Don't know of any where local but I do remember there was an elderly lady that suffered with MS, and I think it was Carlisle, that made the news because her landlord was going to evict her for using drugs on his premises. I think I have the gist of the story correct in that this lady, to relieve her pain, discomfort and other MS related neurological symptoms she used to meet up with others in a similar situation and eat cake that had been made with an amount of cannabis in the mixture.
I can't find that particular news story, from many years ago, online but did find this one from 2001 :-
