So, according to definition, it can be considered an addiction. I think that there needs to be clarification with the definition then as many things can be classified as an "addiction."
You're right, this is an opinion and not only that, it is a question. I don't think that this is a ridiculous thread because by definition, there really is a fine line between what is considered an addiction and what is not. Like I said previously, humans are becoming addicted to numerous things so it could very much be possible that water could eventually become an addiction. I am not trying to offend anyone, this actually makes people think, as you can clearly see in this thread. 
This was a simple question I do not see the harm done. Please stop twisting my words. Addiction is a very serious issue. There are studies coming out now that say too much water is bad for you. Actually there are some cases where people fill themselves with only water and it makes them vomit. Too much water, or too much of a good thing can always be bad for you. For example, addiction to phones, that is a common thing now. People need it yes, but they deprive themselves of a normal social life and proper education and so it can also harm the person.
