Sorry, but I'm just going to trust my own observations of reality over some random paper. It's plainly obvious that these drugs trigger schizophrenia and other mental illnesses in a percentage of people who use them. Sometimes all it takes is a single use even. If you haven't met people who have had this happen to them then I advise you to search online for people's stories since it's not that hard to find them.
