{"chart":{"slug":"nih-opioid-research-funding","title":"How much does NIH spend on opioid research?","takeaway":"NIH funded $825 million of opioid research in fiscal 2025. The category began in fiscal 2018, when NIH launched its HEAL Initiative on addiction and pain partway through the year ($317 million); the most in a year was $947 million, in fiscal 2023. These are totals of the projects listed in RePORTER, so they differ somewhat from NIH's published category estimates.","topic":"Medical research","chart_type":"line","ranking":false,"x_label":"Fiscal year","y_label":"NIH funding (dollars)","unit":"dollars","points_count":8,"source":{"name":"NIH RePORTER (National Institutes of Health), Research, Condition, and Disease Categorization (RCDC)","url":"https://report.nih.gov/funding/categorical-spending"},"license":{"name":"Public domain (U.S. government work)","url":"https://www.usa.gov/government-copyright"},"data_as_of":"2025-09-30","updated_at":"2026-10-17T18:50:41.518Z","url":"https://chart.ly/charts/nih-opioid-research-funding","api_url":"https://chart.ly/api/v1/charts/nih-opioid-research-funding","csv_url":"https://chart.ly/charts/nih-opioid-research-funding/data.csv","image_url":"https://chart.ly/charts/nih-opioid-research-funding/image.png","embed_url":"https://chart.ly/charts/nih-opioid-research-funding/embed","credit":"NIH RePORTER (National Institutes of Health), Research, Condition, and Disease Categorization (RCDC), via Chartly (https://chart.ly/charts/nih-opioid-research-funding)","credit_html":"NIH RePORTER (National Institutes of Health), Research, Condition, and Disease Categorization (RCDC), via \u003ca href=\"https://chart.ly/charts/nih-opioid-research-funding\"\u003eChartly\u003c/a\u003e","average_label":null,"zero_axis":true,"data":[{"label":"2018","value":316862739},{"label":"2019","value":940301078},{"label":"2020","value":775741473},{"label":"2021","value":892605619},{"label":"2022","value":917372855},{"label":"2023","value":946927308},{"label":"2024","value":878541223},{"label":"2025","value":824934646}],"annotations":[]},"docs":"https://chart.ly/developers","terms":"Free to use with credit: wherever you show or quote a chart's data, name Chartly with a link to that chart's url (each chart's credit line does both) and credit its source as its license asks.","credit":"NIH RePORTER (National Institutes of Health), Research, Condition, and Disease Categorization (RCDC), via Chartly (https://chart.ly/charts/nih-opioid-research-funding)"}
