A well researched individual who is curious about LSD will know that LSD can trigger schizophrenia in people who are genetically predisposed for schizophrenia. If you aren't genetically disposed to schizophrenia, LSD is not going to cause schizophrenia. Greater amounts of studies and scientific research into drugs like this increase our knowledge and make their informed usage much less risky.
