I agree that legalization/regulation should be the end goal but it isn't a prerequisite for creating connections between addicts and health care services. In many of the western european countries there have been "drug consumption rooms" for decades now and the general opinion about them seems to be very positive[1]. They are essentially supervised rooms where addicts can get clean needles and use their drugs in a clean and supervised setting as well as having a change to speak to social workers if they want to.

I don't know if Oregon has any system like that in place right now. If they don't, it would seem like the reasonable first step considering that one of the major complaints seems to be drug use in public.
