Secondhand smoke may cause mental problems: Published: 2010-06-09 Views:114 reads; BEIJING, June 9 (Xinhuanet) -- A new research showed that non-smokers who have passive smoking were 50 percent more likely to get mental problems than those absolute non-smokers, according to news reports on Wednesday.

The research led by Dr Mark Hamer of University College London pointed out that non-smokers being exposed to smoking are seen everywhere.

Dr Hamer and his colleagues studied more than 5,000 non-smokers and more than 2,500 smokers with none of them having mental illness prior to the study. But by the end of the study, an amount of 14.5 percent of them showed evidence of psychological distress.

The results indicated non-smokers were 62 percent more likely to report mental problems than those unexposed to secondhand smoke, and the risk for smokers was more than two times higher than non-smokers.

"Taken together, therefore, our data are consistent with other emerging evidence to suggest a causal role of nicotine exposure in mental health," the research concludes.
