Alright, I'm going throw things a different direction just for argument's sake: Sure, you could slap a Butran's patch on him and set him on cruise control. Easy...
Or, (if you have the right resources), you could walk INTO the fire: Wrap him---tee him up with psych/mental health for assessment and treatment of his depression; say, "okay we can do some short-acting full mu agonist as a TRIAL of therapy (but never oxy) within CDC guidelines but you're eventually coming off it, AND you got to stop smoking the Tijuana Ditch Weed. Maybe some hemp-based CBD, but I'm going to pee test you within permitted limits of insurance LCD's for monitoring adherence and abstinence and if you keep f*cking up you're out of here. You're going to meet with our addiction counselor and do the CBT-based work book on pain and adaptive coping. You're going to read this book and watch these videos by Jordon Peterson on 12 Rules for Life. You're going to get hooked up with a peer group (go to church or volunteer), start keeping an exercise diary (which we will review every visit), etc. In short, you're going to take an active road to recovery and rehabilitation from your chronic pain."
Then, you have to have the fortitude to actually follow through. You, THE DOCTOR needs to SHOW UP for this patient. REALLY start tapering when people get more active and engaged. REALLY hold them accountable and INTENSIFY service and treatment when people start back-sliding into eating Doritos and watching Leave it to Beaver re-runs all day. In other words, MANAGE them with one part compassion and one part tough love. It's always been puzzling to me that pain doctors and addiction doctors approach aberrant behavior so differently. Pain doctors say, "One strike and you're out." The addiction doctor says, "I'm going to see you next week and in the mean time you need to do X, Y, Z."
Barriers: Money. No one wants to pay for that $hit. Time. It involves actually sitting, talking, and FEELING with patients. Finally, few of us actually signed up to do that kind of stuff. We're better at sticking long needles into small holes. It pays better and there is an immediate sense of gratification--"hey, look what I did!" In contrast, this patient is going to be a pet-project for years. And, you're going to sink time and opportunity cost into him and go broke in the process!
Other Barriers: These patients will suck the life juice out of your soul and leave you an empty shell of a human being.
