The reason your eyes turn red (or get redder than normal) after you smoke, eat, or insufflate anything with Delta 9-tetrahydrocannabinol and/or any active Cannabinoids is, when the brain's receptors encounter these chemicals it automatically produces counter-chemicals that slightly increase the heart rate and relieve pressure on the capillaries throughout your body. Ergo, blood flow is less impeded and the heart is pumping more and harder than usual. In turn, the capillaries in your eyes, ears, nose, and throat are running at nearly optimum efficiency. The eyes are merely the most visibly noticeable change (next time you get stoned take a second to look out how your ears turn red as well). The best way to treat red eyes is usually some sort of ophthalmic sympathomimetic agent such as Visine Advanced Relief.
