I have seen this beneficial effect first hand and was amazed so I have no objection to medicinal use. In fact why not just legalize it and tax it.
Amazing really is the word for it. It is such a shame that the "stoners" who use it for fun have ruined it for the people who could benefit it from it.
I don't even want to describe the things I have had to go through to get it -- dealing with shady characters and putting my friends at risk to help me get it. Making it legal and taxing it would make it easier for the stoners and I would really not want that. But I just don't see any reason they can't just make it available to the cancer doctors. Or better yet, extract the actual substance (THC) as a tincture, put it in a vaporizer like an E-Cig, and give it to the cancer patients.
