Expands on previous analyses of the contribution of illicit drug use to the global burden of disease (GBD). Conducts the first assessment of the global burden of cannabis (e.g. marijuana, hashish and hash oil) dependence. Outlines the methodology used to estimate burden for this disorder specifically. Assembles data on the incidence and prevalence of cannabis use and dependence into a comprehensive disease model which adjusts for known sources of variability between studies. Investigates trends in the burden of cannabis dependence. Investigates the model used in GBD 2010 to estimate the global burden of disease attributable to cannabis dependence as a risk factor for schizophrenia. Looks at the effect on mortality. Includes data from New Zealand.
