Athens, GA — The enactment of statewide medicinal cannabis laws is associated with a quantifiable decline in the use of traditional prescription drugs, according to data published in the July edition of the scientific journal Health Affairs.
Investigators at the University of Georgia assessed the relationship between medical marijuana legalization laws and physicians’ prescribing patterns in 17 states over a three-year period (2010 to 2013). Specifically, researchers assessed patients’ consumption of and spending on prescription drugs approved under Medicare Part D in nine domains: anxiety, depression, glaucoma, nausea, pain, psychosis, seizures, sleep disorders, and spasticity.
Authors reported that prescription drug use fell significantly in seven of the nine domains assessed.
“Generally, we found that when a medical marijuana law went into effect, prescribing for FDA-approved prescription drugs under Medicare Part D fell substantially,” investigators reported. “Ultimately, we estimated that nationally the Medicare program and its enrollers spent around $165.2 million less in 2013 as a result of changed prescribing behaviors induced by … jurisdictions that had legalized medical marijuana.”
Investigators estimated that prescription drug savings would total more than $468 million annually were cannabis therapy to be accessible in all 50 states.
They concluded, “Our findings and existing clinical literature imply that patients respond to medical marijuana legislation as if there are clinical benefits to the drug, which adds to the growing body of evidence suggesting that the Schedule I status of marijuana is outdated.”
Survey data compiled from medical marijuana patients reports that subjects often reduce their use prescription drug therapies, particularly opioids, when they have legal access to cannabis. According to a 2015 RAND Corporation study, opiate-related abuse and mortality is lower in jurisdictions that permit medical cannabis access as compared to those that outlaw the plant.
