I'm still a little worried about the toxicity of graphene-based products that they might turn out to be another "asbestos".

[BizarroLand]

Asbestos is entirely safe as long as it is non-friable. If graphene has similar risks it should also have similar safeties. Don't huff graphene dusts.

[bryant]

is there any reason to be concerned about graphene that wouldn't apply to common pencil lead (graphite)?

[LunaSea]

Usage duration and frequency?

[speerer]

Only on HN are graphite pencils used less frequently than graphene tech.

[LunaSea]

Well most people use pens instead of pencils.
