Link Between Second-Hand Smoke and Mental Health Noted


Constant exposure to environmental tobacco smoke can cause mental health disorders, a recent study from the University College London published in the Archive of Pediatrics and Adolescent Medicine reveals.

Culling data from the Scottish Health Surveys conducted in 1998 and 2003, the researchers analyzed the mental health of 5,560 non-smoking adults and 2,595 smokers, all of whom have no prior history of mental sickness. Questionnaires were designed to show the psychological distress level of the participants, while the non-smokers were tested for the nicotine metabolite cotinine in their blood.

After 6 years of monitoring, the results show that 14.5% of all the participants have psychological distress and 41 participants were admitted to psychiatric institutions. Non-smokers who were found to have 0.70-15 micrograms of cotinine reported higher level of mental stress compared to those with negligible levels of the nicotine metabolite.
