States that have legalized medical marijuana have seen more opioid overdose deaths, according to a new study reported on by Vox — the opposite of what a 2014 study found.

The state of play: The previous study suggested that when people could use cannabis to treat pain instead of opioids, it led to less overdoses. It was embraced by some state lawmakers. However, the researchers who conducted the latest study say that there's probably no relationship between state marijuana laws and opioid deaths.

The Transportation Security Administration is now allowing passengers to bring Epidiolex, an FDA-approved marijuana-based drug, and some forms of cannabidiol (CBD) oil onboard aircraft.

Details: On Sunday, the TSA updated its "What Can I bring?" list, having learned of Epidiolex, which is used to treat seizures in children with epilepsy. "[A]s long as it is produced within the regulations defined by the law," some CBD oils are acceptable in checked and carry-on luggage. That does not include cannabis-infused products and CBD oils with THC, the psychoactive chemical that makes people feel high. The TSA will refer all questionable products to law enforcement.
