Not really. Second hand smoke is relatively harmless unless you are stuck in a very smokey environment every day for years. Fluoridated water is hard to avoid, usually costs money to avoid, and you are exposed for your whole life. Smoke is a much more obvious toxin than fluoride because you can smell it, and it's irritating to most people at first. Fluoride in water is completely unnecessary thanks to fluoridated toothpaste, yet we continue to add it. There are other countries, even in Europe, that don't do it out of concern for the health effects of the toxin. Yet people call it a conspiracy theory anyway...
