Doctors who prescribed a variety of medications to Lindsay Lohan are being investigated by the Medical Board of California.
Michael Lohan's lawyer, Lisa Bloom sent a letter to the California Attorney General back in July, asking for an investigation into "the unscrupulous doctors [who] over prescribe medications ".
The A.G. then referred the matter to the Medical Board, which launched an investigation.
"The Medical Board is investigating and Michael and I are cooperating with them," TMZ.com quoted Bloom as saying.
Prior to entering UCLA, Lindsay had various prescriptions, including Dilaudid, Adderall, Nexium, Zoloft, Trazodone and Ambien.
Later, UCLA determined Lindsay had been misdiagnosed with Attention Deficit Hyperactivity Disorder (ADHD) and prescribed meds she should not have taken.
