Big Medicine needs Big Money. The Cancer folks figure there's more money in this than cannabis could ever bring in. If they did do detailed studies on how well cannabis can improve health then they might lose that big fat financial gravy train. Any major government studies will just aim to disprove cannabis as a viable medical product or show how "unsafe" it is and we need to protect "the children" -(or something like that). Thank heavens I'm no longer a nurse-couldn't stand that crap.
