Actually, not from the movies but from the comics. After Magneto removes all the adamantium from Wolverine, and he recovers, he discovers that his healing powers are 10 times more powerful than before. That's when they discover adamantium is toxic and Wolverine's body was wasting its healing powers by constantly fighting the poison of the metal. (Yes, it's a bit sad I know all this ;P)
