I’m not a medical doctor, so correct me if I’m wrong: opioid and drug tolerance is nowhere mentioned or only once in the article, but seems one of the reasons behind this pseudo addiction behaviour in several described cases, no? Another question that comes to my mind is: if uncertain or under circumstantial evidence, would it be morally more acceptable to point to someone’s addiction at the risk of letting that person really suffer?
