The consumption of **drugs** negatively affects driving ability and, in particular, **increases reaction time**. This means that a person takes longer to respond to situations on the road, which is dangerous.

- **All drugs** are dangerous for driving. None improve reaction time.
- **Cannabis**: requires more time to react and can cause drowsiness.
- **Cocaine**: although it may give a false sense of alertness, it actually causes impulsivity and loss of concentration, worsening response ability.
- **Ecstasy and LSD**: cause hallucinations and loss of concentration, severely affecting reaction ability.
- **Amphetamines**: can delay fatigue, but once the effect wears off, tiredness can appear suddenly, increasing the risk of falling asleep at the wheel.

Additionally, drug consumption is a factor that causes a person to take longer to react, along with others such as fatigue, sleepiness, and alcohol consumption. Therefore, it is incorrect to think that any drug could improve reaction time when driving.
