Dr. David Nathan, a psychiatrist in Princeton, NJ and a clinical assistant professor at Robert Wood Johnson Medical School is our expert guest today. This week’s topic is legalization and decriminalization of marijuana from the perspective of a professional in the field of Addiction. Dr. Nathan had written an article in 2010 for the Wall Street Journal discussing this topic. I was curious about his perspective now, with the various states legalizing medical marijuana and some states recreational marijuana. He recently wrote another article for CNN where this is discussed and in this interview we talk about the topic and controversy as it stands today.
