I am on a community committee for a safe injection site. They have shown us a graph showing more people are using the site. I have asked for the same chart to include a metric showing that more people are using the site and there are less overdoses or medical interventions or another metric showing more people using the site results in some sort of quantifiable metric of community benefit. The public health authority who provides the graphs is unable or unwilling to provide the information and charts I want. I thus worry that data is selectively used to prove a predetermined narrative.
