YEREVAN, JULY 10, ARMENPRESS. Smoking cigarettes might increase people’s risk of psychosis, say researchers who believe tobacco as well as cannabis could play a part in causing schizophrenia. As Armenpress reports citing “Guardian”, the aforementioned was informed by the scientists from King’s Institute of Psychiatry. It has long been recognised that people suffering from psychosis tend to smoke more than most of the population, but it has generally been assumed they are self-medicating. “Having psychosis is a very distressing thing – hearing voices, having delusions,” said Dr James MacCabe from King’s Institute of Psychiatry, Psychology and Neuroscience, one of the authors of a new study.
