In 2014 Hall published a review that examined the adverse effects of cannabis. This review included studies from the previous 20 years. He concluded that driving while cannabis-impaired approximately doubles the risk of a car crash. He also concluded that when used regularly in adolescence the risk of school-leaving and "of cognitive impairment and psychoses in adulthood" was doubled. The review reported that about 1 in 11 of regular marijuana users develop dependence. Hall told LiveScience that "The perception that cannabis is a safe drug is a mistaken reaction to a past history of exaggeration of its health risks."Hall was elected Fellow of the Australian Academy of Health and Medical Sciences in 2015.
