What is the legal amount of recreational drugs a driver can have in their system?

The legal amount of recreational drugs a driver can have in their system is none. This means that for the purposes of driving, any detectable amount of recreational drugs is considered illegal, regardless of whether they might have a therapeutic effect or not. The law is designed to ensure that drivers are unimpaired while operating a vehicle, as the influence of drugs can significantly diminish a person's ability to drive safely.

To maintain public safety on the roads, law enforcement agencies adopt a zero-tolerance policy for recreational drugs in a driver’s system. This is aligned with the understanding that impairment caused by drugs is dangerous and can lead to accidents. Therefore, even if an individual believes they can drive safely while under the influence of recreational substances, the law does not permit this.
