simple. There should never be a daily dose of BZD. That is by definition chemical coping. Anxious patients should be treated with SSRI, may buspirone, psychotherapy etc. I can see a role for 1-3 rescues doses a month of a BZD for extreme situations, but that is it, and most anxious patients don't even need that.
But any patient who thinks they "need" QD, BID, TID dose of BZD is a chemical coper and should not be be prescribed concurrent opioids even if their entire body is fused. They get no more than one daily type of pill that can suppress their breathing, not two kinds which multiple their risk.
Life is all about priorities and compromise, you shouldn't compromise your license, because such patients can't prioritize their needs. There is no role for daily opioids and daily BZD except in palliative care for terminal patients.
