I live in california and in my youth was was known to smoke pot (unfortunately lots of cigs too)

I saw this report and I am curious as to the reaction... Do we like this? What do we think about this ? Medical Pot is available to me - is it valuable? Worth a shot?

I know this source isn't AMA worthy, but I have seen it published on more reputable sites.
