Interesting, can you expand on this? First time I hear this. I know someone that told me of a friend of his that hid some LSD at a border crossing close to the body and as a result of the trip, the guy got severe permanent psychatric damage in that he's currently residing in an institution.
I thought he was full of shit, but if what you're saying is true, he might not have been.
Most psychoactive substances may potentiate and escalate some condition, the simplest example would be to get a full cup of strong coffee after a long period of abstinence (if you suffer from anxiety).
In the case of LSD and many other HT2A-receptor agonizing substances I can attest that it has indeed an effect that may result from simple paranoid delusions (I can read what people are thinking of me) to full on panic attacks (They are coming to kill me).
The substance in itself is not what really triggers latent disorders but what stimulates an environment in which a condition may deteriorate very fast, that's not to say that in a controlled, safe environment with the appropriate mindset this may be attenuated or even non existent.
I could digress about anecdotes here, but I don't feel comfortable, so I'll share a link [0] to an irc network where you can probably find someone tripping on LSD right now, just check if the user has |LSD appended to the nickname.
At #drugs people will be glad to talk with you about it, and you may possibly find very helpful information. Just don't do it on #sanctuary or #tripsit as these are there to help people in altered states.
It was incredibly scary that it lasted so long and I was so worried he'd never be the same again.

> Several types of psychoactive drugs have been shown to correlate with psychotic breaks
It is common knowledge amongst psychiatrists and psychologists, and has been for decades. For most people, no problem. For some people, big problem. Most people that have a psychotic break never fully recover from it either.
