It might be structurally similar to asbestos fibrils but asbestos is directly carcinogenic. Carbon microstructures probably aren't (unless it's carrying something that is).

It might still donk your lungs up if it can't be absorbed. Functional inflammation, COPD if you inhale a lot. Abrasive cancers in long term, repeated exposure.

Aerosolising it seems, I agree, far too risky. A sheet or liquid alcohol-evaporative application makes more sense.
