Adolescent brains exposed to THC are at higher risk of psychiatric disorders

THC exposure during adolescence may cause microglial cell death and brain changes, increasing schizophrenia risks in genetically susceptible individuals.
 
Earlier, a 2023 study found heavy marijuana use may trigger schizophrenia, particularly in young men. This study examined the health records of nearly 7 million Danish citizens and determined that up to 30% of schizophrenia diagnoses — around 3,000 in total — could have been prevented if young men hadn’t abused marijuana.
