Which environmental trigger is linked to the risk of developing schizophrenia?

Regular cannabis use has been identified in research as an environmental trigger that can increase the risk of developing schizophrenia, particularly in individuals who may be genetically predisposed to the disorder. Studies indicate that the psychoactive components of cannabis, especially THC (tetrahydrocannabinol), can induce psychotic symptoms and may accelerate the onset of schizophrenia in vulnerable populations. This connection is particularly strong among adolescents, who are at a critical developmental stage regarding mental health. The risk associated with cannabis is amplified when use begins at a younger age and when heavy use occurs frequently.

In contrast, high levels of education, stable family relationships, and adequate nutrition tend to be protective factors that can contribute to better mental health outcomes. Education may provide individuals with skills and resources to cope with stressors, stable relationships can offer emotional support, and adequate nutrition is essential for overall mental and physical health. These factors are generally associated with a lower risk of developing psychiatric disorders, contrasting with the adverse effects linked to cannabis use.
