There is zero proof he loved drugs. The only thing I've ever heard (and I'm an enormous Bruce fanatic) is that he ingested hashish and took a prescription pain killer for a headache from some actress and that led to his cerebral edema/death. But yeah, pretty sure he cheated on his wife a good bit. Still, what the man accomplished in his life (he died younger than I am right now) is insane. Saying he was prolific and decades ahead of his time doesn't even due him justice.
