The following paper is а critique of “Drugs Induced Schizophrenia”. In order to explain my point I will first explain what schizophrenia is followed by а critique on how drugs can induce schizophrenia, ending with а conclusion.

According to some researchers schizophrenia is an assorted disorder. Schizophrenia is an upsetting disease exclusive of any probable cause. Schizophrenia is approximately universally viewed as the standard paradigm of insanity. Symptoms include delusions, hallucinations, disorganized speech, and lack of emotional response (Hoffer, 1992).

Scientists and doctors have been looking for answers for а long time and they have come up with а few conclusions. Some scientists say that schizophrenia is caused by genetics, while others think it is caused by the brain or drugs. Either which way, there is а cause and scientists and doctors are bound and determined to find it.

The common belief at this point in time is that both biological and environmental factors play а part in determining who becomes schizophrenic.

Schizophrenia tends to be genetic, it run in families. The incidence of schizophrenia is about 12% in the offspring when one parent is schizophrenic, about 50% when both parents are schizophrenic, and about 50% in identical twins of schizophrenics (Young, 1988).

Schizophrenia has been associated with increased levels of the neurotransmitter dopamine, especially in the brain's left hemisphere, and with lowered glucose metabolism in the brain's frontal lobes and basal ganglia. The brain's limbic system has also shown to have а lowered metabolism. Particularly engorged brain ventricles have been instituted in some of the patients suffering by schizophrenia.

After much research is has also been proven that drugs can trigger schizophrenia. Further, drugs which increase dopamine by blocking its reuptake by the DA transporter into nerve terminals such as cocaine and amphetamine cause the positive symptoms of schizophrenia,
