List someone famous that has taken LSD. No obvious ones like Timothy Leary or Hendrix. I'll start it with... Groucho Marx
Groucho Marx, very interesting... I don't know how much merit this holds because there's no link for proof but Erowid's Character Vaults list Bill Gates, Cary Grant, and Jack Nicholson (not too surprised) as having used LSD.
come on, no guessing janis is obvious, henry ford I doubt it, but possibly Michael jackson, agian I doubt it. and they should be people that can be verified they took it.
Pretty sure Carl Sagan. Dunno if it can be 100% verified, but I've heard him make refrences that very strongly suggest he did, and come on...it's Carl Sagan.
he was a daily pot smoker, he and his wife, ever since his early twenties, so I am willing to bet he experimented with other things as well
Steve jobs from apple did Albert even wrote to him http://m.gizmodo.com/5310549/lsd-creator-albert-hofmann-to-steve-jobs-how-was-lsd-useful-to-you
