Jeff Warren is a Toronto-based writer and radio broadcaster, author of the just-published The Head Trip: Adventures on the Wheel of Consciousness (Random House), an action-packed all-natural psychonaut travelogue through 12 different states of waking, sleeping and dreaming consciousness. The book has been variously described by enthusiastic reviewers as "mind-blowing," "ground-breaking," "deeply stimulating," "hilarious," "exhilarating," and, by the author's mother, as "very interesting though best to read in the morning."

For more information on different states of consciousness, longer reviews of the book, and to find out why the UK's Independent says once you've read The Head Trip you will "never look at waking, sleeping or dreaming the same way again," check out Jeff's website at www.headtrip.ca.
