The results from a study of different doses of cannabis and the
influence on driving and driving related skills are reported. The study
required participants who were male, drivers and regular cannabis users
to undertake a variety of different tasks.
The study concludes that though cannabis does have an effect on driving
ability, that alcohol is much worse, and that marijuana users notice
their impairment and compensate by driving slower and more carefully.
