(CNN) - States that have legalized marijuana for managing chronic pain have significantly fewer deaths from prescription painkiller overdoses each year, according to a new study published Monday in JAMA Internal Medicine.
Researchers looked at medical marijuana laws and death certificate data in all 50 states between 1999 and 2010. During that time, just 13 states had medical marijuana laws in place.
"We found there was about a 25% lower rate of prescription painkiller overdose deaths on average after implementation of a medical marijuana law," lead study author Dr. Marcus Bachhuber said.
(CNN) - Do airline passengers have the right to recline?
That simmering debate among fliers escalated Sunday aboard a United Airlines flight that was diverted after two passengers argued over the use of a device that blocks reclining.
A Knee Defender, a gadget that "helps you stop reclining seats on airplanes so your knees won't have to," was at the root of the disturbance.
United Flight 1462 from Newark to Denver was forced to divert to Chicago's O'Hare airport, according to United Airlines. The airline said that it does not allow the use of the recline-blocking device on its aircraft.
A federal law enforcement source, speaking on background, said the incident involved a male and a female passenger, both 48 years old.
