Why is it taboo to employ opioids to induce psychic analgesia, yet commonplace therapy for acute/chronic phyisical pain? Personal thoughts/ideas?

Controversial. The most effective analgesics currently available are the opioids. For many years, they have been the mainstay of drug treatment to control chronic cancer pain. Their efficacy in acute pain such as postoperative pain is also well established. However, the use of opioids to control chronic nonmalignant painis fairly recent and is a complex and controversial issue.
