Another conspiracy theory takes a win:

Health Canada has issued an advisory and asked distributors to recall masks sold with graphene or biographene in them over potential inhalation risks.

Graphene is comprised of a single layer of carbon atoms and is considered a nanomaterial, meaning it is made of tiny particles, and is reported to have “antiviral and antibacterial properties,” the advisory says.

Health Canada said it conducted a preliminary scientific assessment after becoming aware that masks containing graphene were being sold with COVID-19 health claims and used by adults and children in schools and daycares. Health Canada also believes they may have been distributed for use in health care settings.

The products affected are listed as “face masks labelled as containing graphene or biomass graphene,” the advisory states. Health Canada recommends that Canadians not use masks with the substance and to consult their health-care provider if they have used graphene face masks and have health concerns – such as new or unexplained shortness of breath, discomfort or difficulty breathing.

The specific mask model under review, #SNN200642, is the same model for which Health Canada received a complaint from a concerned citizen raising a question about the potential health risks.

The organization said that their preliminary assessment of available research found that inhaled graphene particles had some potential to cause “early lung toxicity” in rats and other animals, but that the potential for people to inhale graphene particles – and the related health risks – are not yet known, and may vary with based on mask design.
