Cannabis-Related Headache Origins

Cannabis-Related Headache Origins

September 12, 2023

Cannabis, a substance known for its multifaceted effects on users, remains a subject of intrigue when it comes to its impact on headaches. 

The peculiar nature of cannabis is that it appears to evoke a wide spectrum of responses in those who consume it. Contrasting reports have emerged, with some individuals asserting that cannabis serves as a reliable pain-reliever for their headaches, while others adamantly contend that it exacerbates their discomfort. 

The world is rife with personal stories attributing cannabis as the catalyst behind pounding head pain, yet an equally fervent group of individuals suffering from chronic headaches and migraines ardently advocate for cannabis as a means to mitigate the intensity and frequency of their afflictions.

In the realm of medicinal and scientific inquiry, it is imperative to transcend the confines of individual experiences and delve into the corpus of scholarly research. By doing so, we can gain a more comprehensive understanding of the intricate dynamics at play when cannabis interacts with headaches and the human physiology at large.

Exploring Cannabis as a Potential Headache Remedy

In recent years, a growing body of evidence has shed light on the potential of cannabis as a viable option for alleviating headaches. Traditional painkillers often fall short in providing effective relief for headache sufferers and, in some instances, may even contribute to the development of medication overuse headaches.

A study conducted in July 2020, featured in the Journal of Integrative Medicine, delved into the therapeutic effects of dried cannabis flower on headache and migraine pain. Over a span of three years, from 2016 to 2019, 699 participants participated in the study, offering insights into the severity of their symptoms and the specific strains of dried cannabis flower they used to manage their pain. Researchers gauged changes in pain intensity using a scale ranging from 0 to 10, both before and after cannabis consumption.

The findings were striking, with a remarkable 94% of participants reporting symptom relief within two hours of cannabis consumption. On average, participants experienced a reduction of 3.3 points on the ten-point pain scale. Interestingly, male users appeared to derive more significant relief than their female counterparts, and younger users also experienced more pronounced benefits. Cannabis varieties boasting THC levels of 10% or higher seemed to offer more effective relief for headache sufferers.

Another study, published in the Journal of Pain in June 2020, delved into the impact of cannabis on headaches and migraines. This research harnessed data from Strainprint, a medical cannabis application that enables patients to monitor their symptoms before and after cannabis usage. The study scrutinized data from 12,293 sessions where cannabis was used to alleviate headaches and 7,441 sessions targeting migraines.

The results indicated that cannabis effectively reduced symptoms in 89.9% of headache cases and 88.1% of migraines. Parallel to the findings in the Journal of Integrative Medicine, men were marginally more likely to experience relief compared to women (90.9% vs. 89.1%). The data revealed an impressive 47.3% decrease in headache severity and a 49.6% decrease in migraine intensity. Intriguingly, the study suggested that the efficacy of cannabis for headache relief remained consistent across different cannabis strains and cannabinoid concentrations. Moreover, the research did not uncover any apparent link between cannabis use and the development of medication overuse headaches, a concern associated with conventional treatments.


Exploring the Complex Relationship Between Cannabis and Headaches

While there is evidence suggesting the potential benefits of cannabis in managing headaches, the picture becomes more nuanced when considering its role in triggering or worsening these debilitating conditions. A study published in the Journal of Pain in 2020 found that cannabis exacerbated headache symptoms in 2.4% of headache cases and 3.1% of migraine cases, adding a layer of complexity to the discussion.

Another study from 2017, featured in the Harm Reduction Journal, highlighted that cannabis can indeed lead to the exacerbation of headache symptoms or even trigger new episodes. Researchers postulated that variables such as the timing of cannabis use, its frequency, the method of administration, and dosage could all play a pivotal role in determining whether cannabis helps or hinders headache sufferers. Additionally, the study pointed out that certain cannabinoids and terpenes within cannabis may have a pain-relieving effect, while others could potentially exert contrasting influences.

It's worth noting that headaches have also been linked to what colloquially is referred to as a "weed hangover." Following excessive cannabis consumption, individuals sometimes report experiencing symptoms such as brain fog, grogginess, and headaches on the day after use.

Furthermore, withdrawal symptoms after chronic cannabis use can also provoke headaches. A study involving 469 frequent cannabis smokers, published in Drug and Alcohol Dependence in 2010, revealed that 23.2% of participants experienced headaches as a consequence of cannabis withdrawal.

The Aftermath of Cannabis: Hangovers

Following the use of cannabis or alcohol, individuals may occasionally wake up the next day with what is commonly referred to as a "weed hangover." Among the symptoms of a weed hangover, headaches are a possible unwelcome companion. Similar to the way alcohol-induced headaches may arise from dehydration, weed hangover headaches can often be mitigated by rehydration through ample water consumption.

Withdrawal Symptoms from Cannabis

Abruptly discontinuing the use of cannabis, particularly after a period of heavy or prolonged consumption, can lead to a mild form of withdrawal known as cannabis withdrawal syndrome. Among its various withdrawal symptoms, headaches or migraines can manifest. Research has indicated that around 23% of individuals undergoing cannabis withdrawal experience headaches

These withdrawal-related headaches typically peak in intensity within the first week of ceasing cannabis use and tend to subside in severity within 10 to 20 days post-abstinence. Notably, discontinuing cannabis use may also lead to rebound headaches, known as "medication overuse headaches," in individuals who previously relied on cannabis as a remedy for their headaches or migraines.

Cannabis Varieties Linked to Headaches

Over a brief period, headaches and migraines can potentially be triggered by the consumption of cannabis products with high THC content, such as concentrates and hash. The act of smoking cannabis may also induce coughing, and the inhalation of ash particles combined with coughing can act as headache triggers. Furthermore, smoking and vaping may exacerbate sinus headaches in some individuals.

Although less common, the use of CBD products can also, in rare instances, result in headaches.

Distinguishing Weed Hangovers from Alcohol Hangovers

A weed hangover often presents with the following symptoms upon awakening:

1. Brain fog

2. Grogginess

3. Reduced alertness

4. Headaches

5. Dry eyes

6. Dry mouth

7. Fatigue

8. Nausea

9. Impaired memory

Comparatively, alcohol hangovers share some symptoms with weed hangovers, such as headaches, dehydration, poor memory, difficulty concentrating, anxiety, and lightheadedness. However, alcohol hangovers tend to be more severe and may include severe nausea and vomiting.

Importantly, weed hangovers are generally milder and less detrimental to the body than alcohol-induced hangovers. Unlike alcohol, cannabis does not possess the same toxic properties.

Assessing the Symptoms

The nature of a cannabis-induced headache can vary depending on the specific type of headache experienced. Furthermore, if the headache stems from a hangover or withdrawal caused by cannabis, other associated symptoms may coexist.

Cluster Headaches: Some individuals may find that cannabis triggers cluster headaches, which usually affect one side of the head, particularly around the eye area.

Migraine Headaches: Cannabis use can exacerbate or precipitate migraine headaches, which may be accompanied by symptoms such as nausea, vomiting, temporary vision disturbances, heightened sensitivity to light, and visual disturbances like spots or flashes.

Sinus Headaches: Smoking or vaping cannabis can be a potential trigger for sinus headaches, characterized by pressure in the eyes, cheeks, and forehead.

Strategies for Managing Cannabis-Induced Headaches

Addressing headaches linked to cannabis use can involve a variety of approaches, as what works best may differ from one individual to another. Sometimes, a combination of the following strategies proves most effective:

1. Maintain Hydration: While cannabis itself may not directly cause dehydration, staying adequately hydrated is essential for headache prevention and relief. Drinking several glasses of water when experiencing a headache may help alleviate it.

2. Utilize Pain Relief: Over-the-counter pain medications like aspirin, paracetamol, and ibuprofen can be helpful in relieving headaches. Ensure you follow the recommended dosage and consult a healthcare professional if unsure.

3. Eat a Balanced Meal: For those waking up with a cannabis-related hangover, focusing on a nutritious breakfast comprising carbohydrates, protein, and healthy fats can be beneficial.

4. Moderate Caffeine: Caffeine can be a useful tool in headache management, but it should be consumed in moderation. Excessive caffeine intake may worsen headaches in some individuals.

5. Massage and Cold Compress: Massaging the temples and head can alleviate headache pain, and applying a cold compress to the head may also provide relief.

Preventing Cannabis-Related Headaches

Preventing cannabis-induced headaches often entails making informed choices about your cannabis consumption:

1. Opt for Less Potent Strains: Selecting strains with lower THC concentrations or using balanced THC-to-CBD cannabis products may help reduce the likelihood of experiencing headaches.

2. Alter Your Consumption Method: Opt for non-smoking methods of cannabis ingestion to avoid coughing-induced headaches associated with smoking.

3. Reduce Frequency: If cannabis use leads to headaches, consider reducing the frequency of consumption. Avoid using cannabis daily or on most days of the week.

4. Stay Hydrated: Ensure you stay adequately hydrated by drinking water before, during, and after using cannabis.

5. Avoid Mixing with Alcohol: Preventing the combination of alcohol with cannabis can help sidestep the hangover and headache that either substance can induce.

In conclusion, understanding the potential causes and management strategies for cannabis-related headaches can empower individuals to make informed choices and alleviate discomfort when needed.
