Driving while feeling bad

This is just insane.

From nj.com: The severe symptoms of a hangover -- piercing headaches, body aches, dry mouth and upset stomach -- should no longer be your only concern after a night of drinking in New Jersey. Now there is the law.

In a ruling that expands the legal meaning of "under the influence," a state appeals court Thursday ruled a hangover is also an impairment -- whether it's from drinking alcohol, taking cocaine or other substances.

The judges, in a 3-0 decision, ruled a Cape May County driver, who had taken cocaine but was not intoxicated when police stopped him, was still a danger to other drivers. While the cocaine was no longer active it was the "proximate cause of his impaired behavior," the judges found.
Simply: drivers who are hung over from using cocaine can be considered impaired even if the drug is no longer in their systems.

If driving with a headache that is induced by having drank to much, or taken cocaine yesterday when is it going to become a crime to simply drive with a headache? You're just as impaired if the headache is caused by bright sun as you are if it was caused by a hangover.

Does New Jersey have some kind of bar exam requirement that requires lawyers be insane?
