Harvard Study: Smokers 'More Likely To Be Depressed'

Researchers from the University of Navarra and the University of Las Palmas De Gran Canaria in Spain, along with experts from Harvard University, have linked depression to tobacco use after completing a six-year study.

The results of the study, published in Spanish health journal Medicina Clinica, suggested that former smokers who had not had any tobacco in the last decade were the least likely to develop depression.

“A significantly higher risk was found for smokers when they were compared to non smokers, whereas an inverse association was found for ex-smokers who had quit smoking more than 10 years ago,” the researchers said.

“This study supports an increased risk of depression associated to smoking.”
