"The British Columbia Centre for Excellence in HIV/AIDS was commissioned to evaluate Insite. A study published in 2006 showed that there was an increase in uptake of detoxification services and addiction treatment.13 Another study published that year showed that Insite did not result in increased relapse among former drug users, nor was it a negative influence on those seeking to stop drug use.14 Results of studies using mathematical modelling showed that about one death from overdose was averted per year by Insite.1 A subsequent study estimated 2–12 deaths averted per year.15 Although these studies did not have sufficient power to detect any difference in incidence of blood-borne infections, Kerr and colleagues did find that Insite users were 70% less likely to report needle-sharing than those who did not use the facility.16 Before the opening of Insite, those same individuals reported needle-sharing that was on par with cohort averages. As for public order, Wood and colleagues found that there was no increase in crime following the opening of the facility.17 In fact, there had been statistically significant decreases in vehicle break-ins and theft, as well as decreases in injecting in public places and injection-related litter."
