Effects of Intentionally Enhanced Chocolate on Mood has been published in the Elsevier journal Explore: The Journal of Science and Healing, Volume 3, Issue 5, Pages 433-546 (September 2007).

You can download the pdf for free by going to http://www.explorejournal.com/and clicking on "current issue" or "past issues," depending on when you read this post. The issue to look for is September/October 2007.
I plan to continue a line of research focusing on the apparent intentional effects reported in that paper, across a wide variety of substances.
