Marijuana and the Eyes. Marijuana has a few key effects on the eyes. One of the most noticeable occurs shortly after smoking the drug: redness of eyes. THC in marijuana lowers blood pressure which dilates the blood vessels and increases blood flow throughout the body.
If it's your first time you may not fully feel the effects of the high. For some reason unbeknownst to me, many people don't get high the first time or two. How long a high lasts depends on a number of things. i.e. quality of marijuana, amount smoked, and tolerance. Red eyes result from your eyes being dry. It usually lasts as long as the high which can be anywhere from 45 mins to 3 hours.
