A new study projects what might happen to the incidence of schizophrenia whether there is a relationship within marijuana use and schizophrenia. whether cannabis use causes schizophrenia, these increases in its use would lead to increases in overall schizophrenia incidence and prevalence of 29 per cent and 12 per cent respectively, amidst 1990 and 2010. It’s worth noting that even public who believe that there is a relationship, believe that the risk is low. (Incidence is defined as the frequency of new occurrences; and prevalence is the percentage of the population affected by the disease.)

If cannabis causes schizophrenia - and that remains in question - next by 2010 up to 25 per cent of new cases of schizophrenia in the UK may be due to cannabis, according to a new study by Dr Matthew Hickman of the University of Bristol

and colleagues, published in Addiction journal.

Substantial increases in both prevalence and incidence of the disease are forecast by the end of the decade, with increases in schizophrenia starting earlier among young men in specific.

The research study matches historic trends in cannabis use and exposure from a national population survey against estimates of new occurrences of schizophrenia in three English cities (Nottingham, Bristol and the London Borough of Southwark).

The researchers assess what might happen to schizophrenia cases whether we assume a causal link within cannabis use and onset of psychotic symptoms, an organization widely recognised by some psychiatrists and researchers and considered recently by the Advisory Council on the Misuse of Drugs.

Exposure to cannabis grew fourfold by the thirty years to 2002, and its use among under-18s by 18-fold, say the researchers.
