MLB, Union Agree To Test For Opioids; Pot No Longer Banned

The MLB and Players Association announced changes to their drug policy, removing marijuana from the list of banned substances and treating it similarly to alcohol. The policy now includes testing for opioids, cocaine, fentanyl, and synthetic THC. Players testing positive will be referred to a treatment board. Suspensions for marijuana use in the minor leagues will be canceled. The new rules are expected to take effect at the start of the 2020 spring training.
