ISLAMABAD: Smoking tobacco is associated with an increased risk of developing psychosis, such as schizophrenia, according to a new study.
Researchers from King’s College London conducted a meta-analysis of 61
observational studies comprising almost 15,000 tobacco users and 273,000 non users.
They analyzed rates of smoking in people presenting with their first episode of psychosis and found that 57 percent of these individuals were smokers,Xinhua reported.
The results also showed that daily smokers developed psychotic illness
around a year earlier than non-smokers.
It is thought that activity within the brain’s dopamine system might be one explanation of a possible causal link between smoking and psychosis, according to the study.
