NORML:

Specific parts of NORML worth noting:
http://www.norml.org/index.cfm?Group_ID=3382
http://www.norml.org/index.cfm?Group_ID=3381
http://www.norml.org/index.cfm?Group_ID=4428

Those are only a couple pages but I'd recommend looking at the entire "Personal Use" section as well as "Medical Use" I found those sections the most helpful. But you can find droves of info all over the NORML site, as well as really good links.
