The patient is an addict. His doctor is an addict, too. Over the last decade, both men hit their own versions of rock bottom. For the patient, it was the concrete floor of a jail where he writhed in withdrawal. For the doctor, it was the food stamp office where, his career as a child psychiatrist in tatters, he ashamedly sought help. Then they both found buprenorphine, the patient as a user, the doctor as a prescriber. And because of that drug, an opioid used to treat opioid addiction, they both rebounded, even thrived.
