> Are you telling me you've never met an old LSD abuser whose brain was fried like an egg?

I’ve known old LSD abusers with fried brains but never seen a LSD abuser go from non-fried to fried brains. Correlation is not causation, but it could be.

> LSD can also trigger legitimate lifelong psychotic states in some people.

These statements should be accompanied by the necessary caveat that just about anything can trigger psychotic states in people prone to psychosis.
