"Don't think for a minute that we still have WMD," he [Saddam] told his deputies. "We have nothing."
Here's an interesting article that discusses the search for WMD's from Saddam's point of view. Apparently, some documents found after the invasion have been translated and recently made public. These documents make it clear that the WMD’s were indeed destroyed after 1991.

Here’s an excerpt:
Scores of Iraqi documents, seized after the 2003 invasion, are being released at the request of the U.S. House Intelligence Committee chairman, Rep. Peter Hoekstra, who has suggested that evidence might turn up that the Iraqis hid their weapons or sent them to neighboring Syria. No such evidence has emerged.
Repeatedly in the transcripts, Saddam and his lieutenants remind each other that Iraq destroyed its chemical and biological weapons in the early 1990s, and shut down those programs and the nuclear-bomb program, which had never produced a weapon.
