Bruce died from multi-factoral causes. His doctors knew what almost killed him on May 10th, 1973. He even presented it to Dr. Langford, the next day, when Langford came in and interrogated him at the hospital, after saving his life. He wanted to know if Bruce was taking any drugs. There was no other explanation. He pulled out Nepal hashish and Langford told if he started taking this again, it would kill him. He rejected Langford's medical advice and flew to UCLA and was clean. They found nothing wrong with him, because there were no drugs in his system. This gave him a false sense of security and a few weeks before he died, he was ingesting it again. This type of hashish he got from Katmandu, Nepal. It's one of the most near-lethal strains of *unrefined* hashish and is much more rarer than the refined types manufactured in the Middle East.
