More than 20 million teenagers and adults are addicted to alcohol or drugs in this country. Some go to residential treatment programs, while others turn to outpatient programs in their communities. But the vast majority of people who need help don’t get any at all. In a new book, health and medical writer Anne Fletcher describes what goes on inside many different kinds of rehab programs. She joins us to talk about the challenge of finding effective addiction treatment. We’ll also hear from the head of a residential care facility and a director of an outpatient addiction treatment center. Please join us to discuss the challenges of getting help for drug and alcohol addiction.
