For the approximately 400,000 Canadians that suffer from Glaucoma, cannabis could provide great relief.
Glaucoma is caused by pressure in the eye including intraocular pressure which is the fluid pressure in the eye. This damages the ocular nerve which can lead to blindness. Many suffer from glaucoma as they age, and currently, there is no cure. However, there are treatments that can help and cannabis is among them.
Since the 1970’s, there have been studies conducted on the effectiveness of cannabis as a glaucoma treatment. One such study called ‘Marihuana Smoking and Intraocular Pressure’, found that cannabis use lowered intraocular pressure by 25-30%. The reduced pressure would be reduced for up to four hours after consumption.
High THC strains were particularly effective. More recently, a study from 2018 found that cannabis significantly lowered pressure in the eyes. It concluded that “Marijuana is an effective ocular hypotensive agent.”
So as medical research continues using medical the evidence is showing that cannabis can fend off damage to the ocular nerve. Though only effective for about four hours after use, it could still be a valuable element to glaucoma treatment.
