From the article: "Graphite, the common form of crystalline carbon (the rarer one being diamond) is, in essence, a lot of layers of graphene piled on top of one another." So when you write by rubbing graphite on paper you leave behind graphene on paper.
- alexb_ 4y agoMakes sense. Although I would be surprised if pure carbon, of all elements, had a negative effect on our ability to live ROFL.

Many metals are simultaneously important in trace amounts and debilitating or fatal in larger (albeit still small) quantities. That's just for things that you are supposed to do, only too much of. Graphene is not useful or an important part of your body's functions; doing things you aren't even supposed to be doing with it (breathing it in, for example) can only have a negative effect. Speaking of pure carbon, carbon nanotubes are known to cause lung tumors.
