Within the past decade, prescription drug use has turned into an epidemic with more and more people overdosing.
A new study finds that fewer people in certain states are dying from pills.
Researchers from Johns Hopkins Bloomberg School of Public Health and the Philadelphia Veterans Affairs Medical Center found overdose rates were about 25 percent lower in states where medical marijuana is legal.
Although the reasons aren't 100 percent certain, experts think it's because there are fewer patients taking powerful painkillers and turning to marijuana instead.
However, more research needs to be done to back up the use of medical marijuana.
Right now, 23 states have legalized medical marijuana.
Mark Woodward, with the Oklahoma Bureau of Narcotics, stopped by the studio to talk about the study.
