Depending on what state you live in, patients may be able to treat many different conditions with medical marijuana or very few. But even in states that allow many different uses for medicinal cannabis, there are still some conditions that are not covered.

Here are seven conditions that marijuana can treat but aren’t currently allowed by law:

1. Impotence

There are both physical and mental causes for impotence, both of which can be solved with marijuana. The right strain can relax a person and get rid of their anxiety related to the issue, and there’s also studies showing that cannabis can help address the physical causes such as hypertension. Although we’re not sure politicians will ever add this to their list.

2. Alopecia Areata

Alopecia is a condition where a person begins losing hair in unpredictable manners. It’s believed to be caused by an autoimmune disorder that attacks hair follicles. Some studies have shown that cannabis use can help prevent the immune system from mistakenly attacking hair follicles, therefore preventing hair loss.

3. Conjunctivitis

Conjunctivitis, more popularly known as pink eye, is a fairly common condition that affects people. Essentially, it’s caused by the inflammation of the tissue inside your eyes. While there aren’t many studies on the topic, it’s believed that the anti-inflammatory properties of CBD can help reduce pink eye.

4. Asthma

The effect of cannabis on treating asthma is somewhat controversial. Asthma is a lung disease that causes a person’s airways to narrow and swell, which causes a shortness of breath. Smoking marijuana, unlike smoking tobacco, actually expands a person’s bronchial passageways, which can make it easier to breath. A 20 year study found that cannabis users with asthma saw improvement over time in lung function without suffering damage. However, some doctors say that smoking anything can cause tissue inflammation and throat irritation, which can be problematic for those with asthma.

5. Various Skin Conditions

There are many studies that show cannabis use can help with various skin conditions. In fact, some states already allow medical marijuana for psoriasis. But there are several others that cannabis can help as well, including dermatitis, pruritus, eczema and more.

6. Endometriosis

Endometriosis is a condition that affects women when the tissue that lines the inside of the uterus begins growing on the outside of it. This causes pain which can often be pretty severe and lead to other problems. A study found that the use of cannabis can not only reduce the pain caused by endometriosis, but can also reduce the tissue growth that causes the condition in the first place.

7. Sleep Apnea

Sleep apnea is a disorder where a person’s breathing becomes interrupted during sleep. This can cause minor problems, such as tiredness during the day, and more serious problems if a person is repeatedly not breathing during the night. Excess serotonin levels in the nervous system are known to exacerbate sleep apnea conditions, and studies have shown that cannabis use can reduce the amount of serotonin in a person’s body, which would help reduce sleep apnea symptoms.
