    Schizophr Bull 38:873-80. 2012
    ..We aimed to clarify the role of age at onset and cognition on outcomes in cannabis users with first-episode schizophrenia as well as the effect of cannabis dose and cessation of use...

    Biol Psychiatry 66:586-93. 2009
    ..Limited evidence suggests that attentional set-shifting deteriorates over time in schizophrenia. We tested this hypothesis and examined the specificity of learning impairments identified by this task...
