Was Pope John Paul I poisoned by the CIA after 33 days reign?

I heard this today and wanted to check the voracity of this statement. Where best but Yahoo answers?
Update: The Vatican is historically Pro-USA, this particular pope was intent on looking into the Banking and Financial affairs of the Vatican. It is true that an Orthodox Russian Priest was poisoned in his presence a week earlier. No autopsy was ever held on this Pope and he was embalmed less than 5 hours after his death.
