If we start to have huge amounts of it spread through house objects, than yeah, we can increase people's exposure by a large multiplier and get the known harmful effects we already know about.

That said, I don't think we will ever have large amounts of it in house objects. Graphene doesn't seem to be useful that way. We may have it embedded in some material, but that will limit exposure to waste management and manufacture.

Also, differently from asbestos, graphene is not chemically stable. So very small pieces of it have a limited half-life.
