Schizophrenia is a severe mental illness that affects about 1% of the global population. It is characterized by hallucinations, delusions, and disordered thinking. While the exact cause of schizophrenia is still unknown, research suggests that genetics, brain chemistry, and environmental factors all play a role.
One environmental factor that has been linked to schizophrenia is marijuana use. A new study, which was published on May 4 in the journal Psychological Medicine, found that a shocking 30% of schizophrenia cases among men could be attributed to the use of high-potency marijuana.
The study analyzed data from over 10,000 people who had experienced a first episode of psychosis, which is a common symptom of schizophrenia. The researchers found that young men who used high-potency marijuana frequently were more likely to develop schizophrenia than those who did not use marijuana or used low-potency marijuana.
