This is for me the best lecture I have ever sat through. He is an Author who writes likes a great books about our food. He is not a pot activist.
Wikipedia list this book Author as- Michael Pollan (born February 6, 1955) is an American author, journalist, activist, and professor of journalism at theUC Berkeley Graduate School of Journalism. A 2006 New York Times book review describes him as a "liberal foodie intellectual."I stumbled upon this youtube lecture he gave at UCLA after his book was released "Cannabis, The Importance of Forgetting, and the Botany of Desire".
He makes a great point of how much do we need to remember and what would be the purpose of forgetting.
