Impact of supervised injection facilities on community HIV levels: a public health perspective

Supervised injection services: what has been demonstrated? A systematic literature review

BACKGROUND

Supervised injection services (SISs) have been developed to promote safer drug injection practices, enhance health-related behaviors among people who inject drugs (PWID), and connect PWID with external health and social services. Nevertheless, SISs have also been accused of fostering drug use and drug trafficking.

AIMS

To systematically collect and synthesize the currently available evidence regarding SIS-induced benefits and harm.

METHODS

A systematic review was performed via the PubMed, Web of Science, and ScienceDirect databases using the keyword algorithm [("supervised" or "safer") and ("injection" or "injecting" or "shooting" or "consumption") and ("facility" or "facilities" or "room" or "gallery" or "centre" or "site")].

RESULTS

Seventy-five relevant articles were found. All studies converged to find that SISs were efficacious in attracting the most marginalized PWID, promoting safer injection conditions, enhancing access to primary health care, and reducing the overdose frequency. SISs were not found to increase drug injecting, drug trafficking or crime in the surrounding environments. SISs were found to be associated with reduced levels of public drug injections and dropped syringes. Of the articles, 85% originated from Vancouver or Sydney.

CONCLUSION

SISs have largely fulfilled their initial objectives without enhancing drug use or drug trafficking. Almost all of the studies found in this review were performed in Canada or Australia, whereas the majority of SISs are located in Europe. The implementation of new SISs in places with high rates of injection drug use and associated harms appears to be supported by evidence.

Implementation of possession laws and the social ecology of tobacco control

The objective of this evaluation research was to assess the impact of programs intended to support the enforcement component of a comprehensive youth tobacco control. The research method was a survey of a randomly stratified cluster sample of law enforcement officers. Results of the evaluation showed that the enforcement behaviors of officers were increased through the state programs to support tobacco enforcement activities. The study showed that support for implementing a policy is important to achieve the objectives of a policy. The results of a study of the enforcement component of a Florida tobacco control program are reported and discussed within the ecological context of previously reported enforcement-linked decreases in youth tobacco use and funding and defunding of the Florida Tobacco Control Program.

Transition to injection drug use among street youth--a qualitative analysis

OBJECTIVES

To examine social contexts and processes influencing transition to drug injection among street youth.

METHODS

42 street youth participated in in-depth interviews. A typology of experiences was built founded on youth's street life and drug use trajectories. The transition to drug injection was examined through these experiences.

RESULTS

We identified five types of mutually exclusive experiences. The "downtowner's" experience is characterised by early street life and drug consumption trajectories, and a strong identification with the downtown milieu. These youth progress from one drug to another and, in a milieu where drug injection is omnipresent, this escalation culminates in transition to injection. The "tripper" street life and substance use trajectories begin later and are less intense. Most "tripper" youth are already chronic hallucinogens users when they arrive in downtown Montréal. Although they judge "junkies" severely, they show some ambivalence towards injection. The "on the go" experience is characterised by trajectories of drug use and street life that are intermingled, leading to a loss of control. These youth, who often have serious delinquent behaviours, come to downtown Montréal to party and consume drugs, mostly stimulants. Their drug use pattern and network make them at high risk of starting cocaine injection. The "hard-luck's" experience is characterised by a lack of identification with the downtown milieu. These youth who use drugs recreationally, end up in the streets accidentally, often because of unemployment. The "alcoholic' experience is related to alcohol misuse. These youth usually end up in the streets due to this dependence. Their street involvement is mostly an experience of solitude. The risk of transitioning to injection for both these types is low.

CONCLUSIONS

Some combinations of street life and drug use trajectories seem to contribute to injection among street youth. Some important factors interact and increase the risk of street youth transitioning to injection: poor personal assets; early rupture with primary social institutions; social integration into subcultures where both street life and "drug trips" are fashionable, drug preferences and the local drug market.
