Also, the article clearly states "Cannabis / Marijuana (and other street drugs) Significantly Increases a Person's Risk for Schizophrenia ", key word that this research group clumps cannabis with "other street drugs". Also, just because the samples had never been TREATED for psychosis or schizophrenia does not mean that they had no pre-existing medical conditions of that nature. In addition, what is the integrity of the study which guarantees that none of the samples were using any other street drugs or taking any other medication, as well as any other genetic or social variables which would contribute to such a diagnosis? Furthermore, what exactly does "schizophrenia-spectrum disorders" mean? What is the margin of human error and mis-diagnosis? Even furthermore, the aticle is quoted with stating: "Cannabis use is associated with poor outcome in existing schizophrenia and may precipitate psychosis in individuals with preexisting liability." Yes, PRE-EXISTING LIABILITY. Which means any number of x-factors may have set off "schizophrenia-spectrum disorders". I have just taken the PRIME Early Screening Test for Schizophrenia and Psychosis and was informed that "Your answers to the schizophrenia screening test DO NOT suggest that you have the early signs of psychosis or schizophrenia" i mean if i would have been able to answer those questions in a manner indicating that i agree, i know i would be fuckin crazy, and up until four weeks ago, i have been a HEAVY cannabis smoker for the past 5 years since age 17. But i guess you can say i have been one of the lucky ones, whatever that means. Also, i cant quite make sense of the x-axis in relation to the y-axis of the risk graph displayed at page:
