Photo: Getty ImagesNew research has shed more light on driving while high, finding that moderate amounts of THC - the main psychoactive compound in cannabis - can cause impairment for up to four hours. Cannabis containing mainly CBD did not impair driving while cannabis containing THC, or a THC/CBD mixture, caused mild impairment measured at 40 minutes later but not after four hours. These results should allow for evidence-based laws and regulation for people receiving medical cannabis."
