LOS ANGELES , California ( CNN ) -- Dangerous cocktails of prescription drugs were pumped into Anna Nicole Smith `` almost to the point of stupefaction '' and eventually led to her death , California Attorney General Jerry Brown said Friday . Anna Nicole Smith 's boyfriend Howard K. Stern was among those charged Thursday . Brown called Smith 's longtime partner and attorney Howard K. Stern the `` principal enabler '' in a conspiracy with two doctors for giving the `` known addict '' thousands of prescription pills . Stern and a doctor were jailed on charges of conspiring to furnish drugs before her death in 2007 , authorities said . `` Stern and Dr. Sandeep Kapoor were arrested and later released from a Los Angeles County jail Thursday night after each posted a $ 20,000 bond , a police spokesman said . Dr. Khristine Eroshevich also faces charges and is expected to turn herself in Monday , authorities said . The doctors and Stern devised a plan to use fake names so Smith could be prescribed `` thousands of pills , '' Brown said . Her doctors knew she was addicted and gave her drugs `` excessively , '' Brown said . `` The quantity of the drugs , the variety of the drugs , the combination at any given point and her continuing to use that ; that , to a professional , is clear evidence of addiction , '' Brown said . `` These cocktails of methadone and antidepressants and sleeping pills and Xanax , you put all that into a cocktail , it explodes and can cause death , injury and permanent morbidity and disability , '' he said . Watch Brown speak to the media » . Brown said he hoped the charges send a loud and clear message . `` Doctors do not have a license to pump innocent and often vulnerable people full of dangerous chemicals , '' he said . Smith , 39 , was pronounced dead February 8 , 2007 , after being found unconscious in her hotel room at the Seminole Hard Rock Hotel & Casino near Hollywood , Florida . The former Playboy playmate and reality TV star died from an accidental overdose of prescription drugs , a coroner said . Several prescription medications -- both in Smith 's and Stern 's names -- were found in the room after her death . Officials said prescription and over-the-counter drugs were found in Smith 's system , including three antidepressant or anti-anxiety drugs . Also found in toxicology testing was human growth hormone and chloral hydrate , a sleep medication , officials said . Stern and Kapoor , both 40 , and Eroshevich , 61 , each were charged with eight felonies , including conspiring to furnish controlled substances , unlawfully prescribing a controlled substance and obtaining fraudulent prescriptions from June 2004 to January 2007 -- only weeks before Smith 's death . Kapoor and Eroshevich also were each charged with obtaining a prescription for opiates by `` fraud , deceit or misrepresentation . '' And each was charged with one count of obtaining a prescription for opiates by giving a false name or address , according to the Los Angeles District Attorney 's Office . Smith was buried in the Bahamas on March 2 , 2007 , next to the grave of her son , Daniel , who had died in September 2006 , days after the birth of her daughter , Dannielynn . Brown said his office will aggressively target California doctors who over-prescribe dangerous drugs . `` People think those drug dealers on the street corners are the only threat , '' he said . `` As a matter of fact , people in white smocks and pharmacies and with their medical degrees are a growing threat , and we aim to curtail it and curb it in the best way we can .
