As far as I know, in NJ prohibitions on off duty police drinking while carrying are matters of department policy; specifically, the department may or may not defend the actions of an officer who was found to be intoxicated while carrying.

NJ law does not prohibit those with carry permits from drinking; most who have such permits are retired LEO's (very few are issued carry permits based on the justifiable need standard). So, retired LEO's are free to drink while carrying. However, oddly enough, liquor licensees are required to not serve anyone they know to be armed, by Alcoholic Beverage Control regulation.
