I suspect there's some vague "psychosis level" that spikes and decays exponentially when you use weed, lsd, etc. And then people with schizophrenia find these drugs near age 20 just as the level is rising naturally. So it looks like LSD triggered it but there's no real interaction besides adding the two curves.
