Are you assuming that Bruce is right and lung damage does occur due to ingestion?
I don't think Bruce has any evidence for this and Catlin likely misunderstood what CDC said, after all theres nothing about any lung damage from ingestion of either chlorite or chlorine dioxide in the ATDSR report and I don't see how there would be any difference with Miracle-Mineral-Supplement , so as far as I'm concerned it's not worth pursuing
