While the comic revealed to fans that he's been sober for the past seven months, RadarOnline.com has learned he still has a long road ahead of him.
According to a court insider, it will take Lange over two years to graduate from the drug court program in New Jersey's Hudson County.
"There is no way to know what will happen with the case of anyone in drug court," the insider told Radar. "It depends on how they do in recovery. It takes participants about three years to graduate from drug court."
According to the New Jersey courts website, “the mission of the drug court program is to assist defendants in overcoming alcohol and other drug dependencies while resolving related criminal charges.”
Participants must undergo intense recovery programs and drug testing under “intensive supervision."
If Lange breaks any terms of his probation, he could be forced to check into another treatment facility, or worse for him, jail.
As Radar previously reported, Lange was arrested back in May after court officials told Radar he "was non-compliant" with the rule of the drug court program.
“All the stories gave the impression he was doing great, but that is not the case,” the official said at the time.
But fans are relieved to see him looking healthier than ever.
In an Instagram post from, Lange wrote: "Great to be home! 7 months 14 days sober but one day at a time. Lots of new stories to tell."
His current legal woes stem from an initial 2017 arrest for cocaine and heroin possession. In June 2018, he was sentenced to four years of probation in the case, with the assurance he would stay out of prison if he kept his nose clean.
Unfortunately, he relapsed multiple times, so he was transferred to drug court.
