Due to cannabis’ possessing over 400 different chemical components, many of whose potential has not been fully researched, the plant is known for being able to aid in the treatment of multiple conditions and diseases. One of the more common conditions that cannabis is used to treat is glaucoma, a disease of the eyes whose symptoms include an intraocular pressure increase that has been shown to cause blindness. The blindness is usually a result of the pressure causing cataracts to accelerate in growth much faster than normal.
While shown to not have an increase in effect over conventional treatments and drugs, cannabis still possesses the capability to reduce the intraocular pressure in patients with primary open-angle glaucoma, or POAG. Conducted over forty years ago, several studies concluded that patients who used cannabis to treat their glaucoma were able to experience a lowered intraocular pressure for roughly three to four hours, with the only noticeable side effect being a sense of euphoria.
