Can I Get a Michigan Medical Marijuana Card for Glaucoma?

Yes — glaucoma qualifies under the Michigan Medical Marihuana Program

Glaucoma is one of the original qualifying conditions for medical marijuana in Michigan and most other states. Patients with diagnosed glaucoma may use medical cannabis as part of a broader treatment plan.

Common symptoms

• Increased intraocular pressure
• Vision loss (peripheral first)
• Halos around lights
• Eye pain or pressure

How medical cannabis may help

THC has been documented to lower intraocular pressure (IOP) — the primary modifiable risk factor in glaucoma. Effects last 3–4 hours, requiring frequent dosing for sustained IOP reduction. Cannabis is generally considered an adjunct, not a replacement, for first-line glaucoma medications.

Evidence base

Research on THC and IOP dates to the 1970s. While the IOP-lowering effect is documented, the American Academy of Ophthalmology does not recommend marijuana for glaucoma treatment, citing the short duration of effect (3–4 hours requiring frequent dosing), the large daily doses needed, side effects on mood and lung health, and potential reduction in blood flow to the optic nerve. Patients should continue FDA-approved glaucoma medications under the care of an ophthalmologist.

Michigan certification requirements

A glaucoma diagnosis from an ophthalmologist or optometrist is helpful documentation. Bring or describe your IOP measurements and current treatment regimen during the consultation.
