Driving under the influence of **alcohol** or **drugs** is extremely dangerous, even in small amounts. Here we explain why:

- **Alcohol**: It affects the brain and vision, which can alter perception and reaction time. Even when consumed in small amounts, alcohol is responsible for many traffic accidents.

- **Drugs**: All drugs are dangerous when driving. For example:
- **Cannabis**: It can alter the perception of colors and distances, decrease concentration, and increase reaction time.
- **Cocaine**: It can make the driver more impulsive and lose the sense of danger.
- **Ecstasy**: It can cause hallucinations and increase sensitivity to light.
- **LSD**: It can provoke hallucinations and aggressive reactions.
- **Amphetamines**: They can lead to impulsive behaviors and a false sense of alertness, followed by sudden fatigue.

- **Risk of accidents**: One in ten people who die in traffic accidents had consumed drugs. This underscores the danger these substances pose when driving.

In summary, both alcohol and drugs negatively affect the skills necessary to drive safely, even in small amounts. Therefore, it is crucial to avoid their consumption before getting behind the wheel.
