I think it does, I've seen it happen to a friend who had a tab then had a psychotic break, he still has to take anti-psychotics and its been like 4 months.
He's 17 too...
He's 17 too...

i have personally watched a very close friend have a psychotic break after ingesting 44mg of 4-AcO-DMT, he was a high functioning student at a top 10 university and had to be institutionalized shortly afterwards, more than two years have passed and he has not recovered. so short answer - yes they can.
You'd think if LSD caused schizophrenia there would be a corresponding increase in schizophrenia rates tho.
Here's the same argument for the "cannabis causes schizophrenia" claim:
Countries which had extremely high cannabis use (Jamaica in 1995] had the same schizophrenia rates per 1000 as countries with zero cannabis use (Norway in 1926-1935).
Q: Does cannabis use cause schizophrenia?
A: No. Over the past four decades most countries in the Western world have experienced rapidly increasing cannabis use. None of these countries has experienced any accompanying “Madness” plague. Countries like Australia and Jamaica which have the highest levels of cannabis use have levels of schizophrenia similar to the rest of the world.
We’ve smoked the “Reefer” for four decades, and “Madness” levels have remained steady, not just in Australia, but all over the world.
Where does that leave the “Reefer Madness” theory??

Perhaps trigger, but not cause.
