TRUE – Marijuana users often have very bloodshot eyes because marijuana is a vasodilator.[2] It lowers your blood pressure which causes the capillaries in your eyes to relax and increases the blood flow to those vessels. To counter this effect, users often use eye drops specially formulated for redness which decreases the size of the capillaries in the eyes to make the bloodshot appearance go away. If you note your teen using a lot of eye drops for no apparent reason or you find bottles of eye drops and don’t know why, he or she may be using marijuana.
