DARK MATTERS - DARK SECRETS is a continuing exploration into the area of melanin research. Melanin is commonly known as the substance that produces skin pigmentation, and this book will be valuable to any reader interested in the various effects of pigmented cells in the skin as well as in the central nervous system. Moore divides this book into two parts. In Part One (DARK MATTERS), a new and exciting perspective on the role of melanin in the skin is presented with a lengthy discussion on the pineal gland and the brain. In Part Two (DARK SECRETS), a biopsychosocial approach is presented to discuss drug addiction and how the drug binding capabilities of melanin can make a person more susceptible to the effects of some drugs.
