Opioid Watch is a web-based resource that provides original, independent, nonprofit news, information, and comment about the opioid crisis. It consists of both a website and a free weekly newsletter. The newsletter culls and synthesizes the most important and interesting epidemic-related news from around the Web, including developments in treatment, recovery, regulation, legislation, litigation, and research. Opioid Watch is the first project of The Opioid Research Institute, a nonprofit formed in early 2018 with funding from the Joseph H. Kanter foundations. The Kanter foundations have long been devoted to improving the dissemination of information to patients and providers about “what really works” in healthcare. Recognizing the unprecedented gravity of the public health challenge posed by the opioid epidemic, Joseph Kanter, now 94, his wife, Nancy, and son Harry decided to enlist the foundations’ resources in the war on this scourge.
