I know, this isn't scientific, but I met in my life at least 50 people who did all kind of drugs and two of them have problems with schizophrenia and both did smoke much more marijuana, than I could ever do or want. Most of the others stopped at some point to do drugs and are now more or less normal people in their society. I know, this says nothing, but I have become careful with marijuana and don't see it as being completely harmless. This being said, I think that alcohol and tobacco are much more dangerous than marijuana.
