Secondhand Smoke Harms Mental Health?


Exposure to secondhand smoke has previously been associated with negative physical health outcomes, but a recent study has linked it to worse mental health outcomes as well. During a six year study, researchers found that non-smokers with the highest exposure to secondhand smoke had greater psychological distress and greater likelihood of being hospitalized than those unexposed to secondhand smoke. Secondhand smoke exposure was measured through the levels of cotinine in their saliva, and mental health was measured using questions about psychological distress and admission to a psychiatric hospital.
