Federal funding for harm reduction but not for syringes???

In December of 2009 The Consolidated Appropriation Act ended an almost 3 decade long ban on federal funding for harm reduction. Harm reduction for those of you who may not know about it is a different approach to deal with illegal drug users in our country i'm focusing on heroin users and syringe exchange programs (SEPs). SEPs are were people can exchange dirty needles, potentially HIV-contaminated needles for clean ones. If you don't think heroin is a big problem in america well in 2002 there were over 166,000 heroin users some as young as 12 years old by 2012 this number increased by 50% with 335,000 heroin users. Harm reduction programs have been used in many parts of Europe and recently Canada and now here in the U.S. Before December of  '09 SEPs could only be set up and funded by state and local governments. Now the federal government has decided to help fund them but they refuse to fund any money to the purchase of clean syringes. I just can't seem to think of any reason for this. The federal government finally agrees to help by paying for employees and facility's and anything else these programs need but not the actual syringes the number one thing these programs need.
