Dopamine release in the nucleus accumbens and the prefrontal areas is associated with several pleasurable and reinforcing activities, such as eating and sex, as well as the use of drugs such as cocaine and amphetamines (22). Nicotine has been shown to improve cognitive deficits in individuals with psychosis, including working memory and attention, 42 –45 and in this context nAChRs have emerged as targets for the treatment of cognitive and negative symptoms.

By increasing the release of dopamine, nicotine is believed to produce similar results for patients with schizophrenia. Ziedonis and George (33) conducted a ten-week smoking cessation program for 24 volunteer outpatients with schizophrenia. This stimulation of dopamine could help explain the high use of nicotine as a form of self-medication to reduce negative symptoms (18). Nicotine and antipsychotics.
