The studies, published Monday in the journal JAMA Internal Medicine, compared opioid prescription patterns in states that have enacted medical cannabis laws with those that have not. One of the studies looked at opioid prescriptions covered by Medicare Part D between 2010 and 2015, while the other looked at opioid prescriptions covered by Medicaid between 2011 and 2016. The researchers found that states that allow the use of cannabis for medical purposes had 2.21 million fewer daily doses of opioids prescribed per year under Medicare Part D, compared with those states without medical cannabis laws. Opioid prescriptions under Medicaid also dropped by 5.88% in states with medical cannabis laws compared with states without such laws, according to the studies.
“This study adds one more brick in the wall in the argument that cannabis clearly has medical applications,” said David Bradford, professor of public administration and policy at the University of Georgia and a lead author of the Medicare study. “And for pain patients in particular, our work adds to the argument that cannabis can be effective.” Medicare Part D, the optional prescription drug benefit plan for those enrolled in Medicare, covers more than 42 million Americans, including those 65 or older. Medicaid provides health coverage to more than 73 million low-income individuals in the US, according to the program’s website. “Medicare and Medicaid publishes this data, and we’re free to use it, and anyone who’s interested can download the data,” Bradford said. “But that means that we don’t know what’s going on with the privately insured and the uninsured population, and for that, I’m afraid the data sets are proprietary and expensive.” ‘This crisis is very real’ The new research comes as the United States remains entangled in the worst
