Anorexia
What is Anorexia? Anorexia is an eating disorder that generally presents itself by severe weight loss, a loss of appetite, a distorted body image, and a fear of gaining weight.[2] These symptoms may also be accompanied by the intense desire to exercise. While anorexia may be the primary condition in some patients, it can also be a side effect of more serious conditions such as cancer or HIV/AIDS.[1]
The part of the brain that translates food consumption into the emotion of pleasure has been found to be underactive in patients with anorexia. This can lead to loss of appetite because the patient no longer has a positive relationship with eating.[4]
Patients may experience anxiety and fear after consuming food.[4] This can cause a patient to avoid food altogether leading to anorexia. Anorexia is the third most common chronic disease among young people.[3]
Cannabis Treatment
The THC compound of cannabis works with the receptors in the human body that control appetite. This interaction aids to increase the appetite in patients so that they consume a healthy amount of nutrients and calories and maintain a healthy weight.[1] In this way, cannabis provides a more painless solution to anorexia than requiring a patient to use a feeding tube.
Along with aiding the appetite in patients, the THC in cannabis also affects the mood of patients. This helps to calm the anxiety and fear some patients associate with eating. THC interacts with the brain to allow the patient to experience the taste of food fully. A study in Belgium found that when patients can fully experience the taste of food, it becomes a more pleasurable experience and the desire to eat increases naturally.[4]
Patients who use cannabis for anorexia have found strains high in THC to be the most effective.[2]

Cachexia (Wasting Syndrome)
What is Cachexia? Patients with cachexia, or Wasting Syndrome, tend to experience a loss of appetite and excessive, unintended weight loss. This weight loss, which can occur even if the patient consumes proper nutrients, is different from malnutrition. Weight loss that is caused by malnutrition tends to be mainly fatty tissue, while weight loss caused by cachexia can be around 50% muscle tissue. This loss of muscle tissue can lead to fatigue and decreased strength. Cachexia is often a secondary condition, resulting from diseases such as cancer, AIDS, heart failure, or advanced chronic obstructive pulmonary disease (COPD).
Cannabis Treatment
Since cachexia is usually found to be a secondary issue, treatment may differ depending on the underlying condition. In general, one of the conventional treatments is an appetite stimulant.[4]
Bodily functions such as appetite, memory, mood, and pain are controlled by the endocannabinoid system. This system is a group of receptors in the brain and central nervous system. One of the primary compounds in cannabis, THC, influences these receptors in order to stimulate appetite and reduce pain. This may help to increase the quality of life in those suffering from cachexia.[4]
Strains of cannabis that contain high levels of THC or THCA have been found to help patients with cachexia most effectively.[4]

Severe, Debilitating, or Chronic Pain
What is Severe, Debilitating, or Chronic Pain? Chronic pain is not usually a primary condition but can be a severe symptom of other injuries or conditions. In the US alone, there are an estimated 38 million adults that experience chronic pain.[1] Chronic pain can be caused by several conditions including cancer, AIDS, sickle cell anemia, and multiple sclerosis. Patients experiencing chronic pain may experience a decreased quality of life due to their inability to function as completely as possible.
Cannabis Treatment
Treatment for chronic pain is dependent on the underlying condition or injury that is causing the pain. The most commonly prescribed treatment for chronic pain is opioids. However, these can cause severe nausea as well as other complications. Cannabis is able to provide almost immediate relief for pain with an extremely low risk of side-effects.[1]
Patients have found that strains of cannabis high in CBD help to minimize chronic pain most effectively.

Severe Nausea
What is Severe Nausea? Severe nausea can be caused by several conditions and treatments including cancer chemotherapy or radiation and AIDS treatment. These treatments, as well as many other medications can cause the constant feeling of a need to vomit. Severe nausea causes patients to lose their desire to eat and can lead to serious conditions including anorexia and wasting syndrome.
Cannabis Treatment
Alleviating nausea is one of the most common uses of medical cannabis.[1] With very few side-effects, cannabis can provide relief from constant nausea that comes with many medications. This assistance helps patients to keep down food and can aid in preventing anorexia as well as wasting syndrome.

Glaucoma
What is Glaucoma? Glaucoma is a condition caused by damage to the optic nerve leading to progressive loss of sight. The most common cause is pressure building up inside of the eyeball. Glaucoma is the second leading cause of blindness. Research completed by the Glaucoma Research Foundation estimates that only half of people with glaucoma are even aware they have it.[3] The symptoms of glaucoma include blurred vision, eye pain, nausea, red eyes, and trouble seeing in the dark. In America alone, it is estimated that over 3 million people have glaucoma.
Cannabis Treatment
While there is currently no cure for glaucoma, cannabis can be used to treat the symptoms and slow down the progress of glaucoma. Multiple research studies have shown that the use of THC can lower the optic pressure by 60-65%.[4] Lower pressure helps to lessen the effects of glaucoma and slow down the loss of vision.
Post-Traumatic Stress Disorder (PTSD)
What is Post-Traumatic Stress Disorder (PTSD)? Post-traumatic stress disorder, commonly referred to as PTSD, is a psychiatric disorder caused by experiencing or witnessing a traumatic event. While PTSD is widely known to affect military veterans, it can occur in anyone that experiences a shocking or dangerous event. The symptoms of PTSD are broken into three categories, re-experiencing, avoidance, and arousal. Re-experiencing symptoms include flashbacks and frightening thoughts and dreams. Avoidance symptoms include isolation from people or events related to the traumatic experience and may also entail the avoiding of thoughts or emotions related to the trauma. Arousal symptoms include insomnia, being easily startled, and angry outbursts.[5] The National Center for PTSD estimates about 7 or 8 out of every 100 people will experience PTSD.[5]
