RE:RE:Why The SP Dropped So Fast Good point. But remember the company and any other graphene using company has no imperical data on extensive use of the human lung.
Medical research going back 10 years has identified graphene highly toxic to human lung tissue . 2012 study.
Big issue is the supply and demand crisis some posters are playing up. Just does not exist anymore. As of September 2020 Canada had 50% of it's PPE covered domestically and now in 2021 should be close to 100%. Add expontential growth in the US and the rest of the world and there will be a PPE glut in 2021
The surge of companies making PPE for the covid crisis has mushroomed and now they are starting to starve.
