Experimental evidence indicates that cannabis impairs the skills important for driving. Perception and attention are greatly affected and various tracking functions are also impaired. Tests on driving simulators showed the biggest impairment caused by cannabis was in perceiving and responding to potentially hazardous situations. Combined with alcohol, sedatives and various other drugs, cannabis heightens their effects on thinking, behaviour, and muscle control.
