marijuana for nightmares
Many of us have experienced a bad dream, but when someone has intense, reoccurring nightmares, they can act as a sleep disorder of their own. Estimates show that two to eight percent of people have nightmares severe enough to cause sleep issues.

Although cognitive behavior therapy has shown promise as a treatment for nightmares, it can take a considerably long time to see results, and its success may depend on the underlying cause of the nightmares. Most of the medications that are used to treat nightmares come with their own long list of potentially negative side-effects.

Medical marijuana is a safer, potentially more effective alternative. It may work to reduce anxiety, alleviate depression and decrease insomnia. Also, when the underlying cause of nightmares is anti-anxiety or narcotic-based pain medication, medical marijuana may provide an alternative, which in turn removes the cause of the nightmares.

More and more patients are choosing cannabis medicine as a supplement or replacement for their nightmare treatment, and you could, too. In this guide, we’ll give you the information you need to make an informed decision about treating your nightmares with medical marijuana. Keep reading to learn:

Medical Marijuana for Nightmare Relief

When standard nightmare treatments just won’t do the trick, marijuana medicine can tackle many of the underlying causes of nightmares. In fact, it can help relieve most of the causes we mentioned earlier:

  • Stress and anxiety: When used correctly, medical marijuana can reduce anxiety and stress. Sometimes, anxiety can be a side effect of medical cannabis, but if that happens, you just need to adjust your dosage like you would any other medication.
  • Sleep deprivation: As part of marijuana’s calming properties, it also promotes better sleep. It makes it easier to fall asleep when you have insomnia or other sleep issues.
  • Alcohol and drug use: When abuse or addiction cause nightmares, medical marijuana can help you cope with withdrawal symptoms and reduce your dependence. It can relieve hard-to-treat substance abuse disorders like opiate addiction and alcoholism.
  • Medications: Medical cannabis can work as a supplement or replacement for nightmare-causing medications like antidepressants and blood pressure medicine.
  • Trauma: If your nightmares come as a symptom of PTSD, you can reduce nightmares and some of the other issues that the disorder can cause.
  • Parkinson’s disease and other neurodegenerative conditions: When nightmares happen as a result of a condition like Parkinson’s, cannabis medicine can protect your damaged brain cells from further harm.
  • Heart problems: Medical marijuana can reduce blood pressure, potentially reducing the impact of heart issues on your dreams.
  • Mental illness: Marijuana medicine improves mood symptoms and other problems associated with mental illness, including nightmares.

Cannabis Medicine as a Nightmare Suppressant

In addition to relieving health issues that cause nightmares, medicinal marijuana could directly reduce or eliminate your nightmares by impacting your rapid eye movement (REM) sleep. When you sleep at night, your brain and body cycle through different stages that give you important forms of rest. While most of these stages don’t involve REM sleep, REM sleep happens as its own phase. During this period of the sleep cycle, your eyes move rapidly, and you experience dreams.

Evidence suggests that medical marijuana can suppress REM sleep, making you dream less or stop dreaming at all. For people who experience frequent nightmares, removing dreams gets rid of the bad dreams, too.

Medical Marijuana and Nightmares: Clinical Evidence

Medical marijuana has been relied on, and used, for centuries to reduce stress, tension and anxiety. Recent studies that have been done on patients suffering from anxiety or stress have confirmed what numerous cultures have known for centuries — that many patients do report a decrease in anxiety levels with the use of medical marijuana. Conversely, some patients show an increase in anxiety when using medical marijuana. Individual body chemistry may be the key to why some patients actually report an increase in anxiety. For those who experience a decrease in anxiety, medical marijuana may be an alternative to conventional anti-anxiety or anti-depressant medications that are at the root of the patient’s nightmares. When the THC found in marijuana reacts with a brain substance known as anandamide, it has been shown to produce a calming effect throughout the body, thereby reducing anxiety.

Nightmare sufferers who also suffer from insomnia or sleep deprivation may be able to get relief from medical marijuana as well. Because the chemical properties found in marijuana create a calming effect throughout the body, patients may find that sleep comes easier and is interrupted less often by nightmares. For nightmare sufferers who suspect that narcotic-based medications may be contributing to their nightmares, medical marijuana may allow them to reduce the amount of opiate-based medications they are taking. A recent study showed that patients taking opiate-based pain medications were able to reduce their opiate based medication by augmenting their medication with medical marijuana while still experiencing the same degree of pain relief.

A 2009 study by Dr. George Fraser suggested that nabilone, a synthetic cannabinoid, could reduce or eliminate nightmares in PTSD patients. Nabilone works like the components in marijuana, cannabinoids, by activating special receptors in your cells. It relieves common symptoms addressed with medical marijuana like severe nausea and vomiting. But, Dr. Fraser wanted to see if it could impact nightmares after seeing plenty of anecdotal evidence from medical marijuana patients. So, he conducted a chart review of PTSD patients he treated with nabilone. An impressive 72% of his 47 patients reported a total cessation of nightmares or a large reduction in the intensity of their bad dreams.

What Symptoms Caused by Nightmares Can Medicinal Marijuana Treat?

Nightmares can result in health issues that can severely impact your everyday life. Fortunately, medicinal cannabis addresses symptoms caused by nightmares such as:

  • Insomnia: When you have intense nightmares on such a frequent basis, you can experience problems falling asleep or staying asleep. Some patients have trouble getting to sleep because they dread dealing with their nightmares. Cannabis’ relaxing and sedative effects make it easier for patients to fall asleep.
  • Depression: While depression can cause nightmares, the opposite can also happen. The difficulty of dealing with the sleep deprivation, anxiety, fatigue and disturbing dreams associated with nightmares can result in depression. Certain kinds of marijuana medicine improve mood symptoms like depression.
  • Anxiety: The stress caused by nightmares and their resulting symptoms can also trigger anxiety disorders and symptoms. Marijuana’s calming properties can help address this issue.
  • Fatigue: Sativa-based cannabis medicine gives the patient energy, combatting fatigue caused by sleep and mood issues associated with nightmares.

Cannabinoid Science 101: How Do Marijuana Components Work to Relieve My Symptoms?

The cannabis plant contains a veritable pharmacy of compounds that can relieve a wide variety of health problems. You can find at least 85 different compounds called cannabinoids that have unique curative properties. We have the most knowledge about the two major cannabinoids, cannabidiol (CBD) and tetrahydrocannabinol (THC). Both these cannabinoids can work to relieve nightmares. While THC suppresses REM sleep and reduces bad dreams, CBD improves mood and rest.

How to Use Medical Cannabis for Nightmares

If you’re new to medical marijuana, you might think that you can only take it by smoking. But this misconception doesn’t give the versatility of cannabis medicine the credit it deserves. There’s a medication method out there for every kind of patient, whether you want a more traditional medicating experience or prefer unconventional approaches. Medicinal marijuana can come in the form of:

The type of marijuana medicine you choose mainly depends on your personal preferences and lifestyle, but some products will work better for your nightmare symptoms than others. For example, if your issues mainly have to do with falling asleep, you can vape before bed to take advantage of the quick kick-in time. Or, you could use a patch to get a continuous release of cannabis medicine into your system throughout the night. For more help choosing a medication, talk with your doctor or dispensary budtender.

If you like to medicate with marijuana flower or certain other types of medicine, the cannabis strain will factor into your choice. The marijuana plant comes in three different strains, or varieties, that specialize in treating specific symptoms. A medicinal cannabis professional can help you understand the differences among the three, but you should have a basic understanding of them:

  • Indica strains have sedative and calming effects that help you relax, fall asleep and stay asleep. They tend to have higher amounts of CBD, the component that can suppress REM sleep and dreams.
  • Sativa strains can give you energy when nightmares make you tired and lift your mood when they cause depression.
  • Hybrid strains can be a crossbreed of any two strains. Some hybrids combine sativa and indica strains in different ratios that take advantage of both varieties’ effects.

Many strains earn reputations of addressing specific symptoms in particular. For example, White Rhino and Bubba Kush are known for their sedative properties and let you sleep longer.

Side Effects of Cannabis Medicine

Marijuana medicine can cause side effects like any other medication, but it tends to have milder and less dangerous adverse effects than pharmaceuticals. Some strains and dosages have a higher chance of certain side effects than others, but many of them can be resolved by adjusting your cannabis medication. Common side effects of medicinal marijuana include:

Sleep Peacefully With

Take your treatment into your own hands with medical marijuana. Medicinal cannabis’ holistic approach lets your medicine work with your whole body, rather than just treating specific symptoms. If you want to start medical marijuana treatment, follow these simple steps:

  1. Research your state’s medical marijuana laws to determine if your condition qualifies.
  2. Book an appointment with a marijuana doctor in your area.
  3. Receive the required documentation for patients in your state, such as a medical marijuana card and/or recommendation.
  4. Visit a dispensary near you to buy cannabis medicine

Even if your state lets adults over 21 buy and use recreational marijuana, you should still work with a doctor to create a treatment plan. They understand how cannabis medicine works with your body, so they can give you professional advice you can’t find elsewhere.

Nightmares as a Medical Condition or Symptom

Most people have their first nightmares between three and six years of age and start to have fewer nightmares after age 10. Nightmares are healthy and normal as long as they happen occasionally and don’t cause major problems. Harmless nightmare activity involves:

  • Adequate rest regardless of dreams and nightmares
  • Little to no problems with everyday functioning due to nightmares
  • No lasting trauma or mood problems resulting from the nightmares

Meanwhile, you should get medical attention for your nightmares if they cause issues like:

  • Sleep disturbances
  • Distress that makes it difficult to fall back asleep
  • Low energy during the day due to lower quality sleep
  • Problems concentrating, remembering things and functioning during the day
  • Making you dread going to sleep because you have such severe nightmares
  • Persistent anxiety during the day

Even if you don’t feel you have these issues, you should tell your doctor if you have nightmares on a frequent basis. They could have a bigger impact on your sleep quality than you may think.

How to Categorize a Nightmare Disorder

When a doctor diagnoses nightmares, they add certain specifiers that show the frequency and duration of the dreams. The following adjectives are used based on how long you experience frequent nightmares:

  • Acute: One month or less of chronic nightmares
  • Subacute: Between one and six months of chronic nightmares
  • Persistent: Six or more months of chronic nightmares

Once determining how to describe the duration of your nightmare problems, your doctor will then categorize their frequency:

  • Mild: Nightmares happen less than once a week on average
  • Moderate: Nightmares occur more than once a week, but less than once a night
  • Severe: Nightmares happen every night

Nightmare disorders can come in many forms, all of which interfere with the patient’s well-being. But, why do nightmare disorders occur in the first place?

Why Do People Have Severe Nightmares?

Numerous factors can cause you to have severe and frequent nightmares, including:

  • Stress and anxiety: Major changes, problems in life and high-pressure situations can trigger nightmares at night. Feeling anxious increases the risk that you’ll have nightmares at night.
  • Sleep deprivation: Missing out on quality sleep can also raise your chance of nightmares. Sleep disorders can cause you to experience more severe and frequent bad dreams.
  • Alcohol and drug use: Using or withdrawing from alcohol and recreational drugs can give you nightmares.
  • Medications: Even drugs prescribed to you can cause nightmares. Blood pressure medication, antidepressants, beta blockers and other medicines can have this side effect.
  • Trauma: After something traumatic like an accident, abuse or injury, you can have nightmares related to the incident. They can happen as a symptom of post-traumatic stress disorder.
  • Parkinson’s disease and other neurodegenerative conditions: Nightmares could be indicative of lesions in the lower brainstem. This symptom is associated with neurodegenerative diseases like Parkinson’s.
  • Heart problems: Patients with spasmodic chest pain and irregular heartbeats could also face an increased risk of chronic nightmares.
  • Mental illness: Nightmares can happen as a symptom of mental illnesses like depression.
  • Genetics: If you have family members who experience nightmares or certain other sleep issues, you have a higher chance of having frequent nightmares.

Standard Treatments for Nightmares

When nightmares negatively impact your health, you might need medical treatment. The treatment a physician orders depends on the cause of the nightmares, and multiple factors could be at play. Patients with nightmares most commonly receive the following kinds of treatments:

  • Medical treatment for an underlying condition: When you have a health disorder that causes nightmares, your doctor will likely work with you to address it first. By relieving the disorder, you can experience less frequent nightmares.
  • Therapy: When trauma or a mental health condition causes your nightmares, your physician might recommend seeing a therapist. Therapy teaches you to work with your thoughts and feelings so you experience fewer symptoms.
  • Medication: In severe cases, you may be prescribed medication to reduce your nightmares, but this approach happens rarely.
  • Imagery rehearsal therapy: Many patients with PTSD-related nightmares use imagery rehearsal therapy to take control of their nightmare’s narrative. The patient creates their own ending to a recurring nightmare and rehearses it in their mind while they’re awake.

In some cases, your doctor may suggest some lifestyle changes before asking you to go through medical treatment. You could talk about the dream with someone else after you have it or write in a notebook about it. If your nightmares happen due to sleep problems, your doctor might ask you to establish a consistent bedtime routine. Stress-relief activities could also reduce your nightmares if they have to do with anxiety.
