Yahooka Links to just about everything Marijuana related you could think of. Includes a chat room and a discussion board.
RedMonkey's Ganja Heaven Smoking Etiquette, links, and a chat room (didn't play with the chat room though). The etiquette is awesome though.
Spunky Enterprises Nifty little pot site. Worth checking out.
Hempshoppe.com Hemp accessories (e.g. Necklaces, smoking novelties, etc.).
Hemp Recipes The name says it all. Ranges from appetizers to breakfasts (hemp-nut waffles...yum!)
Burkes Hemp Filtered Premium Ale That's right...they even have hemp beer.
That's about all I can pull up for one day.
Check back regularily to see if there's anything new.
