Kelly Osbourne says her first rehab experience was ‘university on how to be a better drug addict’

Kelly Osbourne says she learned “so many tricks” while she was in rehab to continue her drug habits after she left.

“First rehab I went to was, like, university on how to be a better drug addict,” she revealed in the new doc, “TMZ Investigates: Matthew Perry & the Secret Celebrity Drug Ring,” which premiered Monday on Fox.

Osbourne, who struggled with addiction for years, added that she learned “so many things that I never even thought of from my fellow addicts that were in there.”

The former reality star claimed many people threatened to leave rehab if they didn’t get the drugs, like Ambien or Valium, they wanted and were often “given whatever it is they’ve asked for.”

The 39-year-old then alleged that several rehab facilities attempt to exploit recovering addicts in an effort to get them back into their programs.

“They’ll sit outside of AA meetings [Alcoholics Anonymous] looking for weak and vulnerable people that they encourage to go and relapse so that they can then pick you up again,” Osbourne claimed in the documentary.

When TMZ founder Harvey Levin called that allegation “hard to believe,” she swore “on everything” that her claim was “true.”

Elsewhere during the doc, the former “Fashion Police” host shared that doctors would prescribe her various opioids as a teenager without questioning her.

“It started off with Vicodin and ended up with OxyContin,” she said. “Which is a lot stronger and very dangerous.”

She recalled telling the doctors that she “was in pain” and that they “just wrote me a prescription.”

She also claimed that the doctors wouldn’t call her parents, Ozzy and Sharon Osbourne, about their daughter’s prescriptions.

The mother of one began her sobriety journey in 2017. In 2021, she appeared on “Red Table Talk” and revealed that her substance abuse issues began at age 13, when she was prescribed opioids after tonsillitis surgery.

Kelly relapsed in 2021 before getting sober again. She took to Instagram in May 2022 to celebrate one year of sobriety ahead of welcoming her son, Sidney.

In the shocking doc, Kelly even recalled filling her own prescriptions without her parents during her teens.

“I’d go with an older friend,” Kelly shared. “In retrospect when you say this now it’s so crazy because there’s now way a 13-year-old would be able to go into a pharmacy and just pick up this kind of medication without having a parental figure there in some way.”

Kelly has been open about her struggles with drugs and alcohol over the years, however, these days she is focused on raising her 1-year-old son.

Just last month, the proud mom shared a video of her trip to the zoo with Sidney. “Partying with the animals at the zoo!” she captioned the sweet post.
