Ni200 Nickel is a contact allergen, in other words you have to touch or ingest the nickel.
Ni200 Nickel does not give off fumes at the temperatures people vape at, it doesn't produce gas at those low temperatures, in fact it would have to be close to molten nickel before producing gas that is why the people who suffer from respiratory problems related to nickel fumes are generally people working in the foundry and welding industries.
