Irregardless is a word but you shouldn't use it. It's a double negative, as in "not regardless", so you actually give regards to something. If your point is that something is independent of another thing, then say "regardless" and sometimes even "irrespective". Never "irregardless."

I am craving for chocolate. WRONG
I have a craving for chocolate. RIGHT
I am craving chocolate. RIGHT
  A craving for something >> craving as a noun
  Craving something >> craving as a verb

There is no "h" or "w" in "po", you hooligans.
