During the inhale or exhale process of smoking a bong or other devices, a trap door occurs when the flow of air is stopped abruptly by a cough which constricts the wind pipe to the lung. This traps the smoke inside the lungs and causes extended exposure, resulting in temporary distress to the user's throat and/or lungs.
