> sometimes there's just an imbalance. What does that mean? As far as I know, there has never been medical science to support this statement. I understand drugs 'work' in the sense people's experience and emotions are altered -- that's beyond debate. But we don't know what it means in terms of "depression" or "happiness" or other promises they make. I'll feel great if I spend my day high on cocaine but I am not going to claim I cured my depression while under the influence.
