The Role of Evidence in the US Response to the Opioid Crisis.

The National Institutes of Health is investing hundreds of millions of dollars into new research on opioids. As these studies yield insights and results, their results will have to change policy and practice before they can bend the curve of the epidemic. However, the United States does not have a strong track record of translating evidence on drug policy into action. Three reasons for the translation gap are the historical legacy of drugs in the United States, vested interests, and politics. Researchers can become engaged in policy and political processes to strengthen the US response.
