With stage 1 fibrosis and non alcoholic fatty liver disease would it be better to use (very rarely) edible or inhaled marijuana. It's legal, of course?

By all means. Some of my colleagues will be angry with me, but this is a situation where politics makes good science impossible and thus common sense and common kindness should take over. But what I'd really like to see is have you get high on exercise. This may be what your liver is asking you for, and it could save your life in a few different ways.
