Driving under the influence of drugs is extremely dangerous and can affect driving skills in a number of ways.
Cannabis users often think they are safer when they are under the influence because they drive more slowly. However, cannabis slows reaction and decision times. It can also distort perception of time and distance, and result in poorer concentration and control of the vehicle.
Cocaine leads to a sense of over-confidence and this is reflected in user’s driving style. Users typically perform higher risk, more aggressive manoeuvres at greater speeds.
Ecstasy (MDMA) is extremely dangerous to drive on because it results in distorted vision, heightened perception of sounds, altered perception and judgment of risks and an over-confident driving attitude.
During the phase whilst the effects of any illegal drugs are wearing off the user may feel fatigued, affecting concentration levels.
Driving in any of these conditions is a bad idea – not just for the driver but for their passengers and other road users.
