To me this song is about after someone you love dies, turning to drugs (needles) to deal with pain and make it go away. Perhaps this person who died was themselves a drug addict so you feel you need to recreate the atmosphere that they themselves were once immersed in order to feel closer to them (endure their same life of drugs and strife). In a sense, you end up likely killing yourself in order to be able to come to terms with the loss. Furthermore, the pain of losing them can only be resolved by you in some way causing your own self pain.
