Researchers at the University of Queensland’s Queensland Brain Institute and School of Population Health “have found young adults who use cannabis from an early age are three times more likely to suffer from psychotic symptoms.” The study, which followed 3800 people born in the early 1980s until now has revealed that “those who use cannabis for six or more years have a greater risk of developing psychotic disorders or the isolated symptoms of psychosis, such as hallucinations and delusions.”
