I don't think he was looking for "help" any more than when he was abusing medical grade LSD.
He was looking for a new kind of kick. So was Timothy Leary but he didn't make the same mistake as Leary in thinking that this was the "answer" to life.
I wasn't aware Cruize had a history with LSD. Scientology used to have some severe restrictions on anyone that used LSD anytime in the past. I believe it was because they didn't understand it. LOL like anyone did...
