Weed has been used in the medical field for many years to treat a variety of conditions, from chronic pain to chemotherapy-induced nausea. One condition that has recently gained attention is glaucoma—an eye disease caused by increased pressure inside the eyeball that often leads to vision loss and blindness if left untreated. But does weed really help with glaucoma? In this blog post, we’ll take an in-depth look at the science behind using weed as a treatment for glaucoma.

What is Glaucoma and What are the Symptoms?

Glaucoma is an eye condition that results in damage to the optic nerve due to high intraocular pressure. It is one of the leading causes of blindness in people over 60 years of age. Glaucoma can develop slowly over time without any noticeable symptoms, making it difficult for an individual to detect any changes in their vision until the late stages of the disease.

Common symptoms of glaucoma include reduced peripheral or side vision, tunnel vision, difficulty seeing at night, halos around lights, eye redness and irritation, and pain in and around the eyes. In advanced stages of glaucoma, individuals may experience significant vision loss or even total blindness. Early diagnosis and treatment are vital for preventing permanent visual impairment or blindness resulting from glaucoma.

The exact cause of glaucoma is unknown but it is believed to be related to elevated intraocular pressure caused by a buildup of fluid within the eye, which can damage the optic nerve. Risk factors for developing glaucoma include old age, having a family history of the disease, being of African American descent, having diabetes, having nearsightedness or farsightedness, and taking certain medications such as corticosteroids.

Benefits of Using Cannabis to Treat Glaucoma

Studies have found that medical marijuana can be an effective treatment for glaucoma. The active chemical components of cannabis, including tetrahydrocannabinol (THC) and cannabidiol (CBD), are believed to reduce intraocular pressure (IOP). Research has also found that THC may reduce retinal ganglion cell death, which is responsible for some cases of glaucoma.

A 2004 study published in the British Journal of Ophthalmology concluded that using cannabis-based medicines were safe and effective at reducing IOP in those with glaucoma. Studies have also shown that using cannabis as part of a comprehensive treatment plan can help improve quality of life by relieving glaucoma symptoms such as pain and nausea.

Further research is needed to understand the full effects of medical marijuana on glaucoma, but current evidence suggests it may be beneficial for reducing IOP and other symptoms associated with the condition.

Potential Side Effects of Using Marijuana for Glaucoma

While marijuana can potentially reduce intraocular pressure in some glaucoma patients, there are potential side effects that must be taken into consideration. Studies have found that the short-term use of cannabis can lead to increased heart rate, anxiety, impaired cognitive ability, and memory problems. Long-term use of cannabis has been linked to an increase in one’s risk of developing mental health issues due to a decrease in dopamine production. Additionally, regular use of marijuana may cause changes in blood flow to the optic nerve.

The most common side effect of cannabis use is red eyes. This is caused by increased blood flow to the eyes, which results in redness and irritation. It usually lasts a few hours and can be managed with artificial tears or lubricating eye drops. Other symptoms may include nausea, fatigue, and increased sensitivity to light or sound.

Physically, regular marijuana use has been linked to an increased risk of respiratory illness, chronic bronchitis, and decreased lung function. Additionally, it can also lead to poor coordination and an increased risk of falls, as well as a decreased ability to drive safely.

Psychologically, regular marijuana use can lead to mood swings, depression, and anxiety. In addition, cognitive impairments may persist beyond the period of active use. It is important for individuals considering using marijuana for glaucoma treatment to discuss their medical history with a qualified doctor and weigh the risks against potential benefits.


In conclusion, marijuana has been found to be an effective treatment for glaucoma. While it’s not a cure-all and should only be used after consulting with your doctor, cannabis can provide relief from the pain and pressure of this chronic condition. However, more research is needed in order to understand how different forms of weed may impact different patients.

If you or someone you know suffers from glaucoma and are considering using cannabis as part of their treatment plan, make sure to speak with a healthcare professional beforehand. With the right information and guidance, medicinal marijuana could help improve the quality of life for those who suffer from glaucoma.
