Marijuana Works As a Treatment for Glaucoma, But…
Let’s get this out of the way.
Delta-9-tetrahydrocannabinoid, the active compound in marijuana, reduces the production of fluid within the eye (known as the aqueous fluid).[1] The problem, however, is that it only works for a few hours during the time someone is “high”[2]. Among those people I know who enjoy the feeling of being “high I doubt any of them would want to spend every waking hour of their lives in that state of mind. Even if they did want such a thing it just wouldn’t be practical.
There is also the challenge of standardizing marijuana treatment. Different strains of marijuana vary in their concentration of delta-9-tetrahydrocannabinoid. Additionally, smoking a joint or taking a hit from a bong does not produce a “metered dose” or consistent amount of the active ingredient. Finally, smoking any plant-based material can destroy lung tissue and increase the risk of developing (and dying from) lung cancer.
So, does marijuana work to lower the IOP? Yes. Is it a practical treatment option? No.
