Smoking marijuana lowers the eye pressure. But the effect of smoking marijuana lasts only about two hours or so. Therefore, the marijuana patient must smoke every two hours or so to maintain a low intraocular pressure. Doing the math, this would require 12 joints. Yes, if it takes half a joint to accomplish the effect, then the glaucoma patient would require 12 half-joints or 6 full joints per day, every day.
But, this depends on the amount of THC in the marijuana and the amount of marijuana per joint. And I am not aware of one single study which calculates how much of either is necessary.
With a patient's eyesight at stake, I don't understand why people even consider this type of treatment.
But, but I thought the effects of marijuana lasted for days, not just two hours.
Gee, if you are right then the pilot of the plane that crashed could have smoked pot a week or more before the crash and still tested positive for pot and the pot would have had no effect on him.
You make a strong argument for my side, RP. Thanks for pitching in and helping.
