Blair A, Siddiqi A. Social determinants of ethno-racial inequalities in substance use: a decomposition of national survey data. Soc Psychiatry Psychiatr Epidemiol 2022; 57:2013-2022.

Abstract
BACKGROUND Similar to the US, mortality due to suicide and the use of opioids, alcohol, and other substances (so-called "Deaths of Despair"), is rising in Canada and has been disproportionately observed among Whites compared to other racial and ethnic groups. This study aimed to assess the determinants of the ethno-racial differences in the use of substances that underlie these deaths. METHODS Using nationally representative data from the Canadian Community Health Survey (2003, 2015-2016, 2018 cycles), a decomposition analysis was performed to estimate the contribution of psychosocial determinants, including age, sex, marital status, immigration, education, income, rurality, and affective health on inequalities between White and non-White populations in illicit substance, opioid, and problematic alcohol use and combined use (≥ 2) of substances. RESULTS Overall, White respondents reported higher levels (by 5% to 10%) of substance use than non-White peers. Over 30% of the ethno-racial inequalities in illicit substance, problematic alcohol, and polysubstance use are explained by the protective role of immigration among those who are not White, whose low levels of substance use lower the prevalence in the non-White population overall. Among those born in Canada, no ethno-racial differences in substance use were observed. CONCLUSION Social determinants, particularly immigrant status, explain a substantial proportion of ethno-racial inequalities in substance use in Canada. The jump in substance use between racialized populations who immigrated to Canada and those Canadian-born highlights the importance of exploring within-group variability in deaths of despair risk and considering how intersecting forces including systemic racism shape substance use patterns across generations.

Abstract
ISSUES Non-medical prescription opioid use (NMPOU) contributes substantially to the global burden of morbidity. However, no systematic assessment of the scientific literature on the associations between NMPOU and health outcomes has yet been undertaken. APPROACH We undertook a systematic review evaluating health outcomes related to NMPOU based on ICD-10 clinical domains. We searched 13 electronic databases for original research articles until 1 July 2021. We employed an adaptation of the Oxford Centre for Evidence-Based Medicine 'Levels of Evidence' scale to assess study quality. KEY FINDINGS Overall, 182 studies were included. The evidence base was largest on the association between NMPOU and mental and behavioural disorders; 71% (129) studies reported on these outcomes. Less evidence exists on the association of NMPOU with infectious disease outcomes (26; 14%), and on external causes of morbidity and mortality, with 13 (7%) studies assessing its association with intentional self-harm and 1 study assessing its association with assault (<1%). IMPLICATIONS A large body of evidence has identified associations between NMPOU and opioid use disorder as well as on fatal and non-fatal overdose. We found equivocal evidence on the association between NMPOU and the acquisition of HIV, hepatitis C and other infectious diseases. We identified weak evidence regarding the potential association between NMPOU and intentional self-harm, suicidal ideation and assault. DISCUSSION AND CONCLUSIONS Findings may inform the prevention of harms associated with NMPOU, although higher-quality research is needed to characterise the association between NMPOU and the full spectrum of physical and mental health disorders.

Public health risks associated with methadone in Iran: A systematic review and meta-analysis. THE INTERNATIONAL JOURNAL OF DRUG POLICY 2021; 100:103529. [PMID: 34826790 DOI: 10.1016/j.drugpo.2021.103529] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2020] [Revised: 09/25/2021] [Accepted: 10/30/2021] [Indexed: 12/26/2022]
Abstract
BACKGROUND There has been a marked growth in methadone maintenance treatment (MMT) in Iran in the past two decades with positive health outcomes. We conducted a systematic review of studies on the prevalence of non-prescribed methadone use, methadone use disorder, and methadone-related poisoning and mortality in Iran. METHODS We searched International and Iranian databases up to May 2020 and contacted relevant experts. The pooled proportions were estimated through random-effects model. Methadone-related adverse outcomes were evaluated over time. RESULTS Sixty-five studies were included. The pooled estimates of non-prescribed methadone use in the last 12-month were 2.7% (95%CI: 0.9-5.4) and 0.1% (95%CI: 0.03-0.2) in the male and female general population, respectively. Among people who use drugs, 8.4% reported daily non-prescribed use in 2018. Four heterogeneous studies in drug treatment centers reported the existence of treatment-seeking for methadone use disorder. Methadone was responsible for 10.4% (95%CI: 4.5-18.3) of cases of acute poisoning in adults and 16.0% (95%CI: 9.3-24.1) in children. Methadone was reported as a cause of death in 53.5% of substance-related deaths referred to the Legal Medicine Organization while being the only cause in 35.8% of all cases. CONCLUSION Non-prescribed use of methadone in the general population is much less than opiates and some other available prescription opioids, like tramadol. However, notwithstanding the large and successful MMT program in Iran, increasing trends in methadone-related poisoning and deaths pose serious public health concerns. There is an urgent need to explore these fatal and non-fatal poisoning cases and implement policies to curb the harms associated with methadone use.

Abstract
BACKGROUND The aim of this study was to assess the epidemiological profile of unintentional opioid overdoses, the prevalence and number of psychotropic substances involved in opioid overdoses. METHODS This was a descriptive study, in which 180 participants were enrolled, and covered a nine-years-period. For collecting data was used the National patient electronic system "My term". The variables as gender, age, duration of opioid dependence, number of overdoses, type of substance, number of antidote ampoules, duration of hospitalization were analyzed. Severity of poisoning was made by using the Poison severity score. RESULTS Opioid overdose cases were significantly higher among males than females. Mean age with standard deviation (SD) was 32.23 ± 6.71 years. Mean years (±SD) of duration of opioid use disorder was 11.60 ± 5.89 years. The most commonly used primary substance was methadone in 68.89% and heroin in 31.11% cases. Twenty patients were treated with mechanical ventilation because of the severe respiratory depression. Poison severity score was moderate in 51.11%, severe in 45.56% and fatal in 3.33% of the cases. CONCLUSION Most of the cases, predominantly males used one or two substances. The combination of methadone and benzodiazepine was most frequently used and the most common way was by injecting the abused substances. In most of the subjects PSS score was moderate and severe with no differences between genders.

Abstract
OBJECTIVE Cannabis motivations have been studied extensively among patients of medicinal cannabis dispensaries, but less is known about motivations in community samples of opioid-using people who inject drugs. Our objective is to describe cannabis use motivations associated with self-treatment of physical pain, emotional issues, and as an opioid substitute. METHODS Data come from 6-month follow-up interviews with people who inject drugs who participated in a study on the efficacy of an injection initiation prevention intervention in Los Angeles and San Francisco, California from 2016-18. The analytic sample consists of 387 people who inject drugs who reported past-month cannabis use. We developed multivariable logistic regression models by reported cannabis use motivations: physical pain relief, emotional problems, and opioid substitute. RESULTS The most common cannabis use motivations reported by people who inject drugs was to "get high," relieve physical pain and emotional problems, and reduce opioid use. In separate multivariate models, using cannabis for physical pain relief was associated with higher odds of using cannabis as a substitute for opioids; cannabis for emotional problems was associated with being diagnosed with depression; and cannabis as a substitute for opioids was associated with non-prescribed, non-injection methadone use. CONCLUSION People who inject drugs reported using cannabis for health-related motivations. This motivation aligns with health needs and suggests the acceptability of cannabis use for health reasons in this population. Studies to determine the medical effectiveness of cannabis products for these common health and mental health needs among people who inject drugs are needed.

Abstract
Background: Illicit, nonmedical use of opioid agonist medications such as methadone is an ongoing concern. Yet, few studies have examined nonmedical use of methadone by people who inject drugs (PWID). Objectives: This study describes the prevalence of nonmedical methadone use in a community sample of PWID and examines factors associated with recent use of nonmedical methadone. Methods: A cross-sectional sample of PWID (N = 777) was recruited using targeted sampling and interviewed in California (2011-2013). Descriptive, bivariate, and multivariate logistic regression analyses were used to determine characteristics associated with nonmedical methadone use in the last 30 days. To determine if nonmedical methadone use was associated with overdose in the last 6 months, a separate multivariate analysis was conducted. Results: Among PWID sampled, 21% reported nonmedical methadone use in the last 30 days. In multivariate logistic regression analysis, nonmedical methadone use was associated with recent methadone maintenance treatment (adjusted odds ratio [AOR] = 2.86; 95% confidence interval [CI] = 1.90, 4.30), recent nonmedical buprenorphine use (AOR = 3.12; 95% CI = 1.31, 7.47), higher injection frequency (referent <30 injections; 30-89 injections AOR = 1.89; 95% CI = 1.19, 3.02; 90-plus injections AOR = 2.43; 95% CI = 1.53, 3.87), schizophrenia diagnosis (AOR = 2.36; 95% CI = 1.36, 4.10), recent non-injection opioid prescription use (AOR = 2.97; 95% CI = 1.99, 4.43), and recent injection opioid prescription misuse (AOR = 2.13; 95% CI = 1.27, 3.59). Nonmedical methadone use was found not to be associated with nonfatal overdose (AOR = 0.77; 95% CI = 0.38, 1.56). Conclusion: Nonmedical methadone use identifies a vulnerable subpopulation among PWID, is not associated with elevated nonfatal overdose risk, and evidences a need to expand methadone treatment availability.
