The devil is in the details:

First, confirmation that my concern is valid and your previous dismissals of my "anecdotal" claims where arrogant BS:
Second, this study does not measure what you think it does: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.
You responded to a more recent meta-analysis of 47 separate studies with a single study dating back to 2006 and you have the nerve to try to lecture anyone on here about scientific validity? Get the
**** outta here.
