Dr. Lester Grinspoon is associate professor emeritus of psychiatry at the Harvard Medical School. He researched the medicinal legitimacy of the marijuana prohibition 45 years ago and discovered that an immense chain of lies served as a base for sending millions of people to jail. Since then he became an advocate for telling the truth about marijuana.
I had a telephone interview with him at the end of august 2015. This is my transcript of our Skype conversation.
