“Lyle is a long-time professor of plant medicine, and is well known worldwide. I often ask people in foreign countries if they know of him, and often they do. Lyle brought me into U Mass, and has been gracious and kind. He also has done heroic work trying to get DEA off their butts to allow U Mass to cultivate cannabis. ” – Chris Kilham, Medicine Hunter
