Losing the uphill battle? Emergent harm reduction interventions and barriers during the opioid overdose crisis in Canada

Canada continues to experience an escalating opioid overdose crisis that has claimed more than 8000 lives in the country since 2016. The presence of the synthetic opioid fentanyl and its analogues is a central contributor to the increases in preventable opioid-related deaths. However, a number of converging social-structural factors (e.g., the continued criminalisation of drug use, political changes) and political barriers are also complicating and contributing to the current crisis. We briefly outline four harm reduction interventions (i.e., injectable opioid agonist treatment, naloxone distribution programs, overdose prevention sites, and drug checking services) as emerging and rapidly expanding responses to this crisis in Canada. These examples of innovation and expansion are encouraging but also occurring at the same time that the opioid overdose crisis shows few signs of abating. To truly address the crisis, Canada needs political environments at all government levels that are responsive and foster harm reduction innovation and drug policy experimentation.     

Should harm minimization as an approach to adolescent substance use be embraced by junior and senior high schools?: Empirical evidence from An integrated school- and community-based demonstration intervention addressing drug use among adolescents

The objective of this demonstration project was to determine if school-based harm minimization drug education was potentially acceptable and effective for junior and senior high school students in Nova Scotia. We conducted a four-year quasi-experimental intervention using mixed quantitative and qualitative methodologies. The intervention was a co-operative participatory research project with various activities determined by the participants. The project involved a partnership of four schools, two school boards, two regional addiction services, the provincial department of health, and a university. The outcomes evaluation was based on a sample of 1117 and 849 students in the intervention schools, compared with 3755 and 4247 students in the rest of the province, in 1998 and 2002, respectively. The evaluation of acceptability was based on an analysis of 491 documents generated from 1998 to 2002. The outcomes of effectiveness were specific risks and harmful consequences associated with substance use. We found that harm minimization was an acceptable approach to drug education targeting the senior high school population, and there was also some evidence of effectiveness in that age group in that the prevalence of several risks and negative consequences of substance use decreased significantly in the intervention schools relative to the rest of the province. In junior high school, harm minimization was found to not be an acceptable approach to drug education. This demonstration project provides evidence that school-based harm minimization may be acceptable and effective in senior high schools but may not be acceptable in junior high schools.     

Association between A218C polymorphism of the tryptophan-hydroxylase-1 gene,harm avoidance and binge eating behavior in bulimia nervosa

Genes involved in serotonin transmission are likely involved in the biological predisposition to bulimia nervosa. We investigated whether the A218C polymorphism of the tryptophan-hydroxylase-1 gene was associated to bulimia nervosa and/or to some phenotypic aspects of the disorder. One hundred eighty Caucasian women (91 patients with bulimia nervosa and 89 healthy controls) were enrolled into the study. They underwent a blood sample collection for A218C polymorphism of the tryptophan-hydroxylase-1 genotyping and a clinical evaluation assessing comorbidity for Axis I and II psychiatric disorders, harm avoidance personality dimension and bulimic symptoms. The distribution of both tryptophan-hydroxylase-1 A218C genotypes and alleles did not significantly differ between patients and controls. Bulimic women with the AA genotype exhibited a more severe binge eating behavior and higher harm avoidance scores than those with CC genotype. These findings support the idea that tryptophan-hydroxylase-1 A218C polymorphism does not play a part in the genetic susceptibility to bulimia nervosa, but it seems to be involved in predisposing bulimic patients to a more disturbed eating behavior and higher harm avoidance.     

Direct and indirect acquisition of syringes from syringe exchange programmes in Baltimore, Maryland, USA

Syringe exchange programmes (SEPs) are a fundamental source of sterile syringes and other health services for injection drug users (IDUs). However, various obstacles prevent many individuals from obtaining syringes from this source. As a result, some IDUs acquire syringes from “secondary exchangers”. The current study assessed the acquisition of syringes from the Baltimore City Needle Exchange Program (BNEP) as well as factors associated with obtaining syringes from the BNEP. Participants were asked to identify the colour of the cap of the most recently obtained syringe (red or grey cap suggested BNEP origins). In addition, support and risk network variables were examined. Although 38% reported using a syringe with a grey or red cap, only 7% reported that the BNEP was their primary source of syringes. Multivariate analyses showed that reporting the most recent syringe cap as red or grey was associated with obtaining syringes from the BNEP, obtaining syringes from a spouse, obtaining syringes from friends/neighbours, and number of drug users in their network. Based on these findings, encouraging secondary exchange is an effective method of providing injectors with syringes.     

Workaholism is still a useful construct

Medical provision of orally-administered stimulants is a harm reduction technique that could reduce suffering and slow the spread of AIDS among cocaine misusers in Vancouver, B.C., Canada. However, experimentation with stimulant maintenance will be difficult to carry out until the public's exaggerated fears of cocaine and other stimulants, engendered by a prolonged “War on Drugs”, have subsided. This article explores the prospects for stimulant maintenance by (1) reviewing the actual dangers and benefits arising from use of cocaine and other stimulants, (2) describing small scale stimulant maintenance programs that already exist in various countries, and (3) drawing from Vancouver's experience with methadone maintenance to propose first steps towards stimulant maintenance. Although we focus our analysis on Vancouver, we believe it has wider applicability.     

Candour for surgeons: the absence of spin

Doctors are exhorted to be candid with their patients when clinical errors occur. This paper discusses the history of candour in surgical law as well as recommendations resulting from the Mid Staffordshire public inquiry. It also looks at why candour is necessary and where the threshold should lie. Provided surgeons understand that a duty of candour is engaged at a certain threshold of harm, then disclosure of misadventure to patients or their relatives becomes simply a matter for clinical judgement, just in the same way as a surgeon judges which potential operative complications need to be disclosed during the consenting process.     

CROSS-CULTURAL APPROACHES TO HARM REDUCTION RESEARCH: SOME CONSIDERATIONS ON THE BRAZIL EXPERIENCE

Harm reduction initiatives for drug users comprise a range of approaches, including drug-user treatment, advocacy for changes in drug policy, needle exchange programs, bleach distribution, and broad-based interventions that focus on both safer drug use and less risky sexual behaviors. In many developing nations, harm reduction is a relatively new strategy, which focuses almost exclusively on the connections between drug use and the spread of HIV infection. In Brazil, harm reduction programs are few, and little has been documented about their scope, experience, and effectiveness. This paper reviews the status of Brazilian harm reduction initiatives in general, with a specific focus on lessons learned from the conduct of cross-national research in Rio de Janeiro. The study demonstrated the feasibility of implementing a community-based prevention program among an at-risk population of cocaine users in Brazil, and in other countries where there is little tradition of research with out-of-treatment drug users. Finally, the paper addresses aspects of the harm reduction movement that tend to hamper its progress in both developed and developing nations.
