The objective of my thesis is to explore schizophrenia and the addictions of nicotine and caffeine with the help of library research. My hypothesis is that people with schizophrenia who do not have access to the delusional metaphor of psychoanalysis exhibit more frequent addictions to nicotine and caffeine. My thesis begins by exploring schizophrenia from a psychoanalytic perspective. My thesis continues by exploring the addictions of nicotine and caffeine in the lives of people with schizophrenia by referring to psychiatric and biologically based studies. While my thesis helps with a semi-structured interview which I had with psychoanalysts who work at 'Shine : Supporting People With Mental Ill Health', it is worth it to write that this organisation used to be named 'Schizophrenia Ireland' until February 2009. My thesis continues by exploring how an individual with schizophrenia and addiction can recover with a delusional metaphor from psychoanalysis. My thesis draws to a close by concluding that: (1) there is a need of further empirical studies, especially in our country, which can help to clarify the consequences of nicotine and caffeine addictions of people with schizophrenia and (2) my thesis supports my hypothesis that people with schizophrenia who do not have access to the delusional metaphor exhibit more frequent addictions to nicotine and caffeine.
