Just some thoughts...I am not a drug user but I will say this, any natural substance which will ease terrible pain and (possibly even) ease the end of life situation I am all in favor of. We cannot know for sure what the coming two years hold, or even beyond but it is possible we survivors will have to make do with whatever we have. Every group should ideally sort out where they draw the line and how to help someone who is suffering or dying.
As I say I am not a drug user but many many years ago I was in a lot of pain in my back, incapacitating. I had five kids to raise. Someone brought some grass 'round and I said I did not use it any more. However I did take one toke, then one more later on and the pain was gone for a couple of days. I didn't rely on it beyond that, but the deal is I can personally say it was an amazing pain reliever. (I don't recommend it for every day but as a survival medical tool.)
