Anna Nicole Smith's Former Doctor Claims She Was Not an Addict: 'I Think She Had Bouts of Misuse'

Dr. Sandeep Kapoor has a new book out called "Trust Me, I'm A Doctor."

More than a decade after Anna Nicole Smith died of a drug overdose in a Florida hotel, her doctor is making some surprising claims about the former Playboy playmate.

Following the starlet's February 2007 death, authorities found 1,500 prescription pills in her room at the Seminole Hard Rock Hotel and Casino.

Her doctor, Sandeep Kapoor was later charged with illegally prescribing drugs to the 39-year-old.

But Dr. Kapoor tells Inside Edition that he did not prescribe the 1,500 pills and only recommended methadone, valium and Ativan.

Among the controversial statements in his new book, Trust Me, I’m a Doctor, the Los Angeles physician claims that the beauty was not a drug addict.

“I think she had bouts of misuse; I think abuse and misuse are something confused,” he told Inside Edition.

When she appeared at the 2004 American Music Awards, slurring her words, millions of fans worried she was abusing drugs.

Dr. Kapoor has his doubts.

“She didn’t eat. She had a seizure that day but she didn't want to disappoint, so she went on with it,” he said.

Video of a pregnant and seemingly stoned Smith in clown makeup only bolstered fears that she was addicted to drugs, but Kapoor questions whether she was acting.

“You wonder [if she was high] but then you say was that a stupid prank or some kind of a joke,” he said.

Questions over his relationship with his patient came to light during his criminal trial after photos and video surfaced showing them together during a gay pride parade in West Hollywood.

“It certainly was bad judgement that day. And certainly I probably would not have done it in hindsight,” he said.

But he doesn't feel that he contributed in any way to her death and said he is “absolutely” at peace with his treatment of Smith.

Kapoor claims he actually dropped Smith as a patient a few months before her death because she refused to move back from the Bahamas to Los Angeles.

“I told her if you don’t come back to Los Angeles, I can't continue to treat you or to even offer advice to you,” he recalled. “She said, 'So you're abandoning me at my worst time?' It was very hard.”

Dr. Kapoor believes the 2006 death of Smith’s 20-year-old son, Daniel, led to her own death. He died after overdosing on drugs that Kapoor believes were prescribed to his mother.

“Daniel overdosed on methadone, which was her methadone,” Kapoor said. “That grief and guilt never left her.”

A judge found that Smith was not an addict but rather a person seeking relief from chronic pain.

A jury found Kapoor not guilty on all six counts in 2010.

“It was six not guilties. Six knives pulled out of my back," he said. 

Kapoor still practices medicine in Los Angeles. He says it took more than three years and $1,500,000 in legal fees to finally clear his name.
