I think to recall that T-Cloud was stated on one occasion to not be Terrigen Mist. Breathing N² all day long doesn't make us sick, but drinking water with a certain level of nitrate will do. I assumed same stuff here. And we can really state Terrigen, though direct inhalation or channeled exposure (cf. Terrigenesis, who require updates...), was really harmless to mutants. Different Terrigenesis taking, different side-effects ?
