Are mages and curse users able to die of sickness

lets say a mage or curse user smokes a lot, can they die of lung cancer?

what was that one virus that tore and broke magic users from the inside out with their own element

this?

yes
I wish that was added…

Mage yes. Curse user I honestly don’t know, their lungs transform to dodge the smoke?

Imagine metal mages doing heavy shot to people gifting them mecalepsyia, lol.

ngl i would dig being frozen inside out with ice magic
