I suspect that more than booze was involved here. Since being issued with new testing kit, traffic cops' bookings for Class A and B drugs in drivers' systems are approaching or overtaking those for alcohol - and some of these same sorts of folks would likely react badly to confinement/claustrophobia in an airliner after they've taken a 'recreational' substance before boarding, which is beyond airports' and airlines' control.
The potential for some narcotics to cause paranoid symptoms is well known.
