as far as I remember he had a reaction to Aspirin or something...
Death by "misadventure"
A foreshadowing of events to come occurred on May 10th, 1973 when Bruce Lee collapsed in Golden Harvest studios while doing dubbing work for Enter the Dragon. Suffering from full-body seizures and cerebral edema, he was immediately rushed to the hospital where doctors were able to reduce the swelling through the administration of Mannitol and revive him. These same symptoms that occurred in his first collapse were later recapitulated on the day of his death.[67]
On July 20, 1973, Lee was in Hong Kong, due to have dinner with former James Bond star George Lazenby, with whom he intended to make a film. According to Lee's wife Linda, Lee met producer Raymond Chow at 2 p.m. at home to discuss the making of the movie Game of Death. They worked until 4 p.m. and then drove together to the home of Lee's colleague Betty Ting Pei, a Taiwanese actress. The three went over the script at Pei's home, and then Chow left to attend a dinner meeting.
A short time later, Lee complained of a headache, and Ting Pei gave him a now-banned powerful analgesic (painkiller), Equagesic, which contained both aspirian and a muscle relaxant. At around 7:30 p.m., he went to lie down for a nap. After Lee did not turn up for dinner, Chow came to the apartment but could not wake Lee up. A doctor was summoned, who spent ten minutes attempting to revive him before sending him by ambulance to Queen Elizabeth Hospital. However, Lee was dead by the time he reached the hospital. There was no visible external injury; however, his brain had swollen considerably, from 1,400 to 1,575 grams (a 13% increase). Lee was 32 years old. The only two substances found during the autopsy were Equagesic and cannabis. On October 15, 2005, Chow stated in an interview that Lee died from a hypersensitivity to the muscle relaxant in Equagesic, which he described as a common ingredient in painkillers. When the doctors announced Bruce Lee's death officially, it was ruled as "Death by Misadventure."
Another theory is that he died from an allergic reaction to Cannabis which he was consuming at the time in hashish form.[68] While the theory is controversial, it is supported by both Don Langford (Lee's personal physician in Hong Kong) and Peter Wu (the head neurosurgeon who saved Lee's life after his first collapse).[69] At the very least, Wu suggests that the official Inquest on his death should have concluded that his death was due to a hypersensitivity to Equagesic OR cannabis, as the role of cannabis could not be entirely ruled out. He also points to the fact that Equagesic was not present in Lee's body during his first collapse. [67] It should be noted that a accepted use of Cannabis in medicine is as a anti-inflammatory agent, which is in opposition of Bruce's official cause of death, swelling of the brain.
However, the exact details of Lee's death are controversial. Bruce Lee's iconic status and unusual death at a young age led many people to develop many theories about his death. Such theories about his death included murder involving the Triad society and a supposed a curse on Lee and his family. The theory of the curse carried over to Lee's son Brandon Lee, also an actor, who died 20 years after his father in a bizarre accident while filming The Crow at the young age of 28. Like his father's last film, released after his death to gain cult status, Brandon's last film The Crow was also released after his death, completed with the use of computer-generated imagery and a stunt double in the few remaining but critical scenes that Brandon had left unfilmed at his death.
The grave site of Bruce Lee and his son, BrandonUpon the death of her husband, Linda returned to her home town of Seattle and had Bruce buried at lot 276 of Lakeview Cemetery. His son Brandon was buried beside him. Pallbearers at his funeral on July 31, 1973 included Steve McQueen, James Coburn, Chuck Norris, Dan Inosanto, Taky Kimura, Peter Chin, and his brother, Robert Lee.
