Nicotine Addiction Linked To Mental Illness
Mental illness is associated with both higher rates of smoking and higher levels of smoking among smokers. Further, a significant proportion of smokers have mental illness. For example, a study by The Journal of the American Medical Association reported that individuals who live with mental illness and/or substance abuse disorders consume 44.3 percent of all cigarettes in America.
Strategies that address smoking in mental illness, and mental illness among smokers would seem to be important directions for tobacco control. As the majority of smokers with mental illness are not in contact with mental health services for their condition, strategies to address mental illness should be included as part of population health-based mental health and tobacco control.
People living with mental illness have a very high rate of smoking. A study by The Journal of the American Medical Association reported that 44.3 percent of all cigarettes in America are consumed by individuals who live with mental illness and/or substance abuse disorders. This means that people living with mental illness are about twice as likely to smoke as other persons.
A positive note is that people who live with mental illness had substantial quit-rates, which were almost as high as the group without mental illness. NAMI has led many changes in our mental health system─getting access to the tools to quit smoking is a way to improve the quality and quantity of life. Improving lives is a new advocacy pursuit.
There is no one single, certain reason why so many people who live with mental illness smoke. It may be a combination of brain effects, psychological effects and the social world in which we live.
From a brain-based perspective, research is being done to determine if and how nicotine is involved in some of the brain’s memory functions. If nicotine is a factor, then this could explain why so many people living with an illness like schizophrenia or other illness involving cognitive deficits may smoke. Even though smoking is thought to enhance concentration and cognition, the effects are short in duration.
Researchers and the medical community have a great deal to learn about how smoking impacts the brains of those living with mental illness. It is known that people diagnosed with schizophrenia often smoke before the onset of symptoms and that they smoke more often and inhale more deeply than smokers without schizophrenia.
