Advice not to operate an automobile is for minimizing risks. It doesn't mean that most would be unable to handle a car, although it could mean that their reaction times would be slower. The standard way to administer ketamine is to give 0,5 mg/kg under 40 minutes. It would in no way be immediately obvious to everyone in, if someone began to receive ketamine or not. At least I couldn't differentiate them at that point.
