Multiple Sclerosis

Multiple sclerosis (MS) is a chronic, immune-mediated neurological disorder affecting the central nervous system (CNS), which includes the brain and spinal cord. MS occurs when the immune system mistakenly attacks the protective covering of nerve fibers called myelin, causing inflammation and damage. This damage disrupts the normal flow of electrical impulses along the nerves, leading to a wide range of symptoms that vary among individuals. Common symptoms include fatigue, muscle weakness, vision problems, and difficulties with balance and coordination. The cause of MS remains unknown, but it is believed to involve a combination of genetic, environmental, and lifestyle factors. There is currently no cure for MS, but various treatments can help manage symptoms, slow disease progression, and improve patients’ quality of life.

What is Multiple Sclerosis?

Multiple sclerosis (MS) is a chronic neurological disorder affecting the central nervous system, specifically the brain and spinal cord. It occurs when the immune system mistakenly attacks the protective covering of nerve fibers called myelin, leading to inflammation and damage that disrupts the normal flow of electrical impulses along nerves.


Symptoms of multiple sclerosis can vary widely among individuals and may include:

  1. Fatigue
  2. Muscle weakness or stiffness
  3. Vision problems, such as blurred vision or optic neuritis
  4. Difficulties with balance and coordination
  5. Numbness or tingling in the limbs
  6. Cognitive issues, including memory problems and difficulty concentrating
  7. Bladder or bowel dysfunction
  8. Emotional changes, such as depression or mood swings
  9. Pain, especially in the limbs or face


The exact cause of MS remains unknown, but it is believed to involve a combination of genetic, environmental, and lifestyle factors. Some potential contributors include:

  1. Genetic predisposition: Individuals with a family history of MS may have an increased risk of developing the condition.
  2. Environmental factors: Exposure to certain viral infections, such as the Epstein-Barr virus, may increase the risk of MS.
  3. Vitamin D deficiency: Low levels of vitamin D have been associated with an increased risk of MS.
  4. Smoking: Tobacco use may increase the likelihood of developing MS and contribute to more severe symptoms.


There is currently no known way to prevent multiple sclerosis, as the precise cause remains unclear. However, maintaining a healthy lifestyle may help reduce the risk of developing MS or minimize its impact on those already diagnosed. This includes regular physical activity, a balanced diet rich in fruits, vegetables, and whole grains, getting adequate vitamin D through sun exposure or supplements, and avoiding smoking. Early diagnosis and intervention with appropriate treatments can help slow the progression of the disease and improve patients’ quality of life through symptom management and supportive care.

Medical Marijuana as a Treatment for Multiple Sclerosis

Medical marijuana has shown potential in helping manage various symptoms associated with multiple sclerosis (MS) and improving the quality of life for some individuals.

How does medical marijuana help?

Medical marijuana may aid in managing MS through the following mechanisms:

  1. Pain relief: Certain cannabinoids have analgesic properties that can help alleviate pain associated with MS, including neuropathic pain and muscle spasms.
  2. Muscle relaxation: Medical marijuana may help reduce muscle stiffness or spasticity experienced by individuals with MS.
  3. Anti-inflammatory properties: Medical marijuana has demonstrated anti-inflammatory effects, which may help reduce inflammation and potentially slow disease progression.
  4. Improved sleep: Medical marijuana may aid in promoting better sleep quality for those experiencing insomnia or disrupted sleep due to MS symptoms.

Cannabinoids and Terpenes for Multiple Sclerosis

Certain cannabinoids may be effective in addressing symptoms associated with MS:

  1. CBD (cannabidiol): CBD has demonstrated potential benefits in reducing inflammation, providing pain relief, and alleviating muscle spasms without causing psychoactive effects.
  2. THC (tetrahydrocannabinol): THC can provide pain relief and muscle relaxation, but it is essential to use low doses to avoid unwanted side effects, such as increased anxiety or cognitive impairment.

Some terpenes may also play a role in relieving MS symptoms:

  1. Beta-caryophyllene: This terpene has demonstrated anti-inflammatory and analgesic properties, which may contribute to symptom relief.
  2. Myrcene: Myrcene possesses both anti-inflammatory and muscle relaxant properties that could potentially aid in managing MS symptoms.

It is essential to consult with a healthcare professional experienced in cannabinoid medicine when considering medical marijuana as a treatment for managing MS-related symptoms. They can help determine the appropriate strains, ratios of cannabinoids, and dosages tailored to an individual’s specific needs and circumstances. Further research is needed to fully understand the long-term effects and efficacy of medical marijuana in managing MS symptoms and side effects. It is also important to note that medical marijuana should not be considered a substitute for conventional treatments prescribed by a healthcare provider.

Dosage and Consumption Methods

Recommended dosage:

Figuring out the right dose of medical marijuana can be hard because people’s reactions to cannabinoids and terpenes can be very different. Factors such as the specific condition being treated, the patient’s weight, metabolism, and prior experience with cannabis all play a role in determining the right dosage.
Most of the time, it is best to start with a low dose and slowly increase it until you get the effects you want while minimising any possible side effects. For patients who are new to medical marijuana, starting with 2.5–5 mg of THC or CBD and slowly titrating upwards is often advised.

However, consulting a healthcare professional experienced in medical marijuana is essential to developing a personalised dosing plan tailored to the patient’s needs.

Consumption methods:

There are several methods of consuming medical marijuana, each with its advantages and disadvantages. Some common consumption methods include:

  1. Inhalation (smoking or vaping): Inhalation provides rapid onset of effects, usually within minutes, making it suitable for patients requiring immediate relief. However, smoking may pose respiratory risks, while vaping has been associated with lung injuries in some cases.
  2. Oral ingestion (edibles, capsules, tinctures): Ingesting medical marijuana provides longer-lasting effects compared to inhalation but has a slower onset, typically taking 30 minutes to 2 hours for effects to be felt. This method is suitable for patients requiring sustained relief but may require careful dosing to avoid overconsumption.
  3. Topical application (creams, balms, patches): Topicals can provide localised relief for conditions such as arthritis or skin disorders without producing psychoactive effects. The onset of action and duration of effects can vary depending on the product formulation and individual absorption rates.
  4. Sublingual administration (tinctures, dissolvable strips): Sublingual products are absorbed through the mucous membranes under the tongue, providing rapid onset of effects without the need for inhalation or ingestion. This method offers discreet consumption and precise dosing.

Obtaining a Medical Marijuana Card

Why get a medical marijuana card?

Getting a medical marijuana card is helpful for patients who are looking for other ways to treat their conditions.

  1. Legal protection: A medical marijuana card allows patients to possess, use, and in some cases, cultivate cannabis for medical purposes, within their state’s legal limits.
  2. Access to quality products: Medical marijuana dispensaries offer a wide range of tested and regulated cannabis products, ensuring patients receive safe and effective medication.
  3. Tax savings: In some states, medical marijuana patients are exempt from certain taxes applied to recreational cannabis sales.
  4. Professional guidance: Medical marijuana cardholders have access to healthcare professionals who can provide personalised recommendations, dosing advice, and ongoing support.

How to apply:

The process of obtaining a medical marijuana card varies by state but generally involves the following steps:

  1. Consult with Medical marijuana physicians to determine if medical marijuana is appropriate for your condition and obtain a written recommendation.
  2. Complete an application with the required documentation, including proof of residency, identification, and the healthcare professional’s recommendation.
  3. Submit the application to the appropriate state agency, along with any required fees.
  4. Await approval and issuance of the medical marijuana card.

Risks and Side Effects

Potential risks:

While medical marijuana can offer relief and improve the quality of life for many patients, it also carries certain risks and side effects. Some potential risks associated with medical marijuana use include:

  1. Dependency and addiction: Although the risk of addiction is considered lower than that of opioids or alcohol, some individuals may develop a dependency on cannabis.
  2. Impaired cognitive function: THC, the primary psychoactive compound in cannabis, can impair memory, attention, and reaction times, particularly with prolonged or heavy use.
  3. Respiratory issues: Smoking cannabis can cause respiratory problems, including bronchitis and lung irritation. Vaping has also been linked to lung injuries in some cases.
  4. Mental health concerns: High doses of THC or predisposition to mental health disorders can lead to increased anxiety, paranoia, or exacerbate existing mental health conditions.
  5. Drug interactions: Medical marijuana may interact with other medications, either enhancing or diminishing their effects. It is essential to discuss potential drug interactions with a healthcare professional before starting medical marijuana therapy.


Medical marijuana might not be right for every patient, especially those who already have certain health problems or risk factors. Contraindications to medical marijuana use may include:

  1. Personal or family history of substance abuse or addiction
  2. Severe liver or kidney disease
  3. Severe cardiovascular disease
  4. Pregnancy or breastfeeding
  5. History of psychosis or other severe mental health disorders
  6. Allergies or hypersensitivity to cannabis or its components

Legal Status

Where is it legal?

In the United States, the laws about medical marijuana are always changing. Currently, over 30 states and the District of Columbia allow its use under certain conditions. Each state has its own rules and a list of medical conditions that are allowed to use medical marijuana.

Even though some states have made medical marijuana legal, it is still illegal at the federal level because it is a Schedule I substance under the Controlled Substances Act.

This difference between state and federal laws can make it harder for medical marijuana patients to get jobs, find housing, or travel across state lines, among other things. Patients should research their state’s guidelines and remain aware of potential legal risks.


Medical marijuana could help relieve symptoms and improve the quality of life for many people with long-term or debilitating illnesses.

When thinking about this treatment option, it’s important to know the right dose, how to use it, how to get a medical marijuana card, possible risks, side effects, and legal status.

Work closely with a doctor or nurse who knows a lot about medical marijuana to find out if it is a good and safe choice for your needs.
