Testing the biosocial cognitive model of substance use in cannabis users referred to treatment

Cannabis is the most commonly used illicit drug worldwide (Hall, 2015). The global number of cannabis users is estimated at approximately 125 – 203 million people, or 2.8% - 4.5% of the global population (Degenhardt and Hall, 2012). Of those who ever try cannabis, it is estimated that 10% will become daily users and 20 – 30% will become weekly users (Hall and Pacula, 2003). Engaging in frequent and persistent cannabis use is associate d with increased risk for adverse outcomes including cannabis dependence (Hall and Degenhardt, 2009), long-term cognitive impairments (Solowij et al., 2002) and psychosis (van Os et al., 2002).
