smoking with throat conditions is a hard trade-off. either bask in the euphoria (and sometimes even clearing the phlegm) of the nasal cavities being caressed by THC, whilst slowing down the process of throat healing, and even contributing to the mucus level while most likely further aggrivating it by some coughing while smoking.

oh, by the way... most will recommend bong usage while battling a throat condition. cooled water is preferable.
