Thanks for your reply. It is ridiculous, but then it's all about money and big pharma as usual. The physio knows several patients who also use cannabis, and it works, and recommended it to me...but it's ridiculous that we have to break the law and risk prison just to be able to have a pain free life.
If only medicinal cannabis were to be legalised, it would actually cost the health service less, free up hospital beds and free up doctors waiting rooms. The prescriptions for Nsaids and Opioids costs the government far more, plus they actually exacerbate the condition and pain in the long run (they cause eroding of the cartilage). I'll upvote when I can.
