The VAHCS was funded by grants from the Australian National Health and Medical Research Council (NHMRC) and the Australian Government Department of Health and Ageing. The PATH study has been funded by Unit Grant 973302, Program Grant 179805 and Project Grant 157125 from the NHMRC, a grant from the Australian Rotary Health Research Fund and a grant from the Alcohol-Related Medical Research Grant Scheme of the Australian Brewers' Foundation. The ATP data used in the present analyses was funded by grants from the Australian Research Council and the Australian National Health and Medical Research Council. The two later waves were also supported by the Australian Institute of Family Studies. The ATP study is managed by the Australian Institute of Family Studies (AIFS), and is a collaboration between the University of Melbourne, Royal Children's Hospital, and the Australian Institute of Family Studies; further information available at www.aifs.com.au/atp. The CHDS has been funded by grants from the Health Research Council of New Zealand, the National Child Health Research Foundation, the Canterbury Medical Research Foundation and the New Zealand Lottery Grants Board. The present study resulted from a collaboration of Australasian longitudinal studies with an interest in cannabis use and mental health. This collaboration, known as the Cannabis Cohort Research Consortium (CCRC), has been supported by funding from the NHMRC and from the Australian Research Alliance for Children and Youth (ARACY). The CCRC is based at the National Drug and Alcohol Research Centre (NDARC), Sydney, Australia. As one of the leading partners in the ATP since 2002, the AIFS has had a direct role in study design and data collection for the ATP. This support aside, none of the above funding organisations had any role in study design; in the collection, analysis or interpretation of data; in the writing of the report; or in the decision to submit the paper for publication.We thank Kaarin Anstey, Anthony Jorm, Bryan Rodgers, Simon Easteal, Peter Butterworth, Nicolas Cherbuin, Andrew McKinnon, Trish Jacomb, Karen Maxwell and the PATH interviewing team for their contribution to the PATH Through Life Project.
