In nj due to the heroin epidemic (not that its contained to nj) they have places where you can go get fresh syringes for free and you bring back the old ones and exchange for new ones. Sadly they are located in the roughest cities (newark, paterson, trenton, camden) and are obviously flooded with shady characters. You go in there juiced outta your mind and youll look like the junkie of the bunch. Hahaha
