I believe that the reason most people use the terms interchangeably, is that
usually you are using arp-spoofing as the technique to allow poisoning of a
target's arp cache. You can use arp-spoofing for other purposes, and you
can poison arp cache using other techniques, but the two used together as
described above is by far the most common discussed.
