Stickin' needles in my arteries
There could be two things thats Nas is saying here.
This is a continuation of the last line and he is referencing how when practicing voodoo people use a doll and stick it with needles.
Heroin is commonly injected through the veins/arteries in one’s body. This explanation could go with the previous line also, by saying that, like how heroin takes control of people’s lives, his life is being taken over. The heroin allusion can also work in conjunction with the succeeding line of ironically not being able to feel it, as heroin is a powerful opiate.
