sorry but your just wrong. red eye is not caused by dehydration. THC is a vasodilator, which means that it causes the smooth muscle walls of your blood vessels to relax, resulting in dilation(expansion) of the blood vessels in your eyes and throughout the body. but yeah i agree that its better to put eyedrops in before you smoke or immediately after. it sucks when you have to be somewhere and you have to scramble to put drops in and your eyedrops arent working fast enough.
