What is a poison? Poison is dosage related and fluoride at a safe dosage is not a poison. Pure drinking water can be a poison when one is overdosed. Do remember the Wii contest of a few years ago and a lady died from drinking too much water? If one uses the term poison one needs to address dosage. We also add chlorine and pot ash to the drinking water and chlorine has the potential to be a much greater poison then fluoride. The anti fluoride folk are making money on sell their books

Not on FR they don't.

These threads pop up a couple times a year, with the same arguments every time.

Thank you at last sanity on the thread. Toxins require 4 components and not just one: 1) Toxicity - or the harmfullness that it can cause. 2) Dosage - the amount to which one is exposed. 3)Duration - the length and number of times of exposure. And 4) An entry way into the body.

For example: Lead is not harmful outside of the body, used the material all the time to make things. Don’t ingest it though. However, naturally occurring/unconcentrated dosages that do not have routine reoccuring exposures aren’t harmful.

Example 2: Cyanide (derived from almonds) very toxic minimal dosage is lethal. Duration doesn’t come in to play.

Example 3: Carbon Monoxide - deadly in high concentration and exposure, not deadly in naturally occuring amounts - it’s in the air we breath

Example 4: Milk - Cow’s milk was shown to be carcinogenic in the 70’s or 80’s in mice. Provided they forcefed the mice a gallon a day for a month. DOSAGE and DURATION.

Finally there are some poisons that one can build up a tolerance to by taking very small portions and building up resistance and higher dosages over time. I wouldn’t recommend it, but .... the body is an amazing thing.
