Requirements aimed at curbing Tennessee’s opioid epidemic are among more than 150 new laws that kick in Sunday. Many laws take effect on July 1 each year, when a new state budget year begins, and some of the highest profile ones this time around are part of Republican Gov. Bill Haslam’s “TN Together” opioid plan. Tennessee will begin limiting initial opioid prescriptions to a three-day supply, with exceptions for major surgical procedures, cancer and hospice treatment, sickle cell disease and treatment in certain licensed facilities. With the three-day initial supply restriction, Haslam’s office says, “Tennessee will have one of the most strict and aggressive opioid policies in the nation.” The Tennessee Medical Association, the state’s doctor lobbying group, has said it’s still concerned about unintended consequences for patients who may have more difficulty accessing effective pain management because of the law. Among other components, the opioid laws will offer incentives to get offenders to complete substance use treatment programs in prison and make it a second degree murder charge to deal fentanyl and similar dangerous substances when it causes a death.
