As you all know by now, I am concerned with the side effects of cannabis and am still reading on the scientific question of potential harm of marijuana. My objective is to separate fact from fiction. Too much of what is available to readers is opinion and prejudiced. I am finding some very good research, especially on the potential use of cannabis as medicine, which I intend to review here. In the meantime, I wanted to let you know about a cool video I came across. It is put out by National Geographic and was recently on TV. It is called, "Drugged: High on Marijuana" and reviews current research combined with interviews of pot heads. I am attaching a brief video clip on how marijuana works. I found the graphics inside of the human body especially interesting. Please let me know what you think.
