I have gone from younggrandma to just yg. Now,
I am using my real name.
I don't think anyone who knows me will have trouble figuring out who that is!

I have been gone a while dealing with things in my own life. I am back now to help once again. Do not expect answers from me that just tell you what you want to hear. Life is to short for nonsense. :)

I got high... I know, stupid. My eyes were so red I thought I was going to go blind or something. So, why does marijuana make your eyes red? Does anyone know? (link)
From wiki answers...

Marijuana decreases pressure in the eyes and increases blood flow. When this happens, the arteries in the eye-ball expand (due to decreased pressure). These arteries, especially when expanded, are visible in the white portion of the eye and make the eye appear "bloodshot" or red.

This very result (decrease of pressure in the eye) is the primary reason marijuana is used to treat glaucoma. Glaucoma is the condition where there is excessive pressure in the eye. In some patients, the pressure can become so severe that it causes damage to the retinal nerve, ultimately damaging the patient's vision. Marijuana decreases this pressure.

Because it causes blood vessels to slightly contract (enlarge). So, the blood vessels in your eyes contract, causing them to appear more red.
