Cannabis users often think they are safer when they are under the influence because they drive slower. However, this also means that the driver avoids tasks that require effort, like over taking. It also distorts perception of time and distance so other vehicles seem closer than they really are.

The specific effects of driving on cannabis are:

Slow driving
Avoiding driving tasks that require effort
Affects ability to control the car safely
Increased reaction and decision times
Inaccurate judgement of time and distance
Inability to maintain headway
Poor control of lateral position
Impaired sustained vigilance
