Carrying The Family Torch In Cannabis with Dan Herer. Dan is the son of famous marijuana activist and author Jack Herer, of the book ‘The Emperor Wears No Clothes’, who passed away in 2010. Dan balances multiple roles as an industrial hemp developer, hemp entrepreneur, and is the Director of the California-based Jack Herer Foundation. Dan Herer, son of the legendary hemp advocate Jack Herer, was born into the hemp movement. Today, Dan carries on his late father’s legacy yet on his own terms and in his own way. If Jack Herer could be called a “warrior” and “activist” for the movement, which he was, Dan carries the family torch in hemp advocacy in the role of an “educator” and “influencer.”
