poly vapor barrier?

I have installed kraft paper faced insulation in exterior walls. Should I also use a poly vapor barrier on this before I drywall and if so why?

We do all the time paper to the room and just a 2mil if you can find it. They did have it in 8'6" wide if you can find it. We do the ceiling first then the walls. then the drywall. the paper dont fit tight thats why ED
