from the "al wailing Wall Street Journal, 2059."
"Graphene wonder material companies in court, again facing a class action lawsuit, as it transpired the executives knew for 20 years, microparticles of dust from it, causes Mesiothelioma, and were continuing to make it for a vast profit, (peace be unto it.)"
Obviously there's no evidence for this, but if history has shown anything, it's that microparticles, such as asbestos, MDF etc, cause problems with breathing.
