U.S. researchers say they've found a link between quitting smoking and improved mental health.

The results show health professionals should consider the smoking habits of patients with psychiatric problems when treating them, the Washington University researchers said.

They reviewed questionnaires that were part of the National Epidemiologic Study on Alcohol and Related Conditions, which gathered information from just under 35,000 people in the early 2000s.

The data showed quitting smoking, or reducing by half the number of cigarettes smoked daily, was linked to a lower risk of mood disorders like depression, and lowered the likelihood of alcohol and drug problems.

"We don't know if their mental health improves first and then they are more motivated to quit smoking or if quitting smoking leads to an improvement in mental health," lead investigator Patricia Cavazos-Rehg said. "Either way, our findings show a strong link between quitting and a better psychiatric outlook."

The study appears in the journal Psychological Medicine.
