Research and Expertise
Over the last seven years or so, a major line of my research program has focused on estimating the impacts of cannabis use on human health. This line of research has produced a series of studies assessing the relation between cannabis use (or cannabis-use disorders) and a range of health outcomes, such as:
(1) Persistent psychotic syndromes (Callaghan, et al., 2011);
(2) Mortality patterns (Callaghan, et al., 2012);
(3) Fatal and non-fatal motor vehicle collisions (Callaghan, et al., 2013);
(4) Development of cancer in humans (Callaghan, et al., 2017);
(5) Lung cancer (Callaghan et al., 2013); and
(6) Testicular cancer (Callaghan, et al., 2017).
Ongoing and future work will assess the impacts of Canada’s cannabis legalization on a range of outcomes, including fatal and non-fatal motor vehicle collision injuries, cannabis-related criminal incidents, cannabis-use disorders and cannabis poisoning, and transient and persistent psychotic syndromes.
My research efforts also include examination of the historical roots of the concept of mindfulness, Buddhist influences on mindfulness theory and practice, and the efficacy of mindfulness-based interventions on health.
