Young people who use marijuana for a long time tend to be more frequent hallucinations, imagined or show symptoms of psychosis (mental illness) than those who occasionally or never even smoked marijuana.
The researchers evaluated 3801 young adults and determine whether they are experiencing psychosis symptoms. The study published in Archives of General Psychiatry found that the young longer and more frequent use of cannabis tend to hallucinate.
Overall, 233 participants have at least one positive report hallucinating and 65 participants were diagnosed with non-affective psychosis, like schizophrenia.
“Compared to those who have never smoked marijuana, young adults who had used cannabis during the six years or more risky two-fold greater occurrence of non-affective psychosis,” said the researcher, as quoted webmd.com site.
Non-affective psychosis, explained researcher John McGrath, MD, of the University of Queensland in Brisbane, Australia, is a broad category that includes schizophrenia and other disorders such as delusional disorder. Patients with this disorder, further MsGrath, do not have a prominent element of mood.
Depression
“Just like depression. Many of us are experiencing symptoms of mild to moderate depression, but does not meet the criteria for clinical depression. So also with psychosis, they have their own symptoms, but does not cause obvious problems.”
In addition, the study also showed that those who had used cannabis for at least six years had a score of delusional experiences (imagining) four times greater.
The longer the duration time is calculated from the first time use of marijuana, bright researchers, the higher the risk of psychosis.
