Dopamine and Self-Destructive Behavior
There are so few accurate, clear, and useful resources online. Here is an interview with Dr. Anna Lembke of Stanford University about dopamine that I think does a good job explaining and exploring concepts. This interview is long, but worthwhile! A couple of parts may not be suitable for young children. Though I generally have a nitpick about the difference between addiction and compulsion, Dr. Lembke gives her operational definition of addiction, and is consistent with regard to that definition. She thoroughly and compassionately addresses the roots of addiction (which includes video games and overeating, not just drugs), and gives a specific intervention for turning things around.
