The THC in cannabis can destroy critical neuronal pathways in the developing brain, which can result in permanent brain changes. The worst case scenario is psychosis that becomes permanent and is then considered schizophrenia, a life-long, debilitating disease. No one can predict in advance who will be susceptible, as some can experience symptoms after a few times of use. The mental health harms of cannabis are well known to scientific researchers. Professionals say the evidence found in peer-reviewed studies is undeniable: THC in cannabis, even in low concentrations, can cause psychosis. And out of the drugs that can cause a temporary episode of psychosis, marijuana/cannabis has the highest conversion rate to chronic psychotic disorders like bipolar and schizophrenia. |
Symptoms of psychosis are: paranoia, feelings of doom, irrational thoughts or behaviors, delusions, confusion, hearing voices or seeing people who are not there, and inability to communicate coherently.
Cannabis Induced Psychosis (CIP) is listed in the DSM-5, Diagnostic and Statistical Manual of Mental Disorders, a manual used by medical professionals for assessment and diagnosis.
