Given the widespread use of cannabis, increasing recognition of the potential health effects of this drug and a growing recognition of cannabis dependence as a distinct clinical entity, this study aims to assess cannabis use and the mental health correlates of cannabis use (including other substance and drug use, depression, anxiety).

The project will interview a sample of over 6000 young adult Australian twins using a structured interview, conducted by trained interviewers and administered via telephone and a self-administered questionnaire. These instruments will assess lifetime history of cannabis and other drug use and other related aspects of substance use and mental health.

This project is a collaboration between principal investigators from the Washington University School of Medicine, St Louis, Missouri, USA (Dr Michael Lynskey), and QIMR (Professor Nick Martin).
