It's good to finally see some common sense on this story. With over 100 million Americans having consumed marijuana (per SAMHSA), we know it is near harmless and famous for causing peaceful, friendly attitudes. The schizophrenia link is bogus, though, as Paul Armentano explains: >>>"The mainstream media loves to spill ink hyping the allegation that marijuana causes mental illness, particularly schizophrenia. In fact, it was in March when international media outlets declared that cannabis use ‘doubled’ one’s risk of developing the disease. Yet when research appears in scientific journals rebuking just this sort of ‘reefer madness,’ it generally goes unreported. Such is the case with a pair of just-published studies slated to appear in the journal Schizophrenia Research. The first study, conducted by a team of researchers at various New York state hospitals, the Yale University School of Medicine, and the National Institutes of Mental Health assessed whether there exists a causal association between cannabis use and the age of onset of psychosis in patients hospitalized for the first time for an episode of schizophrenia. Despite previous media claims to the contrary, researchers concluded: “Although the onset of cannabis use disorder preceded the onset of illness in most patients, our findings suggest that age at onset of psychosis was not associated with cannabis use disorders. Previous studies implicating cannabis use disorders in schizophrenia may need to more comprehensively assess the relationship between cannabis use disorders and schizophrenia, and take into account the additional variables that we found associated with cannabis use disorders.” A separate study slated for publication in the same journal assessed the cognitive skills of schizophrenic patients with a history of cannabis use compared to non-users. Authors reported that patients with a history of marijuana use “demonstrated significantly better performance on measures of processing speed, verbal fluency, and verbal learning and memory” compared to abstainers. Marijuana use was also associated with better overall GAF (Global Assessment of Functioning) scores compared to those of non-users. Authors concluded: “The results of the present analysis suggest that (cannabis use) in patients with SZ (schizophrenia) is associated with better performance on measures of processing speed and verbal skills. These data are consistent with prior reports indicating that SZ patients with a history of CUD (cannabis use disorders) have less severe cognitive deficits than SZ patients without comorbid CUD. … The present findings also suggest that CUD in patients with SZ may not differentially affect the severity of illness as measured by clinical symptomatology.” Both study’s findings are in line with previous (though virtually unreported) research indicating that marijuana is unlikely to instigate incidences of schizophrenia in the general population, that cannabis use among patients with the disease is associated with higher cognitive function, and that at least some schizophrenics find subjective relief from symptoms of the illness by using pot. Nonetheless, odds are the nobody from the mainstream media will be champing at the bit to report on them."
