"Engineer's defense to his third DWI charge was that he had been working with chemicals in a poorly ventilated lab that put him in a 'neurotoxic state' Just as being slipped a spiked drink at a party is no defense to driving while intoxicated, neither is exposure to mind-impairing chemicals, a New Jersey appeals court held on Monday. Calling drunken driving an absolute-liability offense, the Appellate Division said trial courts shouldn't be burdened with having to sort out complicated pretextual defenses, lest the preventive purpose of the DWI statute be defeated."
