CANNABIS CAMPAIGN QUESTION AND ANSWER

IF CANNABIS USE BECOMES MORE WIDESPREAD, IS AN INCREASE IN TRAFFIC
FATALITIES INEVITABLE?

There is no compelling evidence that cannabis contributes substantially to
traffic accidents and fatalities. At some doses cannabis affects
perceptions and psychomotor performance changes which could impair
driving ability. However, in driving studies, cannabis produces little car
handling impairment consistently less than that produced by low to
moderate doses of alcohol and many legal medications. In contrast to
alcohol, which tends to increase risky driving practices, cannabis tends to
make subjects more cautious. Epidemiological surveys in Canada, Australia
and the United States of drivers in fatal road accidents have found
cannabis in the blood of 311 per cent of dead drivers. However, in 7090
per cent of these cases, alcohol was detected too. It is likely, however,
that cannabis does contribute to bad driving in some individuals,
especially inexperienced cannabis users and inexperienced drivers.
