MLB to stop testing minor leaguers for marijuana as part of new policy agreement, report says
MLB and the MLB Players Association are negotiating changes to the drug agreement that would introduce opioid testing. As part of the new drug agreement, MLB would also remove marijuana from the league's list of banned substances for minor-league players, according to The Athletic's Ken Rosenthal. Players on the 40-man roster are not tested for marijuana, but non-40-man roster minor leaguers are, and several are suspended for marijuana use each season. There were 13 such suspensions in 2019.
