To the Editor As a Taiwanese physician specializing in addiction medicine, I read with great interest the recent Viewpoint that discussed the complex ethical and legal issues surrounding treating opioid use disorder (OUD) for incarcerated patients in the US. While the situation in the US is concerning, OUD treatment options in prisons in Taiwan are even more limited. In Taiwan, medications such as buprenorphine, methadone, and naltrexone are not allowed in prisons, leaving incarcerated individuals with OUD to experience a range of distressing withdrawal symptoms, including severe nausea, vomiting, shaking, cold sweats, muscle pain, anxiety, and depression. Moreover, in my view as a physician, it is a human rights abuse to withhold necessary treatments that could alleviate these distressing symptoms and improve health outcomes.
