My Lords, I am most grateful to be able to come in at the end of this important short debate. I particularly commend the noble Lord, Lord Field of Birkenhead, for his outstanding and long history as a parliamentarian and, yet again, for his clarity and ethical approach to every subject that he addresses.
I am glad that the Minister has referred to the two studies from the NIHR and simply support the idea that we need to wait for those, although I draw attention to the fact that, in 2018, there was a Cochrane database review, which looked at the 16 double-blind randomised control trials that it could find. It found some support, but it was not terribly strong. One of the difficulties here is that pain is a symptom that occurs in an enormous range of disorders, but the fundamental cause of the pain will be very different in different people. To get a matched population where you can compare one with another is extremely difficult. I hope that the change that NICE is looking to in the evidence that it seeks, where it will also look at evidence in practice, will support the evidence coming through from large patient cohorts who can then be put into broader groups.
The other point about pain is that, as people get multiple pathologies, they often take several other medications as well, which can interfere with the ability to assess them. They are also often elderly. The evidence certainly needs to be accrued. I would say as a clinician that one worry was always whether there would be a leak of cannabis on to the streets. However, in practice, I think that the leakage has gone other way so that it comes from the streets into people’s homes. Clinicians have had to look at this with Nelson’s eye because they do not want to support clinical activity. In a study that I did, while we did not ask patients to tell us specifically where they were getting some things from, when we put together all the different types of alternative therapies
being used by a group of people who were cancer patients, the numbers were huge. This supports many of the comments that have already been made. I am glad that the Government are looking at it and I expect that it will not be too long before we find that the ability to get the medication that is needed is made easier. I worry that it may be too late for some patients, but we are getting there.
