Fluoridation contaminates the water you use in any way you use it. It poisons you and in very small doses so you barely notice it. It's the fluoride ion that gets released in the water that poisons you.
Anyone LIVING in, WORKING in, or VISITING Ottawa is exposed to this illegal drug pushed by promoters who do not understand the implications that it causes harm because it's a protoplasmic poison.
That means it destroys the very cells that make you up from all foods and beverages you consume and through your skin every time you wash in any way using fluoridated water. You breathe it in from the vapor when showering, the sauna, the hot tub and the swimming pool.
