In the months leading up to Amanda Bynes’ forced hospitalization last July, there was speculation about what was to blame for the former child star’s erratic behavior.
But now, more than four months after she was discharged from her treatment facility, Amanda’s mom, Lynn Bynes, is refuting claims the 28-year-old has been diagnosed with a mental illness—and revealed the shocking cause of her bizarre outbursts.
“Amanda has no mental illness whatsoever. She has never been diagnosed as schizophrenic or bipolar,” attorney Tamar Arminak said on Lynn’s behalf. “She is very sorry for all the hurtful tweets, statements and actions that occurred while she was under the influence of marijuana.”

In May 2013, police officers were called to Amanda’s apartment building after reports of a disturbance. The actress was later accused of throwing a glass bong out of her Midtown, Manhattan, high-rise apartment that allegedly contained evidence of pot.
One of the photographers inside Amanda’s apartment during the party that ultimately led to her arrest told In Touch she had “at least a dozen hand-rolled joints on her” before the party.
“She is constantly smoking weed,” the partygoer told the mag. “I was amazing by how much weed this girl smokes.”
Shortly after the incident, the Easy A actress entered an inpatient facility in Malibu, where it was widely reported she was being treated for a mental illness. Additionally, she spent some time in the psych ward at UCLA Medical Center before returning home in December.
According to Arminak, Amanda has been free of substance—be it prescription medication or marijuana—for nine months.

“Amanda currently is on zero medication,” he said. “She’s devoted to living her live as healthy as possible.”
And so far—it would appear all is going well for the once-troubled star.
She’s currently majoring in fashion design at the Fashion Institute of Design & Merchandising. Not to say it’s all work and no play. Last week, she celebrated her birthday by vacationing with her parents in Cabo San Lucas.
“Thank you everyone for all the birthday wishes,” Amanda tweeted with a picture of her looking happier and healthier than ever in a yellow bikini.
