Remember when Amanda Bynes was at her wackiest last year - taking selfies in gyms, throwing vases out of windows, telling Drake to murder her vajayjay, all that good stuff?

At the time, it looked increasingly like the starlet was suffering from untreated mental problems. But according to Mama Bynes, pot, and nothing but pot, was to blame for all that craziness.

"Amanda has no mental illness whatsoever," Lynn Bynes told E! News. "She has never been diagnosed as schizophrenic or bipolar," adding that Amanda "is very sorry for all the hurtful tweets, statements and actions that occurred while she was under the influence of marijuana."

Lynn's statements are being backed up by the family attorney Tamar Arminak, who says Amanda is taking no medication at all right now.

"There has been much speculation about Amanda's medical condition," he said. "She has remained silent because she believed it was best to keep her mental health diagnosis private. However, she asked me to dispel certain rumors. For the record, Amanda does not have schizophrenia, nor has she ever been diagnosed with it. Amanda currently is on zero medication. 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."

What do you guys think - does marijuana REALLY make people behave like that?
