Question

Quizplus · Accepted Answer

Drug use, particularly marijuana and other hallucinogens, has been shown to increase the risk of developing schizophrenia or triggering its onset in individuals who are already at higher risk due to genetic or environmental factors. College stress and cigarette smoking in adolescence have not been consistently linked to an increased risk of schizophrenia, while being an only child is not a risk factor at all.
