yea man needle exchanges are the best way to go IMO, its completely free. plus besides giving you needles they can help you in a multitude of other ways. I was really cool with the guys who ran my needle exchange in newark, they can help you find free rehabs/ detox's if you need em. Also most of them can give you or direct to place where u can get free STD testing. It is the best way you can go as far as harm reduction goes, they are only there for your best interest. Plus they give you a card that says it is legal for you to be carrying syringes even if you dont NEED them medically, so that always helps when it comes to getting stopped by the police. My dude used to hook me up with atleast 30 syringes everytime when i would see him, most places double the amount of your syringes everytime you go see them as long as you bring the old ones back. Needle exchanges are a god send!
