Jones tested positive for a steroid prior to his July 29 title fight against Cormier, which he won in a third-round TKO.
The second sample from Jones's failed test also came back positive on Tuesday and the Cormier fight was subsequently ruled a "no contest" by the California State Athletic Commission.
Jones, 30, was previously banned for a year after failing a doping test in the run-up to a title fight against Cormier in July, 2016.
He was originally stripped of the title in 2015 following a hit-and-run incident.
As a repeat offender, he faces a suspension of up to four years.
