Los Angeles , California ( CNN ) -- Actor Corey Haim was the `` poster child '' for the problem of addicts `` doctor shopping '' for dangerous drugs , California 's top law enforcement official said Tuesday . Investigators found that the former child actor was supplied with prescriptions for five controlled substances by seven doctors in the last 10 weeks of his life , Attorney General Jerry Brown said . `` Corey Haim actually obtained 553 dangerous drugs in just this year , as late as five days before he died , '' Brown told reporters at a news conference in Los Angeles . The drugs included Vicodin , Valium , Soma , Oxycontin and Xanax , Brown said . The coroner has not yet ruled on what killed Haim , 38 , who died last month after collapsing at the Los Angeles apartment he shared with his mother . Toxicology lab results are expected to be available this month for Haim , who battled drug addiction for decades . Haim visited several emergency rooms and urgent care clinics with complaints of an injured shoulder or depression issues , according to Sara Simpson , head of the state task force investigating doctor shopping . Los Angeles County Deputy Coroner Ed Winter revealed last month that Haim obtained drugs using prescriptions written under the names of 20 Los Angeles doctors in the past year . The coroner subpoenaed medical records from those doctors . Haim also obtained at least one prescription of Oxycontin through the use of an illegally obtained prescription pad , Brown said . State agents arrested one person last month in connection with what Brown said was a massive drug ring that obtained and sold the counterfeit doctor 's pads . Although Haim battled drug addiction for decades , his manager said his death came when Haim `` was making major progress '' with a program to wean him from pills . Still , Haim sometimes threatened to find other doctors to prescribe him drugs when his primary physician would n't give him what he wanted , manager Mark Heaslip said Monday . `` I would be the only one who could talk him out of it , '' Heaslip said Monday night . His doctor was providing pills only in one-day supplies in an effort to wean him , Heaslip said . Haim 's primary care doctor would constantly follow up with urgent care centers that he believed were writing prescriptions for Haim , Heaslip said . The doctor later gave the information to investigators , he said . Simpson confirmed to CNN that Haim 's doctor was helping investigators . Haim had a prescription for the muscle relaxer Soma and the narcotic pain reliever Norco filled at a pharmacy February 26 , a source with knowledge of the transaction told CNN . Two days after Haim picked up the drugs , his primary care doctor called the San Fernando Valley pharmacy to ask about the prescriptions , the source said . An autopsy revealed that Haim suffered from pneumonia , an enlarged heart and water in his lungs when he collapsed March 10 , Winter said . Heaslip said he and Haim 's family are convinced his death was not from a drug overdose , but was perhaps a bad reaction to a single pill he took in the hours before his death . The pills , prescribed by an addiction specialist , came with a warning that they should not be taken by someone with a heart condition or flulike symptoms , both of which Haim had , Heaslip said . `` This kid was making major progress , '' Heaslip said . His manager said that if Haim was cheating on his addiction program , he would probably not have admitted it to him since he would have dropped Haim as a client . Haim began his acting career in 1982 , with his first television appearance on the Canadian series `` The Edison Twins . '' His first film role was in the 1984 American movie `` First Born . '' Haim also won rave reviews for his title role in the 1986 film `` Lucas . '' Film critic Roger Ebert said of him at the time , `` If he continues to act this well , he will never become a half-forgotten child star , but will continue to grow into an important actor . '' His most famous role was in the 1987 movie `` The Lost Boys , '' in which Haim played a fresh-faced teenager whose brother becomes a vampire . In recent years , the actor was reunited with longtime friend and frequent co-star Corey Feldman in a reality show . `` The Two Coreys '' ran for two seasons on the A & E Network before it was canceled .
