"Throughout the human life span there remains a constant two-way interaction between psychological states and the neurochemistry of the frontal lobes, a fact that many doctors do not pay enough attention to. One result is the overreliance on medications in the treatment of mental disorders. Modern psychiatry is doing too much listening to Prozac and not enough listening to human beings; people’s life histories should be given at least as much importance as the chemistry of their brains. The dominant tendency is to explain mental conditions by deficiencies of the brain’s chemical messengers, the neurotransmitters.
As Daniel J. Siegel has sharply remarked, “We hear it said everywhere these days that the experience of human beings comes from their chemicals.” Depression, according to the simple biochemical model, is due to a lack of serotonin — and, it is said, so is excessive aggression. The answer is Prozac, which increases serotonin levels in the brain. Attention deficit is thought to be due in part to an undersupply of dopamine, one of the brain’s most important neurotransmitters, crucial to attention and to experiencing reward states. The answer is Ritalin. Just as Prozac elevates serotonin levels, Ritalin or other psychostimulants are thought to increase the availability of dopamine in the brain’s
prefrontal areas.
This is believed to increase motivation and attention by improving the functioning of areas in the prefrontal cortex. Although they carry some truth, such biochemical explanations of complex mental states are dangerous oversimplifications — as the neurologist Antonio Damasio cautions: "When it comes to explaining behavior and mind, it is not enough to mention neurochemistry... The problem is that it is not the absence or low amount of serotonin per se that “causes” certain manifestations.
Serotonin is part of an exceedingly complicated mechanism which operates at the level of molecules, synapses, local circuits, and systems, and in which sociocultur

It is time to realize, then, addiction is neither a choice nor an inherited disease, but a psychological and physiological response to painful life experiences. It can take many forms, but whatever form it takes:
• it employs the same neurological pathways and emotional patterns;
• the damage it does extends well beyond the suffering imposed by drug use specifically;
• to ostracize the drug addict as somehow different from the rest of us is arrogant and arbitrary;
• to criminalize certain substances, say heroin, while allowing the profitable distribution of more deadly products such as cigarettes is irrational and harmful—yes, though it may be a startling assertion it is medically a simple fact: heroin use, short of overdose, is far less lethal than cigarette smoke;
•to treat the addiction, which is a symptom, without treating the pain that underlies it is to deal in effects rather than in causes, and therefore dooms many to ongoing cycles of suffering.
