Cocaine is a stimulant that, although it can give a false sense of alertness, **significantly decreases the driver's ability to concentrate**. This drug negatively affects perception, reaction time and the ability to make safe decisions at the wheel. For these reasons, driving under the effects of cocaine is extremely dangerous and prohibited by law.
