Amanda Bynes' mom is speaking out about her daughter now that she is out of treatment and starting anew.

Lynn Bynes told E! News Wednesday, April 9, that smoking weed caused her daughter's peculiar behavior. "[Amanda] is very sorry for all the hurtful tweets, statements and actions that occurred while she was under the influence of marijuana," she said.

Previously, Tamar Arminak, Amanda Bynes' lawyer, spoke with People magazine to quash some rumors that had been floating around about the former Nickelodeon star. He stated the 28-year-old does not have schizophrenia and does not have an issue with drugs.

"Amanda currently is on zero medication," Arminak said. "She's devoted to living her life as healthy as possible. She's never had a history of abusing alcohol or hard drugs, and she's proud to say she's been marijuana-free for the past nine months."

In March, Lynn Bynes told People that her daughter is "doing extremely well" and has enrolled in classes at the Fashion Institute of Design & Merchandising in Los Angeles.

The "Easy A" star entered treatment last year after a series of odd incidents. She moved to a rehab facility in Malibu and then moved in with her parents upon completion in December.
