I'm deeply curious about where you expect a city to find the money for "forced rehab" when you're belittling me about making "adult...tradeoffs."
Also, where do you think the money for emergency response to drug overdoses comes from, exactly? Do you expect that having a trained professional on hand to administer Naloxone in event of an OD would be more or less expensive than a 911 response?
Here's a great editorial from the Seattle Times's op-ed page, which isn't exactly known for being liberal: http://www.seattletimes.com/opinion/editorials/bring-heroin-...
And a great quote:
The [safe injection] model has worked in Vancouver, B.C.
One study estimated the Insite facility in Vancouver’s
Downtown Eastside prevented 83 HIV infections, saving
the government at least $17 million. Others document a
reduction in overdoses.
Lastly, the people who use the site need to be given the chance to get into treatment if they want it. Forced rehab, as you describe it, doesn't seem to have the effect that you'd like it to. I found this study from UCLA which indicates that the evidence in favor of legally mandated rehab programs is murky at best:
