Benjamin Le Cook, Ph.D, M.P.H., and colleagues at Harvard Medical School/Cambridge Health Alliance and other institutions used the 2004-2011 Medical Expenditure Panel Survey to compare trends in smoking rates between adults with and without mental illness and across multiple disorders. They also used the 2009-2011 National Drug Use and Health survey to compare rates of smoking cessation among adults who did and did not receive mental health treatment.
The researchers found smoking rates declined significantly among individuals without mental illness (from 19.2% in 2004 to 16.5% in 2011) but only slightly among those with mental illness (from 25.3% to 23.8%). Importantly, however, individuals with mental illness who received mental health treatment in the previous year were more likely to have quit smoking (37.2 percent) than those not receiving treatment (33.1 percent).
In an interview with Psychiatric News, Cook said it is not known when people in treatment had quit, so it cannot be certain that they quit because of treatment. “We can say that people in treatment have quit and have continued to abstain, so there is a positive effect," he said. "The rates are still low, so there is clearly a lot of room for specialty mental health providers to do a better job helping patients quit smoking.”
