I'm an author and independent science writer with a B.S in science journalism from the University of Maryland-College Park (cum laude, 1987). My latest book, which Skyhorse Publishing-NY released in 2020, is HEALING WITH CANNABIS (The Evolution of the Endocannabinoid System and How Cannabinoids Help Relieve PTSD, Pain, MS, Anxiety, and More). My first book was TRIPS: How Hallucinogens Work in Your Brain (1998, Seven Stories Press NY). Between books I wrote documentary scripts for the Discovery Channel (with Cronkite Ward & Co.), then worked as a science writer for the State Department (2004-2010) and the Department of Defense (2010-2017). In 2017 I retired from public service and started writing Healing with Cannabis. Now I'm researching a next book on psychedelic medicine.
