Further notes: in addition to standard gas grenades, cops use tear gas filled paintballs. Standard strategies of kick it back or douse with water obviously useless. Bring heavy duty respirator masks and goggles. Cloth and sunglasses will not be enough.
Notes on what tear gas feels like
Flu levels of mucus out of nowhere
Tears immediately (obviously)
Burning airway, coughing
Extremely chapped-esque irration sensation on eyes, lips and nose up to an hour later
0/10 experience, would do again if necessary
