Does Medical Marijuana Help Eczema?
Introduction
Eczema, also known as atopic dermatitis, is a chronic skin condition characterized by dry, inflamed, and itchy skin. It affects millions worldwide, leading to discomfort and a diminished quality of life. Traditional treatments include topical corticosteroids, moisturizers, and immunosuppressive agents. However, these treatments don't always provide complete relief and can have side effects with long-term use. This has led researchers and patients alike to explore alternative therapies, including medical marijuana. But does medical marijuana truly help eczema?
In this post, we will walk you through the potential benefits, scientific evidence, and considerations surrounding the use of medical marijuana for eczema.
Let's dive in!
What Is Eczema?
Eczema is a multifaceted condition resulting from a combination of genetic, environmental, and immunological factors. It manifests as patches of dry, itchy, and inflamed skin, often leading to scratching that can exacerbate the condition and increase the risk of infections. The chronic nature of eczema means that individuals may experience periodic flare-ups throughout their lives.

Types of Eczema
Contrary to popular belief, eczema isn’t just a single skin condition—it’s actually an umbrella term for a group of related disorders. These conditions share common symptoms, such as red, inflamed, itchy, and irritated skin, often leading to dry, scaly patches. There are seven primary types of eczema, each with distinct causes, triggers, and appearances.
Let’s break them down:
1. Atopic Dermatitis (AD)
Atopic dermatitis is the most prevalent and well-known form of eczema. It’s an inflammatory skin condition primarily caused by an overactive immune response, which weakens the skin's protective barrier. This results in dry, cracked, itchy, and rash-prone skin. Sometimes, the skin may ooze, bleed, or become severely irritated.
Genetics play a significant role—those with a family history of asthma or hay fever are more susceptible to developing AD. In fact, research suggests a mutation in the filaggrin gene (responsible for creating a key skin protein) compromises the skin barrier, allowing moisture loss and increased vulnerability to irritants and allergens.
Atopic dermatitis often begins in infancy, typically within the first six months of life. Some individuals outgrow the condition, while others continue to experience symptoms into adulthood.
2. Contact Dermatitis
Unlike atopic dermatitis, contact dermatitis occurs when the skin reacts to direct contact with an irritating substance or allergen. It’s not hereditary and isn’t connected to other conditions like asthma.
There are two main subtypes:
Allergic Contact Dermatitis: This develops as an allergic reaction after the skin encounters a specific allergen—such as poison ivy, fragrances, or metals like nickel. Symptoms usually appear one to two days after exposure.
Irritant Contact Dermatitis: More common, this results from repeated exposure to harsh chemicals, detergents, soaps, or solvents that physically damage the skin barrier. Overwashing and frequent hand sanitizer use are common triggers.
3. Dyshidrotic Eczema
Also referred to as pompholyx, dyshidrotic eczema is distinguished by small, fluid-filled blisters primarily on the palms, soles, and sides of fingers and toes. These blisters are often intensely itchy and may cause redness and flaking.
While the exact cause is unclear, dyshidrotic eczema is believed to have genetic links and is more common in people with other types of eczema. Stress, sweating, exposure to metals (like nickel), and seasonal allergies can all contribute to flare-ups. Interestingly, it tends to affect women more frequently than men.
4. Neurodermatitis
Neurodermatitis, also known as lichen simplex chronicus, typically appears as one or two localized, thickened, and leathery patches of skin due to continuous scratching. This chronic itch-scratch cycle is often triggered by stress, anxiety, or other emotional factors, and can worsen over time.
This condition affects approximately 12% of the population, particularly women aged 30 to 50 who have a history of atopic dermatitis or contact dermatitis. Persistent scratching may lead to bleeding, infections, or long-term scarring.
5. Nummular Eczema
Nummular eczema, or discoid dermatitis, is characterized by round, coin-shaped patches of irritated, inflamed, and sometimes oozy skin. These spots can be itchy and are often mistaken for psoriasis due to their similar appearance.
This form of eczema is more prevalent in men and can be triggered by dry skin, insect bites, minor skin injuries, or allergic reactions to metals and chemicals. Environmental factors such as cold, dry weather may also play a role in flare-ups.
6. Seborrheic Dermatitis
Seborrheic dermatitis is a chronic form of eczema that primarily affects oil-rich areas of the skin, like the scalp, face (especially around the nose), and upper back. In infants, it’s commonly known as cradle cap.
The condition is associated with an inflammatory response to an overgrowth of Malassezia yeast, which naturally exists on the skin. It presents as greasy, yellowish scales, redness, and itching.
Adults aged 30 to 60 are most affected, and several factors can exacerbate symptoms, including hormonal changes, stress, cold weather, and underlying health conditions such as Parkinson’s disease, HIV, or depression.
7. Stasis Dermatitis
Also known as venous eczema or gravitational dermatitis, stasis dermatitis occurs when poor circulation, particularly in the lower legs, leads to fluid buildup and skin inflammation. It’s commonly seen in older adults with weakened leg veins, a condition known as venous insufficiency.
Symptoms include swelling, redness (or brownish/grey discoloration in darker skin tones), aching, and itchy skin, often accompanied by scaly patches or ulcers. Chronic stasis dermatitis can be a sign of underlying cardiovascular or kidney disease and should be managed carefully.
The Endocannabinoid System and Skin Health
To comprehend how medical marijuana might influence eczema, it's essential to understand the endocannabinoid system (ECS). The ECS is a complex cell-signaling system present throughout the human body, including the skin. It plays a pivotal role in regulating various physiological processes such as pain, mood, appetite, and immune response.
In the skin, the ECS helps regulate functions like cell growth, differentiation, and immune competence. Disruptions or imbalances in the ECS have been linked to various skin disorders, including eczema. Cannabinoid receptors (CB1 and CB2) in the skin can interact with endocannabinoids (naturally produced by the body) and phytocannabinoids (like THC and CBD from cannabis), influencing skin health and disease outcomes.
Scientific Evidence on Cannabinoids and Eczema
Several studies have explored the potential of cannabinoids in treating eczema and related skin conditions:
Topical Cannabinoids: A comprehensive review highlighted the effectiveness of topical cannabinoids, such as CBD and palmitoylethanolamide (PEA), in treating various dermatologic conditions, including atopic dermatitis. For instance, a study involving 60 female participants with asteatotic eczema showed significant improvements in scaling, dryness, and itchiness after using topical PEA and anandamide (AEA)
PEA Creams: A 2008 study involving 2,456 patients demonstrated that creams containing PEA significantly improved eczema symptoms. Participants reported reduced dryness, scaling, redness, and itching. Notably, 56% of the participants were able to discontinue the use of steroid creams
CBD Ointments: A 2019 study assessed the effects of a CBD-infused ointment on 20 individuals with psoriasis, eczema, and resulting scars. After three months of daily application, participants experienced improvements in skin elasticity, hydration, and a reduction in psoriasis symptoms and scarring
Chronic Itch Relief: A case study by Johns Hopkins Medicine reported that medical marijuana provided rapid relief from chronic itch in a patient unresponsive to traditional therapies. The patient experienced a significant reduction in itch intensity shortly after using medical marijuana.
Mechanisms of Action
The potential benefits of cannabinoids in treating eczema can be attributed to several mechanisms:
Anti-Inflammatory Properties: Cannabinoids like CBD have been shown to inhibit the production of pro-inflammatory cytokines, reducing inflammation in the skin
Regulation of Skin Cell Proliferation: The ECS plays a role in controlling the growth and differentiation of skin cells. Cannabinoids can modulate keratinocyte proliferation, which is often dysregulated in eczema
Itch Relief: Activation of cannabinoid receptors has been linked to reduced sensations of itchiness. This is particularly relevant for eczema patients, for whom itching is a predominant symptom.
Considerations and Potential Side Effects
While the preliminary findings are promising, several considerations should be kept in mind:
Lack of Large-Scale Clinical Trials: Most studies to date have been small-scale or anecdotal. Comprehensive, large-scale, randomized controlled trials are necessary to establish the efficacy and safety of medical marijuana for eczema
Variability in Products: The concentration and purity of cannabinoid products can vary widely. This variability can influence their effectiveness and the likelihood of side effects.
Potential Side Effects: While topical applications of cannabinoids are generally considered safe, some individuals may experience mild side effects such as skin irritation. Systemic use of medical marijuana can have psychoactive effects, which may not be desirable for all patients.
Conclusion: Can Medical Marijuana Help Eczema?
Emerging research suggests that medical marijuana—especially cannabinoid-infused topicals like CBD and PEA—may offer meaningful relief for eczema sufferers. By interacting with the body's endocannabinoid system, cannabinoids show promise in reducing inflammation, relieving chronic itching, and improving skin hydration and elasticity. While more large-scale clinical studies are needed to fully validate these benefits, current evidence indicates that medical marijuana could be a powerful, natural addition to eczema treatment plans.
