Smoking and Schizophrenia or Other Mental Illness

Understanding how and why patients with schizophrenia use nicotine is likely to help to develop better treatments for both schizophrenia and nicotine dependence.It has been seen patients with schizophrenia have higher chances of smoking/tobacco, alcohol  and other drug abuse than the general population. According to one of such study shows that about 40 percent of respondents with past-month mental illnesses are current smokers, which is about double the rate of those with no mental illness.

In clinical samples, the rate of smoking in patients with schizophrenia has ranged as high as 90 percent. Many theories have been proposed to explain the strong association between schizophrenia and smoking.  Most of these relate to the nicotine contained in tobacco products. Nicotine may help compensate for some of the cognitive impairments produced by the mental disorder and may counteract psychotic symptoms or at least upto certain limit subside unpleasant side effects of many antipsychotic medicines. Nicotine or smoking behavior may also help people with schizophrenia deal with the anxiety and social stigma of their disease.

One more study that explain relation between chain smoking and schizophrenia is that the presence of abnormalities in particular circuits of the brain that may predispose individuals to schizophrenia, increase the rewarding effects of drugs like nicotine, or reduce an individual’s ability to quit smoking.

It has been observed that both nicotine and an antipsychotic  like clozapine ( also acts at nicotine receptors) can improve attention and working memory . Clozapine is effective in treating individuals with schizophrenia. It also reduces their smoking levels.
