Dr. Anna Lembke on why this age of abundance is wracked with addiction

We live in a world of constant convenience, where  just about any material need can be met with a simple click of a button or a swipe on a phone screen. But what if this relentless pursuit of momentary pleasures is actually becoming the source of some of our greatest pains? On this edition of KCBS In Depth, we speak with Dr. Anna Lembke, the medical director of Stanford Addiction Medicine. Her new book is "Dopamine Nation: Finding Balance in the Age of Indulgence," in which she turns to brain science and the science of addiction to explore the root cause of both pleasure and pain and why it is that this time of instant gratification seems to have thrown our dopamine systems so out of whack.
