Entertainment TV Everything Pete Davidson Has Said About Sobriety and Managing Borderline Personality Disorder Just over a year after announcing his sobriety, Pete Davidson revealed he's back to drinking and smoking following his diagnosis of borderline personality disorder By Jodi Guglielmi Jodi Guglielmi Instagram Twitter Writer-Reporter, PEOPLE People Editorial Guidelines Published on June 6, 2018 04:52 PM Share Tweet Pin Email Pete Davidson says marijuana has helped him manage his health issues. Just over a year after announcing his sobriety, Davidson revealed he’s back to drinking and smoking following his diagnosis of borderline personality disorder. “Party’s back on,” he recently said during an interview with Peter Rosenberg on Open Late. “I found out I had a mental disorder. I thought I had a drug problem. It’s a completely different thing.” After going to rehab and remaining sober for several months, the Saturday Night Live star, 24, said he wasn’t feeling the relief he expected, which pushed him to seek further help. “You can be sad and do drugs at the same time, evidently,” he said. “I got sober for three months and I was just like never sadder and everything was just way worse.” Davidson, who is now dating Ariana Grande, joked that he immediately started smoking marijuana again after receiving his diagnosis. “I just rolled a joint and I was back immediately,” he said. The comedian said smoking has “dramatically” helped ease some of his problems with anxiety and treat his Crohn’s disease. Davidson first opened up about his diagnosis in September 2017 during an interview on theWTF with Marc Maron podcast.

Rodriguez/Getty The comedian explained that the symptoms of the disorder were behind his decision to check into a rehabilitation program in December 2016, initially thinking that the mental breakdowns he was experiencing were due to heavy marijuana use. “I’ve been a pothead forever,” Davidson said. “Around October [or] September last year, I started having these mental breakdowns where I would, like, freak out and then not remember what happened after. Blind rage.” Pete Davidson/Instagram He decided to take a break from SNL and start rehab. “I never really did any other drugs, so I was like, ‘I’m gonna try to go to rehab. Maybe that’ll be helpful,’ ” he said. “So I go and I get off weed. They’re like, ‘You might be bipolar,’ and I was like, ‘Okay.’ So they’re like, ‘We’re gonna try you on these meds.’ And then I got out [of rehab], and then I started smoking weed again — and I’m on meds.” Want to keep up on the latest from PEOPLE?

In February 2017, he “just snapped” and had another “really bad” mental breakdown, so he cut out marijuana completely. But Davidson was still struggling and went back to his doctors. “I found out I have BPD, which is borderline personality disorder,” he revealed. “One of my psychiatrists [diagnosed me]. He was always saying before this big meltdown, ‘You’re probably bipolar or borderline, we’re just going to have to figure it out.’ ” “It is working, slowly but surely,” he continued. “I’ve been having a lot of problems. This whole year has been a f—ing nightmare. This has been the worst year of my life, getting diagnosed with this and trying to figure out how to learn with this and live with this.”
