I don't disagree that these substances are known triggers for those with predispositions, but be careful with your logic - that's exactly the same format as autism/vax conspiracy folks use, when in reality the common cause is age. Symptoms of autism can start to manifest around the time childhood vaccines are being given, just like schizophrenia and related conditions manifest in teenagers and young adults (also groups known to try drugs). In the latter case we do also have evidence that psychedelics are associated with increased risk/earlier onset, but you wouldn't be able to tell from the timing anecdote.
