Can cannibas oil be bought over the counter or in health shops in Ireland. My father has bone marrow cancer (7 fractures in his back)which is one of the most painful cancers you can get. They even broke one of his ribs putting back brace on in hospital. Methadone, morphine and everything else isn't working and eventually kidney failure is the next thing from the amount of pain medication taking its toll but without the meds he wouldn't be able to live.
