LOS ANGELES – Lindsay Lohan's move from the Betty Ford Clinic to Cliffside Malibu late Wednesday has been in the works since a visitor of a fellow patient brought a prohibited substance into the facility and distributed it to several girls, multiple sources tell FOX411's Pop Tarts Column.
But Lohan, one insider insisted, did not partake.
“She heard what was going on and was really upset by it and wanted to get out,” the source said. “She’s been doing really well detoxing and didn’t want to be around the temptation of more drugs… Lindsay also wanted to be at a place where she would receive more one-on-one treatment time.”
We’re told the drug brought in was Oxycontin.
Another mom, whose daughter was at Betty Ford at the same time as Lohan, told us she had to transfer her 20-something daughter to another facility as she was one of several girls given a drug, which she could not confirm was Oxycontin.
“She was afraid of a relapse," the upset mother said.. "Some of those who took it have now left voluntarily."
We’re told that getting banned substances in rehab facilities is generally not that difficult as visitors are not rigorously checked.
“I just check my phone and go in,” another insider said.
A rep for Betty Ford declined to comment on the alleged drug outbreak in the facility, but said that the only window of time that non-staff members of non-patients are allowed inside is Sunday afternoons during family visiting time, and that they are not searched for potentially banned substances.
We’re also told that while there is no evidence Lohan took banned substances, she was by no means perfectly behaved and having her there became “problematic” for them too as she “couldn’t follow the rules.”
A source close to the actress denied any problems, and said that her team had received no such indication or report that she had stepped out of line in any way, and that she left Betty Ford as she simply needed a change in the course of her treatment.
“Betty Ford is 30 days and it starts getting repetitive,” said the source.
However, an admissions representative at the California facility insisted that they “have a 30, 60 and 90 day program.”
“Most do the 90 day program, some stay a few days under or over those time frames they have prices for,” said the rep.
Betty Ford also lists information regarding the 90-day program on its official website, “for persons addicted to alcohol and/or other drugs, which lasts for three months.”
In March, Lohan pled no contest to misdemeanor charges stemming from the June 2012 car accident; reckless driving and providing false information to a police officer. She was sentenced to 90 days in a lock down rehabilitation center, 30 days of community service, and 18 months of mandated psychotherapy.
So why would Lohan be doing a monthly program if she was ordered to rehab for three months?
“There was never any ‘enrollment process’ or specific treatment plan. It was just that it was repetitive after about 2 weeks,” the insider explained.
Lohan’s attorney Shawn Holley, as well as the Santa Monica District Attorney’s office did not respond to a request for comment.
