One can guess or assume a chemical imbalance.....but.....who can proove it? You say that there is indeed such a thing as chemical imbalance.....well prove me wrong & show me the lab results to back up your words. Ask your doctor to show you the lab results. I can bet ya a billion that you won't see them because they don't exist!!!! So, without proof....real scientific proof.....then I'm sorry, I can't believe it is real. If something is not proven to be real...not just speculative or assumed....then it can not be labeled a disorder or disease. Without being labeled a disorder or disease....all of the prescreptions are illegal. But somehow in this corrupt profession & the corrupt & paid off FDA....it happens every day through lies which infrindges on our right to informed consent. Behavioral problems in children most definately exist & vary per child. But that doesn't make them mentally ill. It makes parenting & schooling more of a challenge & requires more attention than the "good" behaved child. It seems that our society is so busy we've lost perspective on what really matters. Drugs are the easy way out & millions of Americans are suckered into their web of deception for profit. Doesn't anyone care that the long term effects of these drugs are not yet known??? Yeah...maybe for the right here & now they seem to be working.....putting a mask on the issue. But what about in the future? One can only "assume" what that holds with so many kids on substance II narcotics!
