A terminal cancer patient shouldn´t have to have hold backs. It not like you have to worry about your health and future. I get why lsd could be dangerous, but at that point it doesn't really matter. I dont see why you woudnt grant that as a final wish.
I know I would want to. I am curious as is, but I find it to scary to try. I heard that it was possible to get small flash trips after you did it.
