cannabis for migraine

Cannabis for migraine has garnered attention as an alternative therapy for the debilitating headaches affecting millions globally. These headaches, characterized by intense pain, nausea, and sensitivity to light and sound, often prove resistant to traditional treatments such as NSAIDs and triptans, which can be ineffective or carry notable side effects. Recent years have witnessed increasing interest in cannabis for migraine relief, prompting exploration into its scientific basis, efficacy, potential risks, and legal implications.

Migraines afflict millions worldwide, causing debilitating pain and disrupting daily life. Traditional treatments offer relief to some, but many sufferers seek alternative solutions. In recent years, cannabis has emerged as a controversial yet potentially effective option for migraine relief. This article delves into the scientific research surrounding cannabis and its potential role in alleviating migraines.

What is Migraine?

Nausea, vomiting, sensitivity to light and sound, and other symptoms define migraine as a distinct clinical illness rather than just a kind of headache.

Nevertheless, migraine is the second most prevalent neurological illness worldwide and the primary source of disability in those under 50. It is projected that 20.5% of women and 9.6% of men in the U.S. suffer from migraines. Worldwide, over 1 billion individuals are affected by migraines.

A migraine headache is characterized by one-sidedness and pulsating pain; this kind of headache is known as a migraine. A migraine involving aura is a headache disorder characterized by a cluster of symptoms thought to originate in the brain. Aura symptoms often begin 20-30 minutes before the onset of a headache.

What Are The Symptoms of Migraine?

Headaches are often the first sign of a migraine. Words like “pounding” or “throbbing” often express pain. It may start as a slight ache and then progress to pulsating pain that is light, moderate, or intense. A mild to severe headache can worsen if you don’t have it checked out. It’s possible to have pain that originates in different parts of your skull, moves from side to side, or seems to radiate throughout your whole head. Pain may develop in various locations, including the sinuses, jaw, neck, and area surrounding the eye or temple.

Migraine headaches also cause the following symptoms:

  • Irritation by exposure to bright or loud environments or strong scents
  • Discomfort and discomfort in the abdomen, nausea, and vomiting
  • Reduced hunger
  • Extreme heat (sweat)
  • White or very light-coloured skin
  • Intense wooziness and hazy perception
  • Scalp, that’s easy to hurt
  • Diarrhea
  • Fever

What Are The Causes Of Migraine?


Migraine headaches are a complex and poorly understood origin. Specific nerves within your blood vessels transmit pain receptors to your brain, causing headaches. This triggers the release of inflammatory molecules into the head’s blood vessels and nerves. Unfortunately, no one can explain why your nerves are acting like that.

Many things may set off a migraine episode. Common precipitants include:

  • Psychological strain: Migraine headaches are often triggered by emotional stress. Some chemicals located in the brain deal with stressful situations. When these substances are released, they might trigger migraine symptoms.
  • Intolerance to certain food additives and preservatives: Up to 30 percent of migraines may be brought on by eating or drinking certain things, such as alcoholic drinks and food additives like nitrates.
  • Caffeine: When the body’s caffeine supply suddenly runs out, headaches may result from either overuse or withdrawal. In addition, when you don’t obtain your daily dose of caffeine, your blood vessels may get hypersensitive and cause you to have a headache.
  • Taking painkillers regularly: Frequent use of pain relievers for headaches might lead to rebound headaches.
  • Hormonal shifts in females: Women tend to suffer from migraines more often throughout their menstrual cycles. Migraines are sometimes brought on by the sudden reduction in estrogen that ushers in menstruation. Birth control medications and HRT may also cause hormonal shifts.
  • Light: Light from sources such as the television, computer screen, sunlight, and fluorescent bulbs may set you off.

How Cannabis Works for Migraine Relief

Cannabis has gained attention for its potential in migraine relief due to its interaction with the endocannabinoid system. When consumed, cannabinoids like THC and CBD bind to receptors in the brain and peripheral nervous system, influencing pain pathways and inflammation. Research suggests that cannabis for migraine could alleviate symptoms by reducing the intensity and frequency of headaches. Additionally, cannabinoids may modulate serotonin levels, which play a crucial role in regulating mood and pain perception, further enhancing their therapeutic potential for migraine sufferers.

The effectiveness of cannabis for migraine relief varies among individuals, with some reporting a significant reduction in symptoms after consumption. This relief is attributed to cannabinoids’ ability to target multiple aspects of migraine pathophysiology, including vasodilation and neuroinflammation. Moreover, cannabis-derived compounds exhibit analgesic properties that can mitigate the debilitating pain associated with migraines, providing a promising alternative for those seeking non-conventional treatments.

Despite promising anecdotal evidence, more clinical trials are needed to fully understand the long-term effects and optimal dosing strategies of cannabis for migraine management. Healthcare providers emphasize the importance of personalized treatment plans and caution against self-medication due to potential side effects and legal considerations surrounding cannabis use. As research progresses, cannabis may emerge as a viable option for individuals seeking effective relief from the often debilitating symptoms of migraines.

Dr. Cecilia Rosales, a member of the research team and associate dean at the University of Arizona’s School of Public Health, stated that the study aimed to determine the efficacy and safety of Medical Marijuana for migraine.

Rosales and her colleagues looked at 12 previous studies with roughly 2,000 individuals in the United States and Italy who were 18 or older.

After reviewing the available literature, the researchers concluded that medicinal cannabis was around 60% more effective than non-cannabis therapies in attaining migraine relief. In addition, migraine days and monthly migraine frequency decreased in persons who took medicinal cannabis.

Dr. Sherry Yafai, an expert in emergency care and cannabis who works at Providence Saint John’s Health Clinic in California, is pleased with the growing evidence supporting cannabis’ therapeutic potential.

She told MNT, “Just as in this review research, we’re finding a very similar reaction in patients we’re treating as well,” in that patients’ migraine headaches last less long. “Their days-to-weeks-long headaches, based on when they treat with cannabis usage, endure just hours.”

Understanding Migraines and Current Treatments

Understanding migraines involves recognizing them as complex neurological disorders characterized by severe headaches, often accompanied by symptoms like nausea and sensitivity to light and sound. These episodes can significantly impair millions worldwide’s daily functioning and quality of life. Current treatments typically include medications to manage symptoms and prevent migraines, ranging from pain relievers to preventive drugs that target underlying causes.
