The most significant published criticism has been an article by Colin Mangham, the director of research for the Drug Prevention Network of Canada, in the online-only Journal of Global Drug Policy and Practice (JGDPP), which is said to be "posing as open-access, peer-reviewed scientific journal"    In the article Mangham claims that "the published evaluations and especially reports in the popular media overstate findings, downplay or ignore negative findings, report meaningless findings and overall, give an impression the facility is successful, when in fact the research clearly shows a lack of program impact and success."  He also claimed that interviews with area treatment centres revealed no referrals from Insite, and that police presence was deliberately bolstered in the area.  Based on this article, Tony Clement told an August 2007 meeting of the Canadian Medical Association that his belief that Insite should close had been reaffirmed. Clement stated that "there has been more research done, and some of it has been questioning of the research that has already taken place and questioning of the methodology of those associated with Insite."  The Journal of Global Drug Policy and Practice that Clement was referring to is run by the Drug Free America Foundation , and received much of its initial funding in a $ million grant from a . Department of Justice agency now under investigation for corruption. 
Injected medicines are commonly used in healthcare settings for the prevention, diagnosis, and treatment of various illnesses. Unsafe injection practices put patients and healthcare providers at risk of infectious and non-infectious adverse events and have been associated with a wide variety of procedures and settings. This harm is preventable. Safe injection practices are part of Standard Precautions and are aimed at maintaining basic levels of patient safety and provider protections. As defined by the World Health Organization, a safe injection does not harm the recipient, does not expose the provider to any avoidable risks and does not result in waste that is dangerous for the community.
