Nicotine, alcohol, and gambling—three very common addictions—are among the most preventable causes of premature death through illness or suicide in the U.S. In this program, doctors from Brown University’s School of Medicine and Harvard Medical School talk with host Kat Carney about the psychological, physiological, and genetic components of addiction while considering treatments such as hypnotherapy, Naltrexone therapy, and experimental vaccines. Some of the medical outcomes of addiction, including lung cancer, cirrhosis of the liver, and clinical depression, are also discussed, as well as a new form of dependency: addiction to the Internet.
