Everybody is different, but the combination of those 4 particular drugs killing someone seems unlikely to me. Coke maybe, but the other three? Plenty of people do those substances without getting fucked in the head, in a lot of cases they (except coke) help them mellow out. Saying weed killed Bruce Lee is something out of the anti drug PSAs from the 90s lol
It did to me too, but with all else about his strange death, that is the best option, Len Bias died after trying coke just one time. there was a lady who died similarly to Bruce, a singer, Nicolette Larson, who died of cerebral edema, same thing as Bruce "officially" and it sounded like she had liver problems. That lady runner, gorgeous woman, .......,,,,,,Flo Jo, died of an epileptic fit (bruce had seizure's during his last days, including his final one) and people wondered if Florence's PED use may have had something to do with it.
It's still a mystery though, I just say the drugs make things perhaps slightly clearer and give us the best reason we have that he died. Street drugs have taken out a lot of our icons and prescription pills have too.
You have to look at the other reasons though to see just how ridiculous some of them are and see my logic, triads, murder, poisoning, a family curse. I do believe a curse is possible, as an Indian who's had relatives who've seen such things, and I do believe in the unseen but I'd believe on what we do know before any of that.
The authorities knew about the some of the drug use at least, initially, they knew about the marijuana, it sounds like they didn't look for anything else and Hong Kong really didn't have a huge drug trade in those days from what I know. Had Bruce been caught getting that stuff in the mail, he would have been in legit hot water. Speculation over on the Bruce Lee site is that Bruce may have been a dealer, he was a star in his last days but he wasn't yet rich. It looks like Linda went along with all of it according to her letters and also her appearance, they both were emaciated around the time Bruce died. She later try to say he was on some ridiculous diet of an apple or carrot juice to cover up how bad bruce looked and he looked bad in the face in his last days, go look at pics from enter the dragon and look at pics from his first hong kong film in the 70's, he looks so much healthier and vibrant.
I used to think all the work had something to do with it but one thing the guys on the other site have pointed out was that Bruce really wasnt that busy making films, four films in 2-3 years isn't that insane, especially for low budget stuff like that. He had down time between shooting and also interestingly held up shooting on ETD for a week, everyone thought it was nerves, but, maybe he was trying to clean up a bit and get his head on straight.
As I've said, the drug letters just give us a little bit more than we had before but it's still mysterious and still a rabbit hole.
