Fewer Pain Pill Overdoses In States With Legal Medical Marijuana
-
The study reveals that states with legal medical marijuana had a 24.8 percent lower annual average painkiller overdose death rate than states without those laws. It also shows that in the years following the legalization of medical cannabis, the association was stronger over time -- in the first year of legalizing medical cannabis, painkiller overdose deaths were nearly 20 percent lower in states with the laws than without, and nearly 34 percent lower five years later, on average.
"It's important to note that this isn't a 25% decrease in rates, but a 25% lower rate than was expected," Dr. Marcus Bachhuber, the study's lead author and a Robert Wood Johnson Scholar at the Perelman School of Medicine at the University of Pennsylvania, told The Huffington Post.
About 60 percent of all opioid overdose deaths occur in patients who have legitimate prescriptions for the drugs, according to the CDC. In 2009, overdoses from prescription pain relievers resulted in the deaths of more than 15,000 people in the U.S.
"The proportion of people receiving prescription opioids to treat pain has almost doubled in the past 10 years," Bachhuber said. "Chronic or severe pain is the main reason for which people report taking medical marijuana in states that make this information public."
