im very curious beacuse my eyes turn really really red bloodshot every single time i got a freind of mine that i always smoke with but his eyes never seem to get red it bugs the hell outta me especially when im stoned n im looking at the mirror wondering why they are so red n his are not
Something about THC stimulating blood vessels in your eyes or something... don't quote me though. Also, doesn't always effect everyone.
I think it has something to do with the vessels in your eyes relaxing or something like that. I find that more dry weed makes my eyes more red than usual.
sometimes the smoke will dry ur eyes out, coughing will get them red. but if u drink a bunch of water they dont get that red, but my eyes really dont get red anymore. not like what they used to do, they got real bad when i was new to weed.
my eyes odnt get red if i just smoke a bowl a two.. but if i smoke a shitload my eyes will be reder then hell.
THC has the property of dilating blood vessels, so when the blood vessels in your eye get bigger, they tint them red. It also depends on the strain, some strains get your eyes redder than others. I think this might have to do with different levels of cannabinoids.
