"We found significant reductions in public injection drug use, publicly discarded syringes and injection-related litter after the opening of the medically supervised safer injecting facility in Vancouver. These reductions were independent of law enforcement activities and changes in rainfall patterns.
"Our findings are consistent with anecdotal reports of improved public order following the establishment of safer injecting facilities and are not surprising given that a commonly reported reason for public drug use is the lack of an alternative place to inject and that IDUs who go to safer injecting facilities are often homeless or marginally housed. Our findings are also highly plausible since more than 500 IDUs visited the facility daily after it opened, and several feasibility studies have suggested that IDUs who inject in public would be the most likely to use safer injecting facilities. Our observations suggest that the establishment of the safer injecting facility has resulted in measurable improvements in public order, which in turn may improve the liveability of communities and benefit tourism while reducing community concerns stemming from public drug use and discarded syringes. It is also noteworthy that we did not observe an increase in the number of drug dealers in the vicinity of the facility, which indicates that the facility's opening did not have a negative impact on drug dealing in the area. Although further study of these issues is necessary, the safer injecting facility may also offer public health benefits, since public injection drug use has been associated with an array of health-related harms."

Vancouver's Insite

"Since its inception, Insite has been subject to an independent review by a team of physicians and scientists put in place to provide an 'arm’s length' evaluation of the program. The results of this scientific evaluation have been published in peer-reviewed academic journals and have indicated that Insite has reduced unsafe injection practices, public disorder, overdose deaths and HIV/Hepatitis while increasing uptake of addiction services and detox [8]. To date, there have been over three-dozen peer-reviewed papers evaluating Insite published making it one of the most evaluated healthcare programs in the history of Canada [9-38]. In light of the evidence, the program has garnered widespread support from Canadian physicians, scientists and healthcare professionals."

"Lifetime HIV-related medical care costs are approximately $210,555 in 2008 Canadian dollars (Pinkerton, 2010). Consequently, by preventing 5–6 HIV infections per year, the Insite SIF averts more than $1,000,000 in future HIV-related medical care costs. Andresen and Boyd (2010) estimate that the SIF generates $660,000 in additional cost savings by preventing 1.08 overdose deaths per year. The total savings due to averted HIV-related medical care costs and prevented overdose deaths (approximately $1.7 to $1.9 million per year), in and of itself, is just slightly greater than the estimated $1.5 million annual operating cost of the Insite SIF."

"The present study demonstrates that the opening of the Vancouver SIF was associated with a greater than 30% increase in the rate of detoxification service use among SIF users in comparison to the year prior to the SIF's opening. Subsequent analyses demonstrated that detoxification service use was associated with increased use of methadone and other forms of addiction treatment, as well as reduced injecting at the SIF."
