Malicious smokers have a higher risk of subsequently becoming ill schizophrenia compared to those who do not have this addiction. This was recently announced by scientists from the UK, publishing the results of a new study.
Experts analyzed data from 60 different studies on the effect of nicotine on the structure of the human brain. In total, data on more than 14,000 smokers and 27,300 non-smokers were carefully studied.
As a result, scientists concluded that smoking directly affects the development of mental disorders. This effect is especially pronounced on young and young people. 57% of patients who suffer psychosis, at the time when they had the first attack of a mental illness, they were smokers. Researchers calculated that nicotine-dependent people are twice as likely to develop schizophrenia as those who do not smoke. This pattern, of course, does not mean that every cigarette lover will necessarily get schizophrenia. But the likelihood of developing this mental illness in smokers is significantly increased. Experts say that under the influence of nicotine there is a change in the level of the substance dopaminein the brain, which leads to the manifestation of psychosis and schizophrenia. Currently, scientists plan to carry out new long-term studies that will allow us to study in more detail the relationship between smoking and the development of mental illness.
Meanwhile, Japanese scientists recently reported the discovery of a connection between smoking and manifestations. breast cancerin young women. The long-term study involved 848 women, whose condition was monitored by specialists for 23 years. They managed to find out that in women who smoked for more than 20 years, the likelihood of premature death increased three times. Moreover, women were 3-4 times more likely to die precisely because of the development of their breast cancer. Therefore, throwing this addiction to both men and women should be done as early as possible.
