I certainly agree with what you're saying about the feedback loops, as long as you're able to manipulate the loop into healthier behaviour then it doesn't really matter where in the loop you intervene. My issue with pharmaceuticals is that they are used completely inappropriately. There are people who have neurochemical imbalances which do require pharmaceutical intervention. Taking the USA as an example though there is a huge proportion of the adult population taking pharmaceuticals for psychological issues. Many of these issues are related to what you might call experiential issues i.e. they're not happy with the circumstances of their life. In these cases there is no physiological issue that requires correction, the brain is functioning correctly. The issue is with the configuration of the neurons and while drugs can encourage reconfiguration in a particular direction (happier say), it would be far more useful if those individuals could learn to deal with the hardships of life without external intervention.
