Chris Cornell's former doctor is denying he had anything to do with the rocker's tragic death, and claims Cornell was well advised about the dangers of the anti-anxiety medication he was prescribed.

According to documents obtained by The Blast, Dr. Robert Koblin is responding to the wrongful death lawsuit filed by Cornell's widow, Vicky. Koblin is denying all the allegations that he overprescribed medications to the "Soundgarden" star before his death, even though he was an "addiction-prone individual."

Koblin says Cornell was "well aware" of the risks with taking the anti-anxiety meds, and argues he's covered by a malpractice law that protects doctors when a death occurs as as result of a patient's ongoing disease or condition.

The doctor also claims Cornell asked "not to be informed" of all the risks associated with taking anti-anxiety medication, and that he did everything in his professional capacity to help the star.

Last November, Cornell's widow sued the doctor claiming he prescribed the singer over 940 dozes of Lorazepam (Ativan) in the last 20-months of his life, and believes it contributed to his suicide.

Dr. Koblin believes he followed procedure to the best of his ability, and is asking that the wrongful death suit be dismissed.
