“[N]o research has found that marijuana is anywhere near as effective as legal glaucoma medications…
The American Academy of Ophthalmology, among other authoritative sources, says the risky side effects of marijuana (such as lowered blood pressure, increased heart rate, poor pregnancy outcomes, poor motor coordination, impaired memory and increased risk of cancer and emphysema) far outweigh any benefit.
Popular opinion persistently exaggerates the benefit of marijuana for glaucoma.
This is unfortunate, because people who use marijuana instead of their prescribed glaucoma medication run a big risk of having irreversible vision loss.”Jan. 2012
