19. It Helps Treat Glaucoma
It’s a well established medical fact that cannabis can help treat the symptoms of glaucoma.
And the reason why has everything to do with cannabis’s effects on our blood vessels.
When you smoke weed, your blood vessels dilate. That means they get bigger, and this in turn allows blood to flow more freely.
One of the things this increased blood flow does is relieve the painful pressure that builds up in the eyes of glaucoma patients.
Scientists have found that smoking weed can decrease intraocular pressure by as much as 25%.
