RESUMO

BACKGROUND AND AIMS: Not all people experiencing opioid dependence benefit from oral opioid agonist treatment. The aim of this study was to examine perceptions of (supervised) injectable opioid agonist treatment (iOAT) (described as 'an opioid similar to heroin self-injected at a clinic several times a day') among people who regularly use opioids and determine how common iOAT eligibility criteria accord with interest in iOAT. DESIGN: Cross-sectional survey SETTING: Sydney, Melbourne and Hobart, Australia PARTICIPANTS: A total of 344 people (63% male) who use opioids regularly and had ever injected opioids, interviewed December 2017-March 2018. The mean age of participants was 41.5 years [standard deviation (SD) = 8.5]. MEASUREMENTS: Primary outcome measures were interest in iOAT, factors associated with interest and the proportion of participants who would be eligible using common criteria from trials and guidelines. We examined willingness to travel for iOAT, medication preferences and perspectives on whom should receive iOAT. FINDINGS: Overall, 53% of participants (n = 182) believed that iOAT would be a good treatment option for them. Participants who believed that iOAT was a good treatment option for them were more likely to be male [adjusted odds ratio (aOR) = 1.76, 95% confidence interval (CI) = 1.10-2.82], have used heroin in the past month (aOR = 6.03, 95% CI = 2.86-12.71), currently regularly inject opioids (aOR = 1.84, 95% CI = 1.16-2.91) and have met ICD-10 criteria for opioid dependence (aOR = 3.46, 95% CI = 1.65-7.24). Those interested in iOAT had commenced more treatment episodes (aOR =1.06, 95% CI = 1.00-1.12). Among those interested in iOAT (n = 182), 26% (n = 48) met common eligibility criteria for iOAT. CONCLUSIONS: Interest in injectable opioid agonist treatment does not appear to be universal among people who regularly use opioids. Among study participants who expressed interest in injectable opioid agonist treatment, most did not meet common eligibility criteria.

RESUMO

INTRODUCTION AND AIMS: New psychoactive substances (NPS) represent hundreds of novel compounds. However, the general public might not be familiar with the overarching term NPS. This can result in both under- and over-reporting of NPS use. DESIGN AND METHODS: The study analysed the last-year prevalence of NPS use in an online survey conducted across I-TREND project countries (the Czech Republic, the Netherlands and Poland). Self-reported NPS use was assessed within two types of questions-a generic and a checklist question. We analysed prevalence for each question separately, incorporated the free-text probe 'other' that followed them, and combined the two questions into a conservative and an inclusive estimate. RESULTS: Including free-text responses to the 'other' categories increased prevalence of NPS use (from 51% to 56% for the checklist question and 25% to 32% for the generic question). Taking an inclusive approach to estimating prevalence (i.e. indicating NPS use in either a generic list or from the checklist) yielded a higher prevalence estimate (60%, 95% confidence interval 58-62%), compared to a more conservative approach in which NPS use had to be affirmed by both questions (27%, 95% confidence interval 26-29%). DISCUSSION AND CONCLUSIONS: Generic questions might lead to notably lower estimates of self-reported NPS use in comparison to checklists. However, creating relevant checklists is challenging and lengthy survey instruments have limitations. Further surveys might benefit from featuring a combination of the strategies used in this study-a single (generic) question involving a number of locally specific NPSs and a free-text 'other' probe.

RESUMO

Providing information about substances injected can reduce the negative impact of illicit drug consumption and support people who inject drugs to make informed decisions. In Australia, information about drugs injected relies largely on periodic self-report surveys. For the first time, the analysis of the residual content of used injecting equipment was conducted in a supervised injecting facility (SIF) located in Sydney, Australia. The aim was to gain a better understanding of the substances injected by clients through: (1) chemical analyses of the content of used syringes; (2) comparison of these results with clients' self-reported drug use; and (3) assessing the usefulness of analysing other injecting equipment to detect substances used. During one week in February 2019, syringes and other injecting equipment were collected at the Sydney SIF. Their residual content was analysed by gas-chromatography/mass-spectrometry. Heroin was the most commonly detected substance (present in 51% of syringes), followed by methamphetamine (22%) and oxycodone (10%). In addition to the main psychoactive substance, cutting agents reported in the literature were also detected in used syringes. The main psychoactive substance identified by laboratory analysis reliably corresponded with users' self-reported drug type. Analytical confirmation of substances injected allows for the provision of better targeted harm reduction messaging based on timely and objective data. The approach used is amenable to clients and feasible in the Australian SIF context. Upscaling and wider implementation could be done through Needle and Syringe Programs, and would support the early detection of harmful substances entering drug markets and better inform harm reduction strategies.

RESUMO

In the 1990s, a trial of prescribing pharmaceutical heroin for people with opioid-dependence had support from Australian State Health Ministers. However, in 1997 the proposal was vetoed by the federal Prime Minister in face of a negative tabloid media campaign. The debate then shifted to abstinence-orientated treatments. Later on, reduced heroin availability took opioid-related harms away from public sight. In this commentary, we aimed to explore the current need and the options to implement such program, lately referred to as supervised injectable opioid treatment (SIOT), in Australia. We argue that with the aging populations of opioid-dependent people who have not benefited from existing treatment options, increased misuse of prescription opioids, rising overdose rates, and the risk of unfolding overdose crisis, it seems timely to pilot SIOT here. Since the 1990s, seven RCTs as summarised in two systematic literature reviews, demonstrated that SIOT is effective for treatment-resistant opioid dependence. A sustainable SIOT model should, however, respond to key concerns related to its delivery, such as the lack of a patient exit strategy and the high cost of indefinite treatment. Evidence from long-term studies seem to support the notion that SIOT could be provided as a medium duration treatment (as opposed to short-term or indefinite), with the clear aim to stabilise patients, gradually wean them off injectable medication and transfer to opioid assisted treatment (OAT). Also, SIOT could be integrated into the existing public OAT clinics in Australia. This would reduce costs, but also provide a more patient-centred response to opioid dependence and further improve the acceptability and efficiency of OAT. The controversy that developed in the past should be mitigated by advances in research since the first Australian enquiry, use of a registered medication (open-label hydromorphone) rather than pharmaceutical heroin, and setting up clear treatment aims.

RESUMO

BACKGROUND: Cannabis policies should be relevant to communities most impacted by them. Home cultivation policies can engage people who grow cannabis and build on their motivation to supply a safe product. This paper aims to examine the laws pertaining to "home" (i.e. personal, small-scale) cannabis cultivation internationally and their different aspects, and to discuss the potential of these policies to be expanded into community-level cannabis supply models. METHODS: We reviewed relevant laws and regulations in states/countries that legalised, decriminalised or applied other non-prohibitive approaches to home cannabis cultivation. FINDINGS: Non-prohibitive approaches to home cannabis cultivation have been adopted in at least 27 jurisdictions. Twelve jurisdictions "de jure" legalised home cultivation (three U.S. states and Antigua and Barbuda legalised only home cultivation; six U.S. states, Uruguay and Canada legalised commercial sales as well). Eight states/countries "de facto" (Belgium, the Netherlands) or "de jure" decriminalised it (Czech Republic, Spain, Jamaica, and three Australian states). "De jure" depenalisation was in place in Chile and Brazil and recent court rulings yielded "de facto" depenalisation or "de facto" legalisation in five other jurisdictions (South Africa, Mexico, Colombia, Costa Rica and Georgia). Varying number of plants (per person and per property) and the circumstances of cultivation were in place. The key limitations of the regulations included (i) possession thresholds for the produce from home cultivations, (ii) rules about sharing the produce, and (iii) potentially disproportionate sanctions for non-authorised behaviours. Despite currently being limited, home cultivation policies might have the capacity to engage cannabis networks that already exist in the community and like that, enhance their participation in legitimate policy schemes. CONCLUSIONS: Rules around pooled cultivation and sharing could be made fit for purpose to accommodate community supply of cannabis. Home cultivation policies could serve as a basis for community-level cannabis supply models and as such, for more inclusive cannabis policies.

RESUMO

Health and social issues in aging populations of people who inject drugs (PWID) tend to aggregate, despite risky injecting practices decreasing with age. Identifying needs and avenues of support is becoming increasingly important. We described the health and social situation among clients of a long-running supervised injecting facility (SIF) in Sydney, Australia. An interviewer-administered survey (n = 182) assessed current housing status, employment, physical and mental health, incarceration history, drug use, engagement in drug treatment, health service utilization, and willingness to accept support. Results were compared to the information provided at initial visit. Up to half of the participants transitioned between lower- and higher-risk health and social indicators over time. Willingness to accept support was greatest amongst those with higher self-perceived need. Support for mental health was a low priority, despite the high self-reporting of mental health issues. SIF clients are open to support for health and social issues, despite ongoing active drug use. Lower-threshold services such as SIFs are well-positioned to recognize and respond to deteriorating health and social issues for PWID. Facilitating care and treatment remains a challenge when the services to which people are being referred are higher-threshold with a more rigid approach.

RESUMO

ISSUES: Drug consumptions rooms (DCR) and supervised injecting facilities (SIF) are expanding internationally. Previous reviews have not systematically addressed evaluation methodologies. APPROACH: Results from systematic searches of scientific databases in English until June 2017 were coded for paper type, country and year of publication. For evaluation papers, study outcome, methodology/study design and main indicators of DCR/SIF 'exposure' were recorded. KEY FINDINGS: Two hundred and nineteen eligible peer-reviewed papers were published since 1999: the majority from Canada (n = 117 papers), Europe (n = 36) and Australia (n = 32). Fifty-six papers reported evaluation outcomes. Ecological study designs (n = 10) were used to assess the impact on overdose, public nuisance and crime; modelling techniques (n = 6) estimated impact on blood-borne diseases, overdose deaths and costs. Papers using individual-level data included four prospective cohorts (n = 28), cross-sectional surveys (n = 7) and service records (n = 5). Individual-level data were used to assess safer injecting practice, uptake into health and social services and all the other above outcomes except for impact on crime and costs. Four different indicators of DCR/SIF attendance were used to measure service 'exposure'. IMPLICATIONS: Research around DCRs/SIFs has used ecological, modelling, cross-sectional and cohort study designs. Further research could involve systematic inclusion of a control group of people who are eligible but do not access SIFs, validation of self-reported proportion of injections at SIFs or a stepped-wedge or a cluster trial comparing localities. CONCLUSIONS: Methodologies appropriate for DCR/SIF evaluation have been established and can be readily replicated from the existing literature. Research on operational aspects, implementation and transferability is also warranted.

RESUMO

BACKGROUND: There is growing experience with the not-for-profit, consumer-driven cannabis social club (CSC) model that builds on self-supply, self-organization and harm-reduction; these are principles upon which people who use drugs (PWUD) have been engaging for decades. Recent legalization of cannabis in a number of jurisdictions and the related challenges in regulating production, sale, taxation and health-related matters have raised interest in non-commercial models of cannabis supply. The "codes of conduct" (CsoC) of CSC federations in Spain might reveal whether a consumer-based model could overcome these challenges. METHODS: To examine the content of the CSC auto-regulatory documents, an online search using key terms to identify the CsoC was conducted. Six documents were found; analysis of the main thematic categories and overarching themes was conducted. It was discussed how these corresponded to the areas of cannabis policy regulation and what the main limitations of the CSC model were. RESULTS: The CsoC detailed the rules for CSC administration, not-for-profit aims, "invitation only" and other conditions of membership, collective cultivation and security as well as for operation of the consumption venue and health-related initiatives. The themes in the CsoC overlapped with cannabis regulatory areas as outlined internationally. Concern over cannabis prices and potency was missing in the CsoC. The potential strengths of the CSC model might include safe environment for peer-delivered harm reduction practice, preventing illicit transactions, quality control, shifting economic surplus to the consumers and increased consumer responsibility. The limitations of the CSC model include high threshold, disguised motives, tax revenue and the risk of both under- and over-regulation. CONCLUSION: CSCs represent an opportunity to enhance consumer agency and responsibility. The right "to be self-supplied" with psychoactive substances can be granted to consumer associations - but authorities need to provide a framework to facilitate this voluntary self-organization, including minimum standards around public health and safety, and to involve consumers in the development of these regulations.

RESUMO

Since the 1990s, there have been seven clinical trials, and considerable clinical experience, in supervised injectable opioid treatment (SIOT) for individuals who, despite previous treatments, continue to inject illicit heroin and experience harmful health and social consequences. Most studies prescribed pharmaceutical heroin (diacetyl morphine, or DAM). This paper critically reviews randomised trials, long-term follow-up studies and qualitative reports of SIOT, and briefly reviews evidence regarding other medications used in injectable treatment as an alternative to DAM. It seeks to identify critical, unresolved issues regarding this treatment. Randomised trials comparing DAM with oral methadone (OM) report that while in treatment, participants randomised to DAM used less street heroin; reported spending less money on drugs, committed fewer crimes, and experienced improved health. Similar findings pertain to SIOT with hydromorphone. Because of the risks of overdose, diversion, and misuse, all recent trials of injected DAM involved supervised administration. This contributes to treatment being expensive to deliver. There is conflicting evidence regarding societal cost effectiveness, with some studies estimating that the reduction in crime more than compensates for the expense of the treatment. The critical, unresolved issues concerning this modality of treatment relate to the way in which it is approached-either as a medium-term, intensive intervention where other treatment has failed, designed to bring people into conventional opioid agonist treatment (OAT); or an indefinite support aimed at reducing social and personal harm. The former seems in line with the available findings on long-term effectiveness of SIOT and might be more acceptable given its rather moderate cost.

RESUMO

Objective The aim of the present study was to develop a framework for assessing regulatory options for medicinal cannabis in Australia. Methods International regulatory regimes for medicinal cannabis were reviewed with a qualitative policy analysis approach and key policy features were synthesised, leading to a conceptual framework that facilitates decision making across multiple dimensions. Results Two central organising dimensions of medicinal cannabis regulation were identified: cannabis supply and patient authorisation (including patient access). A number of the different supply options can be matched with a number of different patient authorisation options, leading to a matrix of possible regulatory regimes. Conclusions The regulatory options, as used internationally, involve different forms of cannabis (synthetic and plant-based pharmaceutical preparations or herbal cannabis) and the varying extent to which patient authorisation policies and procedures are stringently or more loosely defined. The optimal combination of supply and patient authorisation options in any jurisdiction that chooses to make medicinal cannabis accessible will depend on policy goals. What is known about the topic? Internationally, regulation of medicinal cannabis has developed idiosyncratically, depending on formulations that were made available and local context. There has been no attempt to date in the scientific literature to systematically document the variety of regulatory possibilities for medicinal cannabis. What does this paper add? This paper presents a new conceptual schema for considering options for the regulation of medicinal cannabis, across both supply and patient authorisation aspects. What are the implications for practitioners? The design of regulatory systems in Australia, whether for pharmaceutical or herbal products, is a vital issue for policy makers right now as federal and state and territory governments grapple with the complexities of medicinal cannabis regulation. The conceptual schema presented herein provides a tool for more systematic thinking about the options.

RESUMO

BACKGROUND: Prevalence of Hepatitis C Virus (HCV) among people who inject drugs (PWID) is high. Risky injecting behaviours have been found to decrease in drug consumption rooms (DCRs) and supervised injecting facilities (SIFs), yet HCV prevention and treatment in these settings have not been extensively explored. METHODS: To determine the range and scope of HCV prevention and treatment options in these services, we assessed DCR/SIF operational features, their clients' characteristics and the HCV-related services they provide. A comprehensive online survey was sent to the managers of the 91 DCRs/SIFs that were operating globally as of September 2016. A descriptive cross-country analysis of the main DCR/SIF characteristics was conducted and bivariate logistic models were used to assess factors associated with enhanced HCV service provision. RESULTS: Forty-nine valid responses were retrieved from DCRs/SIFs in all countries where they were established at the time of the survey (Australia, Canada, Denmark, France, Germany, Luxembourg, Netherlands, Norway, Spain and Switzerland). Internationally, the operational capacities of DCRs/SIFs varied in terms of funding, location, size and staffing, but their clients all shared common features of vulnerability and marginalisation. Estimated HCV prevalence rates were around 60%. Among a range of health and social services and referrals to other programs, most DCRs/SIFs provided HCV testing onsite (65%) and/or offered liver monitoring or disease management (54%). HCV treatment onsite was offered or was planned to be offered by 21% of DCRs/SIFs. HCV testing onsite was associated with provision of other services addressing blood-borne diseases and HCV treatment was linked to the provision of OST. HCV disease management was associated with employing a nurse at a DCR/SIF and HCV treatment was associated with employing a medical doctor. CONCLUSIONS: DCRs/SIFs offer easy-to-access HCV-related services for PWID. The availability of onsite medical professionals and provision of support and education to non-medical staff are key to enhanced provision of HCV-related services in DCRs/SIFs. Funding and support for HCV treatment at the community level, via low-threshold services such as DCRs/SIFs, are worthy of action.

RESUMO

BACKGROUND: It is now commonly accepted that there exists a form of drug supply, that involves the non-commercial supply of drugs to friends and acquaintances for little or no profit, which is qualitatively different from profit motivated 'drug dealing proper'. 'Social supply', as it has become known, has a strong conceptual footprint in the United Kingdom, shaped by empirical research, policy discussion and its accommodation in legal frameworks. Though scholarship has emerged in a number of contexts outside the UK, the extent to which social supply has developed as an internationally recognised concept in criminal justice contexts is still unclear. METHODS: Drawing on an established international social supply research network across eleven nations, this paper provides the first assessment of social supply as an internationally relevant concept. Data derives from individual and team research stemming from Australia, Belgium, Canada, Czech Republic, Finland, Germany, Hong Kong, the Netherlands, England and Wales, and the United States, supported by expert reflection on research evidence and analysis of sentencing and media reporting in each context. In situ social supply experts addressed a common set of questions regarding the nature of social supply for their particular context including: an overview of social supply research activity, reflection on the extent that differentiation is accommodated in drug supply sentencing frameworks; evaluating the extent to which social supply is recognised in legal discourse and in sentencing practices and more broadly by e.g. criminal justice professionals in the public sphere. A thematic analysis of these scripts was undertaken and emergent themes were developed. Whilst having an absence of local research, New Zealand is also included in the analysis as there exists a genuine discursive presence of social supply in the drug control and sentencing policy contexts in that country. RESULTS: Findings suggest that while social supply has been found to exist as a real and distinct behaviour, its acceptance and application in criminal justice systems ranges from explicit through to implicit. In the absence of dedicated guiding frameworks, strong use is made of discretion and mitigating circumstances in attempts to acknowledge supply differentiation. In some jurisdictions, there is no accommodation of social supply, and while aggravating factors can be applied to differentiate more serious offences, social suppliers remain subject to arbitrary deterrent sentencing apparatus. CONCLUSION: Due to the shifting sands of politics, mood, or geographical disparity, reliance on judicial discretion and the use of mitigating circumstances to implement commensurate sentences for social suppliers is no longer sufficient. Further research is required to strengthen the conceptual presence of social supply in policy and practice as a behaviour that extends beyond cannabis and is relevant to users of all drugs. Research informed guidelines and/or specific sentencing provisions for social suppliers would provide fewer possibilities for inconsistency and promote more proportionate outcomes for this fast-growing group.

RESUMO

BACKGROUND: Variations in drug laws, as well as variations in enforcement practice, exist across jurisdictions. This study explored the feasibility of categorising drug laws "on the books" in terms of their punitiveness, and the extent of their concordance with "laws in practice" in a cross-national comparison. METHODS: "Law on the books", classified with respect to both cannabis and other drug offences in the Czech Republic, NSW (AU) and Florida (USA) were analysed in order to establish an ordinal relationship between the three states. Indicators to assess the "laws in practice" covered both police (arrests) and court (sentencing) activity between 2002 and 2013. Parametric and non-parametric tests of equality of means, tests of stationarity and correlation analysis were used to examine the concordance between the ordinal categorisation of "laws on the books" and "laws in practice", as well as trends over time. RESULTS: The Czech Republic had the most lenient drug laws; Florida had the most punitive and NSW was in-between. Examining the indicators of "laws in practice", we found that the population adjusted number of individuals sentenced to prison ranked across the three states was concordant with categorisation of "laws on the books", but the average sentence length and percentage of court cases sentenced to prison were not. Also, the de jure decriminalisation of drug possession in the Czech Republic yielded a far greater share of administrative offenses than the de facto decriminalisation of cannabis use / possession in NSW. Finally, the mean value of most "laws in practice" indicators changed significantly over time although the "laws on the books" didn't change. CONCLUSIONS: While some indicators of "laws in practice" were concordant with the ordinal categorisation of drug laws, several indicators of "laws in practice" appeared to operate independently from the drug laws as stated. This has significant implications for drug policy analysis and means that research should not assume they are interchangeable and should consider each separately when designing research.

RESUMO

BACKGROUND: In September 2012, a series of methanol poisonings occurred in the Czech Republic as a result of an influx of illicit alcohol into (predominantly) cheap alcoholic beverages on the retail market. The public authorities decided to prevent public health risks by prohibiting sales of liquors that contained more than 20% alcohol (> 20% liquor). The "partial" prohibition lasted for almost two weeks, but the poisonings still continued. This article assesses the impact of the methanol poisoning risks and the (partial) prohibition on alcohol drinking patterns, and describes the understanding of risks and their mitigation in vulnerable groups. METHODS: The rapid assessment and response method (RAR) was used during the (partial) alcohol prohibition. Semi-structured interviews were conducted with respondents recruited for the study in alcohol-intake settings (e.g., bars and restaurants, street alcohol outlets) in six regions. In total, 107 alcohol users were interviewed, mostly with risky drinking patterns (69% scored ≥ 1 on the CAGE scale), and 53 alcohol retailers/staff members serving alcohol. RESULTS: About one third of the alcohol users in the study (35%) drank > 20% liquors during the prohibition; a higher score on the CAGE scale was associated with a lower probability of drinking > 20% liquors during the period of the prohibition, probably because of the perception of being at high risk of poisoning. There was some increase in drinking liquors with an alcohol content less than 20%. Those who continued drinking > 20% liquors typically did so in the belief that some sources of these were safe. CONCLUSIONS: Public policies aimed at reducing the risk of methanol poisonings in emergency situations should adopt broader measures than those focusing on market control. These measures include increased access to brief interventions, addressing the strategies that alcohol consumers adopt to prevent risk, and, in general, helping consumers make informed choices to prevent further fatalities.
