On this edition of Clean and Sober Radio, host Gary Hendler and cohost Mark Sigmund are joined by friend of the show, Stephen Sussman. Stephen is the identical twin of David Sussman who was a regular guest on the show and occasional cohost. Sadly David, who had been clean and sober for fifteen years, passed away four years ago from an ongoing illness. Gary grew up with the Sussman boys. David was a fast friend, Stephen hung with another crowd. Gary and David became addicts, Stephen became a world recognized scholar in the education field, a philanthropist, and sits on many international boards. The underlying question is, does genetics play any role in addiction? Some say yes, some say no. Stephen provides some interesting information on the subject. An interesting show full of memories and insight.
