It is based on the fact that serotonin (5-hydroxy-tryptamine) gets converted into bufotenin, a psychedelic drug which is called bufotenin or 5-hydroxy-dimethyltryptamine. Psychedelics have been known to bring great things to an individual. The same applies for autism.

No, most toads are not psychedelic. The one toad that is commonly used for recreational purposes is Bufo alvarius, which secretes bufotenin and 5-methoxy-dimethyltryptamine. The related species Bufo marinus also secretes bufotenin, but in addition it secretes large amounts of other toxins which makes it dangerous to ingest its secretions. The exact effects of bufotenin are somewhat disputed, but it appears to cause more unpleasant physical effects and less psychedelic effects than compounds such as psilocybin.

No. The real drug responsible for Autism is a psychedelic called bufotenin, or 5-HO-DMT. It is naturally produced by their brains, eliminating serotonin in the process.

I have HPPD as a result of Autism, due to natural production of a psychedelic called bufotenin. About 1 in 100 people are autistic. There is a chance that these two disorders are linked together.

Autism primarily affects the functionality of the brain. Serotonin gets converted into a hallucinogen called bufotenin, indicating a completely different way of thinking and perception through senses.
