even tho it hasnt been officailly stated in that regard, for my money, low frequency radiation seems to be the best bet. in fact, it has been stated in comics a few times that wolverine's healing factor is actually working overtime becuz it is being taxed by the prescnce of the metal in his body. his system views it the same way ours view foreign bodies, and fights against it.
that makes sense seeing as how when he had that run in with the "native" and actually got her pregnant, when the black ops ppl got her to the lab they had to poison her with radiation to distract her healing factor while they harvested her fertilized embryos.
tho it makes a little sense, i still have major problems with any exlpnation that wolverine had any sort of poisioning, cuz if you all remember the reason bullseye even came back to normal was becuaz that japanese mafia guy gave him adamantium bones in return for killing daredevil, and bullseye damn sure doesnt have a healing, factor. grant it he doesnt seem to have the bones anymore(not an official retcon it was just never brought up again)
plus all the other charcters with a hint of adamantium, off the top of my head
sabretooth
x-23
cyber
deathstrike
and none of these ppl have any reported cases of poisoning
MANJARO HAS SPOKEN!!
