Apparently, according to a new research, people smoking tobacco might possess a greater risk of developing schizophrenia and depression. Researchers from the United Kingdom has added weight to increasing evidence that people who smoke can have a negative effect on their mental health. Genetic data has been used by the researchers to analyze cause and effect connections with smoking, rather than just looking at whether the smokers has a genetic predisposition to schizophrenia or depression. Robyn Wootton, the lead author of the study said that, individuals having mental illness are overlooked often in their efforts to lessen smoking prevalence.
He added by saying that, we must be taking every single effort to prevent initiation of smoking and encourage smoking cessation as the consequences to mental illness along with physical health. Data from nearly 462,690 individuals was studied by scientists belonging to European ancestry using an approach known as Mendelian randomization. It had been concluded by the researchers that while smoking augmented the danger of schizophrenia and depression, people having schizophrenia and depression are more probable to smoke. However, it was noted by the authors that, the bond was weaker in those having schizophrenia.
It was found by the same team that, the danger of bipolar disorder is also increased by smoking, according to additional study of Mendelian randomization printed in the month of September. It has been recommended by the researchers that the psychiatric hospitals should be made free from smoke in order to prevent detrimental effects on mental health. The whole study was printed recently in the journal Psychological Medicine. As per David Curtis an honorary professor and a retired consultant, it is plausible that the brain gets directly played by smoking to increase the risk of schizophrenia, and results possible demonstrate the effect of mothers smoking while being pregnant.
