My book, The Little Black Book of Marijuana: The Essential Guide to the World of Cannabis is coming out in August.
As listed in the current catalog of Peter Pauper Press:
This concise guide to cannabis provides the essentials of cultivating, using, and cooking with weed; identifying the many varieties of pot; and understanding legal and health issues. This Little Black Book also delves into pot culture and history, from Herodotus to the hippies, from the rise of the medical marijuana movement to decriminalization. Includes full-color photographs of marijuana varieties. Steve Elliott is a journalist and editor of the Village Voice Media blog Toke of the Town: Cannabis Culture News and Views.
What I have to add to that is that, given the size constraint of 20,000 words, I packed in as much cannabis lore as I possibly could! And had a great time doing it.
You can pre-order The Little Black Book of Marijuana at Amazon, Borders, Barnes and Noble, and just about every major retailer, as well as at your local independent bookstore.
