While it is common knowledge that marijuana can help lower eye pressure it does not mean optometrists will prescribe it! Despite the fact that medical marijuana has not be legalized in Florida it will never be endorsed by eye care professionals in the management of glaucoma because there are other and far superior ways to manage it.
The truth is that marijuana will lower the eye pressure for about 3-4 hours after it is smoked. Patients who have glaucoma need their eye pressure to be maintained a certain level for 24 hours/day. It is also unclear how much it lowers the pressure.
Bottom line: Marijuana is not a effective treatment for glaucoma. Sorry!
