I have damaged my eye with smoking weed after surgery - this is what i have found on the internet "Vasodilation is a symptom from THC in the blood stream. every cell in your eye is altered in location, shape, or pressure. While healing, this can cause your cornea to heal differently than expected, the cells in your eyes may receive to much, or not enough of what they need to survive and heal " - i know this is what i have done and i have massive headaches ever since, what are long term effects ?
