Not that the ban's reinstatement can be blamed solely on Republicans, certainly not in the Democratically-controlled Senate. It happened in part because Democrats did not make it a priority to keep it from happening.
Congress's action this week means misery and death for large numbers of people. As the eight federal reviews of the research  on this issue demonstrate, needle exchange programs reduce the spread of HIV without increasing the use of drugs. According to the Harm Reduction Coalition , needle sharing by injection drug users accounts for 8,000 new cases of HIV and 15,000 new cases of Hepatitis C each year. Of course the diseases spread from them to other people on occasion, including people who have no involvement in illegal drug use. As HRC points out, New York City has seen a 75% reduction in new HIV cases as a result of instituting such programs, according to a 2005 study.
So let's be clear; the evidence is overwhelming. In fact, even the studies cited by opponents of needle exchange actually support needle exchange , if you take the time to read them. Reinstituting the federal ban will have the effect of defunding many programs, and the science is clear that this means more infections and more needless of life. It won't save the federal government any money, because it doesn't affect the total amount of funding in the Ryan White program. All it does is make the program less effective at accomplishing its goals. And of course, health care costs will only grow because expensive AIDS and Hepatitis treatments will be needed for more people. Sadly, expressing the drug war ideology through deadly legislating seems to be more important for certain members of Congress than any of that. On the bright side, at least they didn't reinstate the old ban on the District of Columbia spending its own funds on needle exchange programs .
Don't give up and don't think that it's over. The ban got repealed once, and it will get repealed again. In the meanwhile, here are a few of the statements about the event that have come to my attention since yesterday. (Feel free to link more in the comments section.)
