LOS ANGELES , California ( CNN ) -- Doctors gave Anna Nicole Smith a long list of dangerous drugs over the three years before her death , including while she was pregnant , according to sworn statements by investigators from state agencies . Dosages prescribed to Anna Nicole Smith were `` dangerously high , '' a drug expert says in an affidavit . Two doctors charged in connection with Smith 's death allegedly also crossed professional lines by having personal relationships with their patient , the court documents released Tuesday said . Smith died in a Hollywood , Florida , hotel on February 8 , 2007 , of what was later ruled to be `` acute combined drug intoxication . '' One affidavit quoted a pharmacist who refused to fill a prescription written for Smith as saying he warned one doctor he would not give her the drug `` unless you want your picture on the front page of the National Enquirer . '' One investigator described the former Playboy model and reality show TV star as a `` drug seeker . '' Her boyfriend , Howard K. Stern , and two doctors -- Dr. Khristine Eroshevich and Dr. Sandeep Kapoor -- were charged with several felonies , including conspiring to furnish controlled substances , unlawfully prescribing a controlled substance and obtaining fraudulent prescriptions from June 2004 through January 2007 . All three defendants entered not-guilty pleas in May . A preliminary hearing is set for next month in the case . Smith , whose real name was Vickie Lynn Marshall , `` was given drugs in excessive amounts , '' according to a medical expert consulted and quoted by a state medical board investigator . Dr. Jill Klessig also told an investigator that `` in addition to the prescribing issues , there appears to have been a personal relationship '' between Smith and the two doctors that crossed the boundaries of professionalism . The affidavit references a video clip of Kapoor `` kissing and snuggling '' with Smith `` in a reclined position in a nightclub setting . '' Eroshevich traveled to the Bahamas to visit Smith and was with her for four days in Hollywood , Florida , four days before her death , an investigator said in an affidavit . The doctor personally visited a Burbank , California , pharmacy in September 2006 to get a sleep aid -- chloral hydrate -- for Smith to use in the Bahamas . It was just four days after Smith gave birth to a daughter in Nassau . `` I would n't give her chloral hydrate unless you want your picture on the front page of the National Enquirer , '' pharmacist Steve Mazlin told Eroshevich , according to the affidavit . The affidavit from Jon Genens , a senior investigator with the California medical board , detailed dozens of prescriptions written for Smith -- under several aliases -- for a long list of narcotics and sleep aids . Genens said even during the time she was pregnant -- starting in January 2006 -- Kapoor prescribed an average of 10 tablets of Methadone per day for Smith . He noted that Kapoor lowered the dosage in the last three months of her pregnancy . The volume of dangerous drugs being ordered by doctors spurred the chief pharmacist at the store where most of the prescriptions were filled to call a drug expert for advice in late 2006 , according to a sworn statement by California Department of Justice Special Agent Jennifer Doss . Dr. Greg Thompson told Doss he recalled the dosages were `` dangerously high . '' `` Dr. Thompson stated they might work for a drug addict under supervised care , or with a dying cancer patient in a hospital , or 'if you were going to kill someone , ' `` Doss said . Thompson told Doss he later `` admonished Dr. Eroshevich '' about the drugs she was requesting for Smith . `` Dr. Thompson stated Dr. Eroshevich was obviously not familiar with a lot of medications she was prescribing for ... Smith , '' Doss said in her affidavit . The Doss affidavit said the doctor used Smith 's boyfriend as a cover to get the prescriptions filled . `` Of the 12 medications found in Anna Nicole Smith 's hotel room at the time of her death , seven medications were prescribed the name of Howard K. Stearn [ believed to be Howard K. Stern ] by Dr. Eroshevich , '' Agent Doss said . The drugs were apparently personally delivered to Smith in the Bahamas and Florida by her doctor , Doss said . `` It is reasonable to believe that Dr. Eroshevich provided Anna Nicole Smith prescription medications and controlled substances by transporting them from California to Nassau , Bahamas with her on her travels to visit Anna Nicole Smith , '' Doss said .
