Lung Cancer is no joke! Rick Simpsons oil is what you need her on...NOW! It saved my life when chemo couldn't and it is even helping with the issues caused by the chemo. At her age with lung cancer, you need to get bigger doses into her ASAP. Vaping, eating edibles and juicing all are good but the concentrates is what is the cure. I now crush my bud into powder and use 00 capsules. One drop of oil and the rest powder. I was taking a gram of oil for over two years, now I still take a dose but generally its for maintenance purposes only. Tell your Gramma that ther will be no effects...buzz, wasted feeling once she has gotten it in her system...Trust me when I say...I don't get High anymore! Hope the best and PM me if you need anything...JAS ...................P.S. ilexes and tinctures also work better than edibles and can be concentrated down for a potent mix.
