It has been seen that in various developed countries, there is rise in the rates of cannabis use among young people. Many debates have taken place that with respect to cannabis use which has proved that it is a highly contributory cause of psychosis that may precipitate schizophrenia in vulnerable individuals. However, it is assumed that that cannabis use is not the only factor behind causing same as along with many others including genetic predisposition and other unknown causes, the main disease take place, that is, schizophrenia (Jonsson, Birgisdottir &Sigurdsson, 2014).

Literature Review

According to Jonsson, Birgisdottir &Sigurdsson, (2014) cannabis can be termed as the preparation of Cannabis plan that is majorly used for making the use of psychoactive drug or medicine. The worm cannabis is derived from the cannabis plant cannabis sativa. It is mainly found in tropical and temperate areas of the world. The main aspect regarding same is that the main active ingredient in cannabis is called delta-9 tetrahydro-cannabinol which is in common termed as THC. It is mainly helpful in relieving severe pain, nausea, and other chronic conditions however, its regular use may lead to issues related to mental disorders. In the words of Yücel (2012) schizophrenia is a chronic brain disorder with which about one percent of the total population is suffering. At the time when schizophrenia is active, person generally feels symptoms like delusions, lack of motivation, hallucinations as well as trouble with thinking and concentration. It has been seen that use of cannabis put a high risk of development of schizophrenia in individuals consuming the same on regular basis.

As per the views of Large & (2011) over the past 30 years, the evidence has been gained by the medical professionals that use of cannabis lead to the risk for psychosis which ultimately results in schizophrenia in most of the cases. It has been clear by many tests conducted by doctors that there is a strong link in between cannabis use and psychosis. In accordance with the systematic search where there have been yielded 14 cohort studies carried out in 9 cohorts and 9 case-control studies. While accumulating the results of these studies, the major outcome gained is that they unambiguously support the fact that cannabis use is an independent risk factor behind occurrence of psychosis that may ultimately lead to chronic psychotic disorders like schizophrenia. However, Casadio & (2011) says that with increase in the use of cannabis, there is high risk of development of schizophrenia. In addition to this, in adolescence, risk of developing psychosis is high in comparison to the use of cannabis in adulthood. It can be said that psychotic disorders take years to evolve as well as they remain for a long period of time. Therefore, it is necessary to enhance public knowledge regarding the possible consequences of using cannabis on regular basis as nobody knows that the use of same will affect the individuals in which way, that is, whether in the form of transient psychosis or in chronic psychotic disorder. However, they both are dangerous for a person to lead a normal life.
