Schizotypy and substance use

Chapter


Abstract


  • The relationship between substance use and psychotic disorders has pro

    -

    duced much controversy in clinical, public policy and research domains.

    Given the role of regulators in determining the legality of substances of

    abuse, the relationship between substance use and psychosis has been a

    matter for contentious debate. Counter to these discussions, however, is the

    indication that the most commonly used substances in patients with schizo

    -

    phrenia, and those who express schizotypal traits, are alcohol and nicotine.

    There is evidence that substance use patterns are established before the

    onset of illness. Therefore, consideration of substance use in relation to

    schizotypy may help to elucidate the nature of the relationship between risk

    and substance use. Ross and Peselow (2012) provide a classification system

    for the potential relationships between psychotic and addictive disorders,

    which is equally relevant to schizotypy. The diagnostic formulation has been

    adapted to reflect schizotypy here.
