Cannabis containing primarily CBD did not impair driving whereas cannabis containing THC, or a THC/CBD combination, precipitated delicate impairment measured at 40 minutes later however not after 4 hours.

These results provide much needed insights into the magnitude and duration of impairment caused by different types of cannabis and can help to guide road-safety policy not just in Australia but around the world”.
Studying the results of cannabis on driving with such precision in a real-world context is extremely necessary.
