Did Einstein ever use drugs

Answer 1

No, there is no credible evidence of it. Sad to say, there is a lot of speculation coming from various websites, but nothing close to actual proof. What we do know is that Einstein was a heavy smoker, and frequently was seen with his favorite tobacco and his pipe. He did not drink much, and claims that he used cocaine or LSD are doubtful-- even Timothy Leary, the biggest proponent of using LSD, stated that to his knowledge, Einstein did not use it. Einstein died in 1955, from internal bleeding caused by a burst blood vessel, or a ruptured abdominal aortic aneurysm-- he had previously had surgery in that same region of his body in 1948; and although some websites have claimed it "could be" caused by cocaine use, that too is difficult to accept, since there are many possible causes of aneurysms. That said, he certainly might have tried a drug at some point in his life, but those who knew him, including biographers, have never reported any ongoing use of drugs.
