Dr. Conrad Murray's lawyers just filed blistering legal docs, claiming Dr. Arnold Klein -- Michael Jackson's longtime doctor and friend -- addicted him to Demerol and another powerful narcotic.
In legal papers obtained by TMZ, Murray's legal team claims Klein fueled MJ's drug dependency by giving him scores of Demerol injections in the months prior to his death. TMZ broke the story ... in the 3 months before Jackson died, Dr. Klein gave MJ 51 Demerol injections.
The docs claim, "Due to Mr. Klein's actions, Mr. Jackson became physiologically and psychologically dependent on Demerol."
Murray's team wants Klein to produce all his medical records, claiming "Dr. Klein is a relevant and highly material witness to the defense."
