Issues with granny crows list

I have been checking out the links there on the stickey for her list, and it appears as though much if not most of the links I clicked point to the negative aspects of MMJ. For example, there are only 2 entries under addiction/withdrawal, and both are a link to the same study which shows MMJ is as addictive as cigarettes if not worse.


Can someone please provide sone links to research that shows MMJ is less addictive than cigarettes, or that the withdrawal isn't as bad?
