My opinion is that it's not the best idea to try to find and associate single universal truths (definitions) for these terms. It can even be destructive and dangerous in my view because, say, someone who is not compatible with my approach might perceive theirs as failure or an attack on their self worth. So I tend to go with terms and definitions only as far as "sobriety", meaning giving up substance abuse and in most cases, specific substance use altogether. Now what comes beyond that and how we call it is most often very personal and subjective. Probably one thing that's true is that we all seek happiness and a better life.
