Introduction

British Columbia’s (BC) three-year drug decriminalization policy–introduced in January 2023 and amended just over a year later in 2024–had multiple goals, including reducing drug use stigma, shifting perceptions of drug use from a criminal to a health issue, and improving health outcomes for people who use drugs. As part of the policy, the BC government was required to implement public education tools to raise awareness and build understanding of the policy. However, little is known about the scope or impact of these public education efforts or how the information environment shaped public perceptions and attitudes toward the policy. To address these gaps, this study examines: 1) how BC’s decriminalization policy was communicated and represented across government and media sources, and 2) how exposure to these information sources influenced public support and perceptions of safety.

Methods

This mixed-methods study analyzed 98 government resources, 301 media articles, and a cross-sectional public opinion survey of 1200 BC residents. Content analyses of government resources and media articles examined government resource and media source intent, misinformation, misleading narratives, and perspectives, while the public opinion survey assessed information exposure, policy support, and perceived safety.

Results

Approximately one-quarter of all sources were government resources, and among those with publication dates, only 13 % were released prior to the policy’s implementation and 9 % contained misinformation, representing a missed opportunity for expectation-setting and public education. In contrast, 34 % of media articles contained misinformation, commonly misrepresenting the policy’s intent and linking decriminalization to increased crime, disorder, and public drug use. Survey findings showed no significant associations between specific information sources and outright opposition. However, respondents exposed to multiple information sources were significantly less likely to report a neutral stance compared to support (OR [95 % CI]: 0.31 [0.15–0.65]). Those accessing official/academic sources or multiple sources were also less likely to feel less safe (OR [95 % CI]: 0.22 [0.07–0.71] and 0.43 [0.24–0.78]).

Conclusion

These findings highlight critical gaps in government communication and the dominance of misrepresentative media framing in shaping public attitudes. Effective drug policy requires not only legislative change but also proactive, coordinated, and sustained public education strategies to counter misinformation, reduce stigma, and build lasting support.
导读:不列颠哥伦比亚省(BC)的三年毒品非刑事化政策于2023年1月出台,并在一年后的2024年进行了修订,该政策有多个目标,包括减少吸毒的耻辱,将吸毒的观念从犯罪转变为健康问题,以及改善吸毒者的健康状况。作为该政策的一部分,卑诗省政府被要求实施公共教育工具,以提高人们对该政策的认识和理解。然而,人们对这些公共教育努力的范围和影响知之甚少,也不知道信息环境如何塑造公众对政策的看法和态度。为了解决这些差距,本研究考察了:1)不列颠哥伦比亚省的非犯罪化政策如何在政府和媒体来源中传播和代表,以及2)这些信息来源的暴露如何影响公众的支持和对安全的看法。方法:这项混合方法研究分析了98个政府资源,301篇媒体文章,以及对公元前1200名居民的横断面民意调查。政府资源和媒体文章的内容分析检查了政府资源和媒体来源的意图、错误信息、误导性叙述和观点,而公众舆论调查评估了信息暴露、政策支持和感知安全。结果:大约四分之一的信息来源是政府资源,在那些有发布日期的信息来源中,只有13%是在政策实施之前发布的,9%包含错误信息,这意味着错过了设定期望和公众教育的机会。相比之下,34%的媒体文章包含错误信息,通常歪曲了政策的意图,并将非刑事化与犯罪增加、混乱和公共吸毒联系起来。调查结果显示,具体的信息来源和直接的反对意见之间没有明显的联系。然而,与支持相比,暴露于多种信息来源的受访者更不可能报告中立立场(OR [95% CI]: 0.31[0.15-0.65])。那些访问官方/学术来源或多个来源的人也不太可能感到不安全(or [95% CI]: 0.22[0.07-0.71]和0.43[0.24-0.78])。结论:这些发现突出了政府沟通的关键差距,以及塑造公众态度的虚假媒体框架的主导地位。有效的毒品政策不仅需要立法改革,还需要积极、协调和持续的公共教育战略,以打击错误信息,减少耻辱,并建立持久的支持。

Introduction

Complex polysubstance use is increasing in the United States. However, most epidemiological literature relies on traditional data sources, especially CDC WONDER, which is limited to employing two ICD-10 codes concurrently. We leverage complete medical examiner records from Los Angeles County to examine the limitations of CDC WONDER data for detecting polysubstance drug deaths.

Methods

Drug-involved deaths occurring in Los Angeles County were described using the CDC WONDER system and Los Angeles County Medical Examiner data. Annual single-drug involvement rates were compared between the two data sources. The average number of drugs, and the proportion of polysubstance deaths involving 3 or more substances was summarized by year. UpSet plot visualization was employed for complex set analysis.

Results

Overall concordance in single-substance death counts between CDC WONDER and medical examiner records was high among n = 6 substances assessed. The average number of drugs reported per death had a skewed distribution and increased from 1.72 in 2012 to 2.29 in 2023. The percentage of polysubstance deaths with 3+ drugs increased from 51% in 2012 to 74% in 2023. The number of unique polysubstance combinations with 3+ substances increased from 11 in 2012 to 57 in 2023.

Discussion

Although concordance is high for single-substance involvement rates, CDC WONDER fails to capture the majority of polysubstance deaths adequately, as about three-quarters of these deaths are incompletely described using its 2-drug limit. This limitation has worsened as deaths increasingly involve more drugs on average. We illustrate a huge variety of polysubstance combinations that can be seen in medical examiner deaths. As the overdose crisis grows increasingly polysubstance in nature, improving the epidemiological tracking of deaths involving multiple drugs, and drugs not captured by ICD-10 codes currently, is of paramount importance.
在美国,复合多物质的使用正在增加。然而,大多数流行病学文献依赖于传统的数据来源,特别是CDC WONDER,它仅限于同时使用两个ICD-10代码。我们利用洛杉矶县完整的法医记录来检验CDC WONDER数据在检测多物质药物死亡方面的局限性。方法:使用CDC WONDER系统和洛杉矶县法医数据描述洛杉矶县发生的与药物有关的死亡。比较两种数据来源的年度单一药物受累率。按年汇总药物的平均数量和涉及3种及3种以上药物的多物质死亡比例。复集分析采用颠覆图可视化。结果:在评估的n = 6种物质中,CDC WONDER单物质死亡计数与法医记录之间的总体一致性很高。每例死亡报告的平均药物数量分布不均匀,从2012年的1.72种增加到2023年的2.29种。使用3种以上药物的多物质死亡比例从2012年的51%增加到2023年的74%。具有3种以上物质的独特多物质组合从2012年的11种增加到2023年的57种。讨论:虽然单一药物介入率的一致性很高,但CDC WONDER未能充分捕获大多数多药物死亡,因为大约四分之三的这些死亡使用其2种药物限制不完整地描述。随着平均死亡人数越来越多地涉及更多的药物,这种限制变得更加严重。我们说明了在法医死亡中可以看到的各种各样的多物质组合。由于过量危机的性质越来越多,因此,改善对涉及多种药物以及目前未被《国际疾病分类-10》代码所涵盖的药物的死亡的流行病学追踪至关重要。

Introduction

Illicit drug-related harms remain a significant public health issue globally and in Australia, particularly among people who inject drugs (PWIDs) in prison settings where access to harm reduction (HR) is severely limited. This study aimed to explore the experiences of PWIDs incarcerated in Queensland prisons, focusing on how the prison environment shaped their risk of blood-borne viruses (BBVs) and injection-related bacterial infections (IRBIs), and to identify ways current HR interventions could be improved.

Methods

The study recruited 30 PWIDs aged 29–52 who had experienced incarceration in Queensland and overdosed within the past three years. Participants were recruited via social media and lived-experience organisations providing culturally safe support. Semi-structured interviews were audio-recorded, transcribed, and analysed using a critical realism framework and reflexive thematic analysis to identify and develop common themes.

Results

Participants described how structural, economic, and social factors within Queensland prisons foster risky injecting practices and elevate BBV and IRBI risks. Limited access to HR resources, punitive policies, and inadequate healthcare led to reliance on informal economies and unsafe behaviours such as equipment sharing and syringe cutting. Stigma and fear further hindered healthcare access. Participants emphasised the need for expanded HR measures, including needle and syringe programs, delivered within enabling environments that reduce barriers and promote peer support.

Discussion

These findings suggest more consideration regarding policy changes to enhance the accessibility of HR interventions, including needle and syringe programs in Queensland prisons.
在全球和澳大利亚,与非法毒品有关的危害仍然是一个重大的公共卫生问题,特别是在监狱环境中注射吸毒者中,因为在监狱环境中获得减少伤害服务的机会严重有限。本研究旨在探讨被关押在昆士兰州监狱的PWIDs的经历,重点关注监狱环境如何影响他们患血源性病毒(bbv)和注射相关细菌感染(IRBIs)的风险,并确定当前人力资源干预措施的改进方法。方法本研究招募了30名年龄在29-52岁之间的PWIDs,他们在过去三年内经历过昆士兰州的监禁和过量用药。参与者是通过社交媒体和提供文化安全支持的现场体验组织招募的。对半结构化访谈进行录音、转录,并使用批判现实主义框架和反身性主题分析进行分析,以确定和发展共同主题。结果参与者描述了昆士兰监狱内的结构、经济和社会因素如何助长危险的注射行为,并提高BBV和IRBI风险。获得人力资源的机会有限、惩罚性政策和不充分的医疗保健导致对非正规经济的依赖以及设备共享和注射器切割等不安全行为。耻辱感和恐惧进一步阻碍了获得医疗服务。与会者强调需要扩大人力资源措施,包括针头和注射器规划,在减少障碍和促进同伴支持的有利环境中提供。这些研究结果表明,需要更多地考虑政策变化,以提高人力资源干预措施的可及性,包括昆士兰监狱的针头和注射器项目。

Introduction

North America faces an ongoing overdose crisis driven by a volatile and toxic drug supply comprised primarily of fentanyl, fentanyl analogues and other adulterants. Safer opioid supply (SOS) programs prescribe pharmaceutical opioids to individuals at high risk of overdose mortality. This study evaluated changes in non-fatal overdose prevalence in the 6 months after SOS program initiation among SOS participants in Kitchener-Waterloo, Canada.

Methods

We analyzed data from a pre-post observational cohort of clients enrolled in a SOS program between July 2021 and October 2023. Baseline surveys were completed upon program entry, with follow-up surveys after 6 months. We compared non-fatal overdose prevalence between baseline and follow-up using McNemar’s test and calculated adjusted odds ratios (aOR) using generalized estimating equation (GEE) models, controlling for potential confounders including homelessness, hospitalization, daily fentanyl use, and incarceration.

Results

Among 100 participants completing follow-up (out of 162 who completed a baseline survey), overdose prevalence decreased significantly from 60 % (95 % Confidence Interval (CI): 50–69) at baseline to 15 % (95 % CI: 9–23) at follow-up (p < 0.001). Overdose incidence rates declined from 48.5 to 3.3 per 100 person-months. After adjusting for confounders, participants had 83 % lower odds of overdose during follow-up (aOR 0.17, 95 % CI: 0.08–0.38).

Discussion

Participants in a SOS program experienced significant reductions in non-fatal overdose during the 6 months following program initiation. SOS clients are a high-risk population with elevated overdose rates at baseline; these results support expanding safer supply programs as part of a comprehensive set of strategies to address the overdose crisis.
北美面临着由主要由芬太尼、芬太尼类似物和其他掺假物组成的挥发性和有毒药物供应所导致的持续过量危机。更安全的阿片类药物供应(SOS)计划向有过量死亡风险的个体开出药物阿片类药物。本研究评估了加拿大基奇纳-滑铁卢地区SOS参与者在SOS项目启动后6个月内非致命性药物过量发生率的变化。方法:我们分析了2021年7月至2023年10月期间参加SOS项目的患者的前后观察队列数据。基线调查在项目开始时完成,6个月后进行随访调查。我们使用McNemar试验比较了基线和随访期间的非致命性药物过量患病率,并使用广义估计方程(GEE)模型计算了调整后的优势比(aOR),控制了潜在的混杂因素,包括无家可归、住院、每日芬太尼使用和监禁。结果在100名完成随访的参与者中(162名完成基线调查的参与者中),药物过量患病率从基线时的60%(95%置信区间(CI): 50-69)显著下降到随访时的15% (95% CI: 9-23) (p < 0.001)。药物过量发生率从每100人月48.5下降到3.3。在调整混杂因素后,参与者在随访期间服用过量的几率降低了83% (aOR 0.17, 95% CI: 0.08-0.38)。SOS项目的参与者在项目启动后的6个月内经历了非致命性药物过量的显著减少。SOS客户是高危人群,基线时用药过量率升高;这些结果支持扩大更安全的供应计划,作为解决过量危机的综合战略的一部分。

Background

New Zealand’s (NZ) drug policy has largely retained a criminal justice focus for over 50 years, despite multiple reviews recommending legislative overhaul, and public support for a health-based approach. Deliberative democracy, including mechanisms such as citizens assemblies, have been identified as a potential mechanism to overcome some of the inertia within drug policy. This project aimed to 1) engage with a group of citizens to try to develop a group consensus on how best to respond to drugs in NZ, and 2) explore how community members’ diverse views were affected by deliberation, and their experiences of a deliberative workshop process.

Methods

Seven deliberative workshops were held with a group of ten retirees living in Christchurch NZ. Participants were asked to engage in group discussions that may (or may not) lead to a group consensus. Workshops included discussions with expert guest speakers, reading and discussion of journal articles and reports. The final session was a debrief, the purpose of which was to understand what influenced participants’ views, and the experience of the deliberative workshop process.

Results

The group produced a consensus statement and set of recommendations for politicians and policymakers, which emphasised a health-based approach to drugs. The value of dialogue, mutual learning, and deliberation to achieve change arose from analysis of the debrief.

Conclusions

This study highlights the potential value of deliberative democracy and demonstrates that a group of ‘lay’ citizens can reach nuanced, thoughtful, and practical solutions for drug policy.
背景50多年来,尽管多次审查建议进行立法改革,公众支持以健康为基础的做法,但新西兰的毒品政策在很大程度上仍以刑事司法为重点。协商民主,包括公民集会等机制,已被确定为克服毒品政策内某些惰性的潜在机制。该项目旨在1)与一群公民接触,试图就如何最好地应对新西兰的毒品问题达成群体共识;2)探索社区成员的不同观点如何受到审议的影响,以及他们在审议研讨会过程中的经历。方法对居住在新西兰基督城的10名退休人员进行了7次研讨。参与者被要求参与小组讨论,小组讨论可能(也可能不会)导致小组共识。讲习班包括与专家嘉宾进行讨论,阅读和讨论期刊文章和报告。最后一届会议是一次汇报,其目的是了解影响与会者意见的因素,以及审议讲习班进程的经验。该小组为政治家和决策者提出了一份共识声明和一套建议,强调以健康为基础的药物处理方法。对话、相互学习和深思熟虑以实现变革的价值来自对汇报的分析。这项研究突出了协商民主的潜在价值,并表明一群“外行”公民可以就毒品政策达成细致入微、深思熟虑和实用的解决方案。

Background

This study investigated the implementation of Denmark's partial decriminalization of possession of illicit drugs for personal use with its criteria of socioeconomically disadvantaged individuals dependent on drugs other than cannabis. The focus was on assessing trends in the frequency and proportion of cases settled with warnings as an alternative to criminal sanctions before and after legislative changes in 2004.

Methods

We graphed the frequency and proportion of warning decisions issued over time (2003–2020) for drug possession among cases classified as eligible or ineligible, with eligibility defined as the offender being both socioeconomically disadvantaged and dependent on drugs other than cannabis. Mixed effects logistic regression was used to examine the interaction between eligibility status and date of offense on the odds of receiving a warning instead of a fine and to examine additional offender- and case-related factors associated with receiving a warning among eligible cases after the 2004 legislative changes. Changepoint time series analyses were also carried out to identify important changes in sentencing trends over time. Data sources included the National Police of Denmark's case management system and national health, crime, population, and labor registers.

Results

The findings indicated that the proportion of eligible cases receiving warnings remained low throughout the study period, with fewer than 16 % of eligible cases settled with a warning, rather than a fine, in any given year. Interaction analysis showed that the policy resulted in relatively more lenient decisions for eligible cases compared with ineligible cases, although the overall use of warnings declined. Additionally, both offender-related factors (e.g., sex) and case-related factors (e.g., police district, type of drug) were associated with the odds of receiving a warning among eligible cases.

Conclusion

The study highlights persistent challenges in implementing the decriminalization policy, indicating the need for legislative clarity, consistent enforcement practices, and targeted education for law enforcement. Future research should monitor the impact of recent legislative amendments and explore strategies to address systemic barriers in drug policy reform.
背景:本研究调查了丹麦对持有供个人使用的非法药物部分非刑事化的执行情况,其标准是依赖大麻以外药物的社会经济上处于不利地位的个人。调查的重点是评估在2004年立法修订前后,以警告替代刑事制裁解决案件的频率和比例的趋势。方法:我们绘制了一段时间内(2003-2020年)对毒品持有的警告决定的频率和比例,这些案件被划分为合格或不合格,合格定义为犯罪者既处于社会经济不利地位,又依赖大麻以外的药物。使用混合效应逻辑回归来检查资格状态和犯罪日期之间的相互作用对收到警告而不是罚款的几率的影响,并检查2004年立法变更后合格案例中与收到警告相关的其他罪犯和案件相关因素。还进行了变化点时间序列分析,以确定量刑趋势随时间的重要变化。数据来源包括丹麦国家警察的案件管理系统和国家卫生、犯罪、人口和劳工登记。结果:研究结果表明,在整个研究期间,接受警告的合格案例的比例仍然很低,在任何一年,只有不到16%的合格案例以警告而不是罚款解决。相互作用分析表明,尽管警告的总体使用有所下降,但该政策对符合条件的案件的判决相对较宽松。此外,与罪犯有关的因素(例如,性别)和与案件有关的因素(例如,警察区,毒品类型)都与合格案件中收到警告的几率有关。结论:该研究强调了在实施非刑事化政策中持续存在的挑战,表明需要明确立法,一致的执法实践,并对执法人员进行有针对性的教育。未来的研究应监测最近立法修订的影响,并探索解决药物政策改革中的系统性障碍的策略。

In 2024, Germany became the most populous European country to legalize home cannabis cultivation. This study provides the first empirical evidence on both public support for and engagement in home cultivation in this new regulatory context. Using survey data from a representative online-panel (n = 1500), we conducted hierarchical regression analyses to examine the factors associated with attitudinal outcomes (support for legalization) and behavioral outcomes (self-reported cultivation in the past or present). Results show that sociodemographic associations with support and cultivation are largely explained by cannabis experience. Among these factors, age and consumption emerged as the most consistent correlates across models. Expectations regarding the consequences of legalization were strongly associated with support but showed little relation to actual cultivation behavior. People who have cultivated expressed substantially higher support and more favorable expectations than those who have not, although participants overall tended to evaluate legalization positively. The only consistently negative expectation shared across groups was that legalization may increase cannabis use in society. Overall, support for legalization appears to be influenced by a broad set of expectations about societal consequences, whereas cultivation behavior is more closely tied to individual experience and personal motivations. While the study is situated in the German context, its insights are relevant beyond national borders: as the largest EU member state to legalize home cultivation, Germany’s experience may provide valuable lessons for other jurisdictions considering similar reforms.
2024年,德国成为将家庭大麻种植合法化的欧洲人口最多的国家。本研究提供了在这种新的监管背景下公众对家庭种植的支持和参与的第一个经验证据。利用代表性在线小组(n = 1500)的调查数据,我们进行了分层回归分析,以检查与态度结果(支持合法化)和行为结果(过去或现在的自我报告培养)相关的因素。结果表明,支持和种植的社会人口学关联在很大程度上可以用大麻经验来解释。在这些因素中,年龄和消费是各模型中最一致的相关性。对大麻合法化后果的预期与支持密切相关,但与实际的大麻种植行为关系不大。尽管参与者总体上倾向于积极评价大麻合法化,但与没有大麻合法化的人相比,大麻合法化的人表达了更高的支持和更有利的期望。各群体唯一一致的负面预期是,大麻合法化可能会增加社会对大麻的使用。总体而言,对大麻合法化的支持似乎受到对社会后果的广泛预期的影响,而大麻种植行为则与个人经历和个人动机更密切相关。虽然这项研究是在德国的背景下进行的,但它的见解超越了国界:作为将家庭种植合法化的最大欧盟成员国,德国的经验可能为其他考虑类似改革的司法管辖区提供宝贵的经验教训。

Objective

To develop evidence-informed recommendations on the health effects of e-cigarettes to guide healthcare practitioners and the public to balance individual and population harm reduction.

Methods

Systematic and umbrella reviews investigating the health effects of e-cigarette use were conducted (September 2017 – January 2024). An international panel of subject matter experts (n = 23) and people in Canada with lived experience (n = 7) participated in a two-day, hybrid meeting, and used a consensus-based approach to develop recommendations. A guidance resource and four accompanying knowledge products were tested for usability with end users.

Results

Consensus was reached on 14 recommendations spanning four health effects: carcinogen exposure, cardiovascular health, respiratory health, and nicotine dependence. Quality of evidence was voted as ranging from high/moderate to moderate/low, and strength of most recommendations was voted as strong.

Conclusions

Guidance has been informed by best available evidence and expertise, providing direction to support decision-making. The use of established methods to evaluate divergent published literature combined with consensus-building methods among a range of stakeholders on vaping is possible. As higher quality evidence continues to emerge, recommendations will require iterative refinement.
目的:就电子烟对健康的影响提出循证建议,以指导医疗从业人员和公众平衡减少个人和群体危害。方法:从2017年9月至2024年1月,对电子烟使用对健康的影响进行了系统和全面的综述。一个由主题专家组成的国际小组(n = 23)和加拿大有实际经验的人(n = 7)参加了为期两天的混合会议,并采用基于共识的方法提出建议。对一个指导资源和四个附带的知识产品进行了最终用户可用性测试。结果:就14项建议达成共识,涉及4种健康影响:致癌物质暴露、心血管健康、呼吸系统健康和尼古丁依赖。证据质量从高/中等到中/低,大多数建议的强度被评为强。结论:可获得的最佳证据和专业知识为指导提供了信息,为支持决策提供了方向。使用既定的方法来评估不同的已发表文献,并结合在一系列利益相关者之间建立共识的方法,是可能的。随着更高质量的证据不断出现,建议将需要反复改进。

Introduction

Drug market related violence has plagued Sweden in the last decade and has geographically been linked to open drug scenes, ODSs. Surveys have been used to identify ODSs in local police districts in Stockholm County since 2017. The present study analyzes how ODSs and hot spots of police-reported crime relate to geographical indicators of systemic drug market violence.

Method

Drug hot spots are identified using clustering methods. Drug hot spots and ODSs are then both geographically matched with markers for organized crime to analyze the extent to which they can serve as geographical markers for systemic drug market related violence. The markers for organized crime employed are shootings and organized crime related activities described in court cases that include encrypted phone texts.

Results

Our findings suggest that drug hot spots are a rather weak predictor of systemic drug market related violence, whereas ODSs function reasonably well, particularly in the case of ODSs in areas with an established presence of criminal networks.

Conclusion

Measuring drug market locations is complex, but drug market related violence can be understood geographically by linking typical gang-related crimes to places with open drug scenes.
导言:在过去十年中,与毒品市场有关的暴力事件一直困扰着瑞典,并且在地理上与公开的毒品场景ods有关。自2017年以来,已使用调查来确定斯德哥尔摩县当地警区的ods。本研究分析了警方报告的犯罪热点与系统性毒品市场暴力的地理指标之间的关系。方法:采用聚类方法识别药物热点。然后,将毒品热点和滥用毒品地点在地理上与有组织犯罪的标记相匹配,以分析它们在多大程度上可以作为与毒品市场有关的系统性暴力的地理标记。使用有组织犯罪的标志是在法庭案件中描述的枪击和有组织犯罪相关活动,包括加密的电话短信。结果:我们的研究结果表明,毒品热点是系统性毒品市场相关暴力的一个相当弱的预测因素,而ODSs的功能相当好,特别是在已经建立犯罪网络的地区的ODSs。结论:毒品市场位置的测量是复杂的,但通过将典型的帮派犯罪与公开的毒品现场联系起来,可以从地理上理解毒品市场相关暴力。

Due to the increase in the use of illicit drugs in western Europe, key policy stakeholders and researchers have increasingly focused on the drugs–violence nexus. However, previous research on changing substance use patterns among homicide offenders, particularly studies that consider alcohol and drugs simultaneously, remains limited. Comparative analyses of youth- versus adult-perpetrated homicides from a substance use perspective are particularly scarce. The current study addressed the research gaps using a unique Finnish dataset of homicides committed between 2002 and 2022 and comparing substance use among young (15–29-year-olds; n = 589) and adult (30+-year-olds; n = 1249) offenders. The findings point to significant changes in substance use patterns in homicides during the study period, especially with respect to youth homicides. Driven largely by a considerable drop in alcohol-related homicides among both youth and adults, the findings are consistent with previous literature suggesting that illicit drugs may be becoming proportionally more central than older patterns of substance use in violence. Specifically, the findings indicate that the substance-use profile of youth-perpetrated homicides particularly has changed markedly over the study period: the dominant context has shifted from situational alcohol consumption to direct or indirect involvement with drugs, and most recently, drug-related homicide profiles accounted for over 40 % of youth-perpetrated homicides. Regarding substance co-use patterns, the findings show that while alcohol-related homicides most often do not involve the co-use of other substances, various drug categories are correlated among homicide offenders, and the co-use of multiple drugs is common among both young and adult drug-involved offenders.
由于西欧非法药物使用的增加,主要政策利益攸关方和研究人员越来越关注毒品与暴力的关系。然而,以前对杀人罪罪犯中不断变化的药物使用模式的研究,特别是同时考虑酒精和毒品的研究,仍然有限。从药物使用的角度对青少年和成人犯下的杀人案进行比较分析尤其稀少。目前的研究使用了2002年至2022年间芬兰独特的凶杀案数据集,并比较了年轻(15 - 29岁;n = 589)和成年(30岁以上;n = 1249)罪犯的药物使用情况,解决了研究空白。研究结果表明,在研究期间,杀人案中的药物使用模式发生了重大变化,特别是在青少年杀人案中。在很大程度上,由于青少年和成年人中与酒精有关的杀人案大幅下降,这一发现与以前的文献一致,表明非法药物可能在比例上比暴力中使用药物的旧模式更为重要。具体而言,研究结果表明,在研究期间,青少年凶杀案的物质使用情况发生了显著变化:主要情况已从情境性饮酒转变为直接或间接参与毒品,最近,与毒品有关的杀人情况占青少年凶杀案的40%以上。关于药物共同使用模式,研究结果表明,虽然与酒精有关的杀人案通常不涉及其他物质的共同使用,但杀人罪犯之间的各种药物类别是相关的,并且在青少年和成年毒品犯罪者中共同使用多种药物是常见的。
