An earlier age of onset of#schizophrenia#has been identified as a poor prognostic indicator. The current study examines the interaction effect of gender and#cannabis#use on age of onset of#schizophrenia#and schizoaffective disorder. This research forms part of a two-centre epidemiological study of first-episode psychosis and included individuals with a diagnosis of#schizophrenia#or schizoaffective disorder and an age of onset between age 16 and 45. Kaplan-Meier curves and Cox proportional hazards regression were used to compare the effects of#cannabis#use and gender on age of first symptom of#schizophrenia. Akaike's information criteria were used to find the model with the best fit to the data.#Cannabisusers had an earlier age of first symptom than non-users. There was an interaction with gender; the gender difference in age of onset was diminished in#cannabis#smokers compared with non-cannabis#smokers. The model including#cannabisuse interacting with gender was the most parsimonious model, followed by#cannabis#use alone. The addition of other illegal drug use did not improve the model.#Cannabis#use is associated with an earlier age of onset of#schizophrenia, and the gender difference in age of onset is reduced among#cannabis#smokers.Copyright © 2014 Elsevier Ireland Ltd.

I generally find people who attemp to disagree with this or form opinions on the subject are for the legalization or simply smoked pot when they were young and with bias assume it therefore must be a non-issue. Why do you disagree, what research have you read or participated in that shows otherwise?
Who do you know that has done research suggesting that there is zero link between the use of cannibin and onset of mental illness?
And if your for the legalization of marajuana try not to let your bias cloud your judgement because i'm actually completely indifferent to it and without bias. I just waded into the thread to see if there was anything interesting and came across a few ignorant statements.
