Addict or pseudoaddict, the solution is the same. Give them a supervised dose as necessary and provide support and encouragement for them to stop if they wish. Anything else and the patient will turn to the black market. It's that simple. You want to stop people dying, provide them with opiates so they don't get fentanyl laced garbage from some street dealer. Anything else is, frankly, just torturing the patient, often in the name of morality when this is not at all a moral issue. One day people will realize this. Until then, addicts will die by the thousands. Some places have already realized this (Portugal, Switzerland, Vancouver BC, and even the US before the war on drugs started early last century).
