Microdosing THC for Glaucoma

Dec 20, 2022The nama Team

Microdosing THC has been proposed as an alternative treatment for glaucoma due to its therapeutic effects. For decades, glaucoma medications have been the only way to control the condition, but patients suffering from it report an increasing number of unwanted side effects.

Microdosing THC for Glaucoma

Emerging research continues to shed light on the benefits of microdosing cannabis for a range of conditions, including glaucoma.

In the 1970s, researchers discovered that cannabis could help glaucoma sufferers by lowering pressure in the eye. This sparked ongoing interest in the medical benefits of cannabis for treating glaucoma.

Understanding Glaucoma

Glaucoma is a chronic condition caused by the damage to the optic nerve that connects your eye to the brain. The damage is usually caused by fluid that builds up in the front part of the eye, increasing intraocular pressure at the same time. This makes your field of vision shrink and peripheral vision darken, impairing your vision entirely. If not diagnosed and treated early, glaucoma often leads to vision loss.

This complex eye condition affects people of all ages, but senior citizens seem to be the most susceptible. Glaucoma is the second leading cause of blindness in people over the age of 60.

Glaucoma can often and suddenly develop symptoms like:

  • Intense eye pain
  • Nausea and vomiting
  • Red eyes and tenderness around the eyes
  • Headaches
  • Blurred vision


Benefits of Microdosing THC

According to research, effects of tetrahydrocannabinol (THC) seem to be greater at low doses. As one study found, higher doses of THC do very little to alleviate pain or discomfort. The results of higher THC doses were, in fact, opposite—they seem to exacerbate chronic pain instead of providing relief.

2020 study aimed to test the analgesic effects, cognitive performance, and safety of microdosing Delta 9 THC to alleviate chronic pain. Participants of the study were given a single dose of one milligram of THC. Pain was significantly decreased without any psychoactive effects.

different study focused on the use of a synthetic cannabinoid called Nabilone in treating PTSD. According to the results of the study, low doses of Nabilone (four milligrams) helped alleviate symptoms of posttraumatic stress disorder, such as insomnia and chronic pain.

Some of the reported benefits of microdosing cannabis also include alleviating symptoms of:

  • Inflammation: cannabis microdoses can treat conditions like arthritis and fibromyalgia due to its anti-inflammatory properties.
  • Seizures and muscle spasms
  • Anxiety disorders
  • Dementia: microdosing THC for dementia seems to prevent the progression of neurodegenerative diseases such as Alzheimer’s.
  • Cardiovascular conditions: low doses of cannabis potentially reduce blood pressure and inflammation.
  • Crohn’s disease
  • Addiction: microdosed cannabis is believed to ease withdrawal symptoms in people struggling with addiction.


Cannabis users also experience that low doses of THC help with sleep. Our sleep gummies with melatonin are a perfect addition to your nighttime routine. They combine the benefits of cannabidiol (CBD) and hemp-derived Delta 9 THC to promote your well-deserved eight-hour trip to slumberland.

Microdosing edibles help with migraines, as well. Many people struggling with chronic migraines have experienced a reduction in pain after starting microdosing marijuana on a regular basis.

Cannabis consumption at low doses has also proved beneficial in:

  • Stimulating appetite
  • Nausea relief from chemotherapy with cancer patients
  • Improving mood, focus, and concentration
  • Providing stress relief
  • Alleviating symptoms of posttraumatic stress disorder (PTSD)
  • Alleviating symptoms of attention deficit hyperactivity disorder (ADHD)
  • Glaucoma


The safest and most effective way of microdosing THC is via edibles. Methods like sublinguals, vapes, and smoking are risky when it comes to dosage control—you can never know for sure how much you have taken.

Our Delta 9 gummies offer exact concentrations of cannabis extracts in every gummy. They bring out all the beneficial properties of low THC doses and CBD for the full spectrum CBD effect.

THC and Glaucoma

Increased intraocular pressure damages the optic nerve. Cannabis users believe that microdoses of THC is an effective tool in lowering IOP and battling glaucoma. Studies conducted on animals suggest that THC might promote blood flow to the eye and have neuroprotective effects by treating and preventing nerve damage.

Intraocular Pressure, Glaucoma, and THC

Intraocular pressure (IOP) is said to be the most important risk factor for glaucoma. Hypertension is a typical starting point for glaucoma and elevated IOP—high blood pressure increases eye pressure, which in turn elevates intraocular pressure. High IOP restricts blood blow to the eye, damaging the optic nerve behind it.

Excessively high IOP can lead to vision loss—damage to the optic nerve cannot be reversed. If glaucoma is left untreated and IOP not lowered, both central and peripheral vision suffer and are eventually lost.

recent study on THC and CBD indicates that the former helps regulate intraocular pressure, while the latter does not. Low doses of THC seem to lower IOP, while even at low doses, CBD doesn’t seem to decrease eye pressure.

One study suggests that low doses of THC can lower intraocular pressure by up to 40%. The results involved several consumption methods—smoking cannabis, inhaling, and cannabis edibles.

Other evidence shows that THC acts as a neuroprotectant agent by increasing blood flow to the optic nerve. In this study, healthy human participants were administered a low dose of dronabinol, a synthetic cannabinoid derived from THC. There was a significant improvement in the condition of the optic nerve and the subjects experienced no psychoactive effects normally associated with THC.

How Much THC is Needed to Fight Glaucoma?

While THC does seem to slow the progression of the disease, it does not reverse the damage to the optic nerve caused by open-angle glaucoma.

Because the pressure-lowering effects of THC are temporary, it is estimated that maintaining optimal IOP levels would require an amount equal to eight to ten marijuana cigarettes. Consuming THC at higher doses involves certain risks associated with significant psychoactive and cardio-pulmonary side effects.

More research is needed to explore the long-lasting effects of medical marijuana on glaucoma and other eye conditions.


Is THC Legal?

Delta 9 THC is federally legal under the 2018 Farm Bill if the Delta 9 is hemp-derived and does not exceed 0.3% by dry weight. Our Delta 9 THC gummies are legal in 48 states with the exception of Idaho and Kansas.

To make sure your purchase is legal in your state, read our state-by-state guide to Delta 9 legality.

THC gummies are nama CBD’s best vegan hemp-derived edibles with Delta 9 THC. Our Bliss Gummies are packed with an equal ratio of THC to CBD (5mg each). They are excellent for coping with stress and anxiety and for lowering eye pressure.

Sativa or Indica for Glaucoma?

Sativas are known for their ‘head high,’ an energizing effect that can alleviate stress and symptoms of anxiety while increasing focus and concentration.

Indica strains are associated with full-body effects—they induce deep relaxation and help with sleep. Many people suffering from glaucoma experience elevated intraocular pressure at night, making indica-dominant strains perfect for nighttime use.

Our hybrid blends marry the benefits of sativa and indica for the most optimal therapeutic effect. Our Energy Gummies contain low doses of hemp-derived Delta 9 THC, only 2.5 mg per gummy. The sativa side of these yummy gummies will provide pain relief and IOP decrease, while a kick of indica will induce deep relaxation.


Can Delta 8 Treat Glaucoma?

Delta-8-tetrahydrocannabinol (Delta 8 THC) is another type of THC compound found in the cannabis plant in much smaller quantities than Delta 9. It produces milder euphoric effects than Delta 9, but has plenty of medical benefits—stimulating appetite, inducing relaxation, anti-anxiety properties, and treating chronic pain.

Some evidence shows that Delta 8 can potentially lower intraocular pressure. Thirty-two different cannabinoids were examined for their ability to decrease IOP in animal subjects. Out of the thirty-two tested, Delta 9 and Delta 8 derivatives were the most effective.

Delta 8 is mostly associated with pain relief and inducing relaxation, according to a study on the differences between Delta 8 and Delta 9 THC. Due to pertinent chronic pain caused by optic nerve damage, Delta 8 THC might be a viable solution to treat glaucoma symptoms.

Aside from pain relief, Delta 8 could also alleviate the feelings of nausea and vomiting. Research was conducted on the role of Delta 8 as a nausea treatment in pediatric oncology patients. The findings suggest that small doses of Delta 8 THC were able to fight off nausea and vomiting without experiencing psychoactive effects.

Our Elevate Delta 8 Gummies can help reduce IOP and alleviate pain caused by damaged optic nerves. Each vegan gummy contains 12.5 mg of hemp-derived Delta 8 THC and is bursting with exotic flavor!

Delta 8 is derived from hemp and contains less than 0.3% of THC by dry weight. This means that Delta 8 THC is federally legal in the US, as compliant with the Farm Bill. Despite federal legality, Delta 8 remains illegal in fourteen US states:

  • Alaska
  • Arkansas
  • Arizona
  • Colorado
  • Delaware
  • Iowa
  • Idaho
  • Kentucky
  • Montana
  • Mississippi
  • New York
  • Rhode Island

Microdosing THC for Glaucoma FAQ

So far, the clinical trials and some anecdotal evidence have shown that CBD might raise the pressure to the optic nerve. Medical experts agree that lowering the intraocular pressure is the best treatment for glaucoma. However, THC seems to be doing a better job as a pressure-lowering agent than CBD.

Cannabidiol (CBD) is a powerful cannabinoid found in the cannabis plant. It has many benefits on our mental and physical health, but it seems that CBD does not help with glaucoma.

According to a study on the effects of CBD and THC on ocular pressure, low doses of cannabidiol didn’t seem to offer any improvements. It was shown that higher doses of CBD (40mg) slightly elevated intraocular pressure. In contrast, five milligrams of Delta 9 THC successfully treated elevated intraocular pressure, despite the temporary effects.

2018 study shows a bit more surprising results—CBD can actually increase the pressure inside the eye of mice. These findings seem to suggest that CBD may worsen glaucoma.

CBD has a plethora of beneficial effects that might mitigate some glaucoma symptoms. A very common symptom of damage to the optic nerve is pain. One study published in 2015 pertains to the use of medical marijuana, more specifically CBD, in chronic pain treatment.

A lot of glaucoma symptoms—nausea, blurred vision, eye redness, and allergies—may also originate from the excessive use of glaucoma medications. The anti-inflammatory and soothing properties of cannabidiol seem to help alleviate nausea. The results of a double-blind, placebo-controlled study showed the efficacy of CBD in treating chemotherapy-related nausea.

CBD and THC have different chemical compositions and effects on our body. For more information, read our guide to the differences between THC and CBD.

Cannabigerol (CBG) is a minor cannabinoid found in the cannabis plant. Some studies suggest that it might be a great way to treat glaucoma, as it can potentially reduce ocular pressure.

Dryness of eyes is one of the most common side effects of smoking weed. The same goes for cannabis edibles, as cannabinoids like Delta 9 THC, CBD, and Delta 8 THC seem to cause dry eyes. Scientists still don’t know the exact reason why this happens, but 2020 research indicates that THC regulates tearing canals via interactions with the body’s CB1 and CB2 receptors.

Smoking cannabis is even worse for dry eyes as smoke causes additional irritation. That’s why we recommend microdosing THC in edibles, rather than smoking or vaping cannabis.

The time needed for cannabis microdoses to kick in depends largely on the method of consumption.

With marijuana cigarettes you can feel the effects quickly, from five to 15 minutes. Smoking cannabis hits your bloodstream straight from the lungs. Due to risks associated with inhaled toxins that can cause lung cancer, marijuana cigarettes are the unhealthiest method of consuming.

Drinking THC beverages is a similarly quick method of consumption. THC is absorbed through the digestive system and from there hits the bloodstream. With our THC Buzz Drops, you should feel the effects after 15 minutes.

Sublinguals are a very common form of THC. You take them by holding sublinguals in your mouth, preferably under your tongue, for a minute or so, until THC is absorbed. Overconsumption is common with sublinguals and oil concentrates, as you can never know the exact dosage you’ve taken. Plus, they really don’t taste that good.

Edibles are the safest, healthiest, and most efficient way of microdosing cannabis. Because they need to pass through the digestive system, it takes time to feel the effects of THC—anywhere from 30 minutes to an hour. In fact, edibles have longer-lasting effects than smoking, vaping, or oil concentrates.

Our Relax Plus Gummies are super fast acting; in only 15 minutes, you can feel enhanced relaxation and a light buzz.

When Delta 8 THC is consumed in large quantities. In contrast, microdosing edibles is a safe and effective way to enjoy the benefits of cannabis, including Delta 8 products, without side effects normally associated with weed.

Red eyes and dry eyes seem to go hand-in-hand—if your eyes are dry and irritated, they are likely to get red. However, these side effects of cannabis consumption are fairly harmless for the average person.

If you live in a state where medical marijuana is legal and you have a medical marijuana card, you can buy Delta 9 THC products at a cannabis dispensary near you.

If you don't have a medical marijuana card, don't live in a state where marijuana is legal, or don't want to drive to a Mary Jane dispensary, you can get our Delta 9 edibles delivered right to your door. Our fruit-flavored edibles are the ideal way to microdose Delta 9!

The entourage effect is a theory that cannabinoids can work together to enhance each other’s benefits. We at nama CBD know about the great potential CBD and THC have when combined. That’s why we made full spectrum gummies that contain CBD, THC, and other cannabinoids for the complete entourage effect.

One way to reap the benefits of the entourage effect is to enjoy hemp Euphoria Gummies. These fruit-packed vegan gummies present a unique blend of terpene rich hemp extract and an equal ratio of CBD to THC. Perfect for that uplifting experience.

You will hardly be able to feel the entourage effect at work. The entourage effect refers to the longer-term benefits you get from combining multiple cannabinoids, as opposed to any immediate psychological effect you might notice.

The best way to start feeling the benefits of the entourage effect is after at least a month of continual use of cannabis microdosing products. If you experience improvement in mood and focus, if you sleep better or feel much less stressed out or anxious, congratulations—you’re experiencing the entourage effect.
