To a therapist who knows my history in great detail, I told I have taken up a long abandoned pot habit, smoking about a pencil eraser sized bit or two a day. I said it was one of the very few things that reliably helps me feel better. She was not the least concerned and said she knows many people who have far worse habits. And that was the end of that topic. The weight off my mind is a great relief. (I was really afraid of her passing a moral judgement on me, as she is a Christian, and I am atheist.) I think most people are starting to realize this is not really a big deal, far less trouble than the many alternative "bad" habits.
