From the study itself:

The devil is in the details:

First, confirmation that my concern is valid and your previous dismissals of my "anecdotal" claims where arrogant BS:

In September 2003, the first safer injecting facility in North America opened in Vancouver, Canada. Here, injection-drug users can inject preobtained illicit drugs under medical supervision.1 A concern regarding such facilities is that they may lessen the likelihood that injection-drug users will seek addiction-treatment services.

Second, this study does not measure what you think it does:

In multivariate analyses with the use of Cox regression, an average of at least weekly use of the supervised injecting facility and any contact with the facility's addictions counselor were both independently associated with more rapid entry into a detoxification program

The key element here is contact with an addictions counselor and access to detox - not SIS itself.

More importantly, the comparison is between users of the SIS - there is no data comparing the users of the SIS to what would happen if the same addictions counselors and detox services were made available without the SIS.

This is a good example of how you misrepresent scientific knowledge in order to advance your pet ideological objectives while denigrating people who call you on your BS.
