A new study in the International Journal of Drug Policy found that states with legal medical marijuana enjoyed significant reductions in health insurance premiums compared to states where cannabis remained completely illegal.
Analyzing a decade’s worth of private health insurance data from the National Association of Insurance Commissioners, researchers determined that in the years following a state’s implementation of a medical cannabis law, premiums dropped dramatically.
“Although the effect does not begin until seven years post-medical cannabis law implementation,” the authors conclude, “there is a significant and sizable reduction in health insurance premiums” in states that legalize medical marijuana.
“Due to the nature of insurance pooling and community rating,” they add, “these savings are appreciated by cannabis users and non-users alike.”
Researchers were specifically looking at individual private health plans rather than employer-sponsored insurance plans or Medicaid. The study notes that health insurance spending in the U.S. accounts for between 16 percent and 34 percent of the average household budget.
In an attempt to control for other variables, authors focused on states where only medical marijuana was legal, excluding from the analysis states where adult-use legalization was already in effect. States in the control group, meanwhile, included those without medical cannabis or those that had passed but not yet implemented a such a policy
Authors of the research paper were Amanda C. Cook, an economics professor at Bowling Green State University; E. Tice Sirmans, a professor in Illinois State University’s department of finance, insurance and law; and Eastern Michigan University economics professor Amanda Stype.
In March, a separate study determined that states with legal medical marijuana had lower opioid payments to doctors—another indication patients are using cannabis as an alternative to prescription drugs.
On the individual level, a recent study in the International Journal of Drug Policy found that cannabis significantly reduced opioid cravings for people using opioids without a prescription, suggesting that expanding access to legal cannabis could provide more people with a safer substitute.
A study published in January by the American Medical Association (AMA), meanwhile, found that roughly one-in-three chronic pain patients report using cannabis as a treatment option, and most of that group has used cannabis as a substitute for other pain medications, including opioids.
A separate AMA study found an association between state-level medical cannabis legalization and significant decreases in opioid prescriptions and use among certain cancer patients.
The same month, another study found that the pharmaceutical industry takes a serious economic hit after states legalize marijuana—with an average market loss of nearly $10 billion for drugmakers per each legalization event.
