Smoking tobacco News ABC Science

Smoking and psychiatric risk news "Although it is always difficult to determine the direction of causation, our findings suggest that smoking is a possible risk factor for developing psychosis, and our findings suggest that smoking should be considered as a possible risk factor for developing psychosis," said James maccabe, CO leader of the Institute of psychiatry at King's College London. However, he added that tobacco is just one of many factors, including certain genes, diet, lifestyle and other influences, that increase a person's risk of schizophrenia. Schizophrenia is a serious mental illness that affects about one in 100 people, usually in early adulthood. But there's a lot of debate about whether it's causal, or whether there's a common gene that makes people more likely to use marijuana and schizophrenia.

McCabe said the latest results on smoking suggest that "perhaps even the real culprit is tobacco, not marijuana," because marijuana users often combine drugs with tobacco. Other experts say the gene for mental illness may overlap that for smoking, but more research is needed to tease out any possible links.

Professor Michael Owen, director of the Institute of psychological medicine and clinical neuroscience at Cardiff University, said: "the combination of genetic analysis and longitudinal epidemiological study design is expected to help solve some of these problems.". "It's hard to prove causality without randomized trials, but there are already plenty of good reasons to be very aggressive in public health measures for people with mental illness."
