Chemotherapy is a widely used treatment method in the battle against cancer, employing powerful drugs to destroy rapidly dividing cancer cells or inhibit their growth. Developed over several decades, chemotherapy has become an essential component of cancer treatment plans, often used in conjunction with other therapies like surgery and radiation. While effective in targeting cancer cells, chemotherapy may also affect healthy cells that divide rapidly, leading to potential side effects such as hair loss, nausea, and fatigue. The precise combination and dosage of chemotherapy drugs are tailored to individual patients, aiming to maximise effectiveness while minimising adverse reactions. Timely administration and proper management of side effects are crucial aspects of successful chemotherapy treatment.

What is Chemotherapy 

Chemotherapy refers to the use of drugs to treat cancer by targeting rapidly dividing cells, including cancer cells. It is essential to note that chemotherapy itself is not a disease or condition but a form of treatment. Therefore, discussing symptoms and causes in the context of chemotherapy may be misleading. Instead, we can discuss side effects, indications for its use, and measures to alleviate side effects.

Side Effects of Chemotherapy

Since chemotherapy targets rapidly dividing cells, it may also affect healthy cells that divide quickly, leading to various side effects:

• Hair loss
• Nausea and vomiting
• Fatigue
• Mouth sores
• Diarrhoea or constipation
• Anaemia
• Increased risk of infections due to lowered white blood cell count
• Bleeding and bruising easily due to reduced platelet count

These side effects usually subside after completing chemotherapy treatment.

Indications for Chemotherapy

Chemotherapy is used in various situations to treat cancer:

1. Curative intent: In some cases, chemotherapy is administered to eliminate all cancer cells and cure the patient.
2. Adjuvant therapy: After surgery or radiation therapy, chemotherapy may be given to reduce the risk of cancer recurrence.
3. Neoadjuvant therapy: Chemotherapy can be used before surgery or radiation therapy to shrink tumours, making them easier to remove or treat.
4. Palliative care: In advanced cancer stages, chemotherapy aims to alleviate pain and improve the patient’s quality of life by controlling cancer growth and spread.

Measures to Alleviate Side Effects

While it is challenging to prevent chemotherapy side effects entirely, certain measures can help manage and alleviate them:

1. Medication: Drugs like anti-nausea medications and pain relievers can help manage specific side effects.
2. Dietary changes: Eating smaller meals, staying hydrated, and avoiding triggering foods can help manage nausea and other gastrointestinal side effects.
3. Oral hygiene: Regular dental check-ups and maintaining good oral hygiene can help prevent mouth sores.
4. Infection prevention: Practising good hygiene, avoiding crowded places, and staying up-to-date with vaccinations can help reduce the risk of infections during treatment.

It is crucial to communicate with your healthcare team about any side effects you experience during chemotherapy, as they can provide guidance and support in managing them effectively.

Medical Marijuana as a Treatment for Chemotherapy Side Effects

Medical marijuana, or medical cannabis, refers to the use of the Cannabis plant and its components (cannabinoids) to treat various medical conditions or alleviate symptoms, including those resulting from chemotherapy.

How does medical marijuana help with chemotherapy side effects?

Medical marijuana has shown promise in alleviating some common side effects of chemotherapy:

1. Nausea and vomiting: Medical cannabis, particularly THC, has been found to help reduce chemotherapy-induced nausea and vomiting.
2. Pain management: Both THC and CBD have analgesic properties that may help manage cancer-related pain and neuropathy caused by chemotherapy.
3. Appetite stimulation: Medical marijuana can help improve appetite in cancer patients undergoing chemotherapy, promoting proper nutrition and weight maintenance.
4. Anxiety and depression: Medical cannabis may help alleviate anxiety and depression experienced by cancer patients during their treatment.

Cannabinoids and Terpenes for Chemotherapy Side Effects

In addition to the major cannabinoids like THC and CBD, there are other minor cannabinoids and terpenes found in cannabis plants that may have potential benefits for managing chemotherapy side effects.

Which cannabinoids and terpenes are most effective for chemotherapy side effects?

1. Tetrahydrocannabinol (THC): THC is a psychoactive compound known for its pain-relieving, appetite-stimulating, and antiemetic properties, making it effective in managing several chemotherapy side effects.
2. Cannabidiol (CBD): CBD is a non-psychoactive cannabinoid with demonstrated analgesic, anti-inflammatory, and anxiolytic properties that can help alleviate pain and anxiety related to chemotherapy.
3. Beta-caryophyllene: This terpene acts on the same receptors as CBD, offering potential anti-inflammatory and analgesic benefits for chemotherapy patients.
4. Limonene: Limonene is a terpene with potential anxiolytic and antidepressant effects, which may help improve mood and reduce anxiety during chemotherapy treatment.

It’s important to note that research on specific cannabinoids and terpenes for chemotherapy side effects is still limited, and more studies are needed to determine their safety and efficacy. If you are considering using medical marijuana to manage chemotherapy side effects, it is essential to consult with a healthcare professional who is knowledgeable about medical cannabis. They can help you determine the most appropriate treatment plan and monitor your progress to ensure the safe and effective use of medical marijuana for your specific needs.

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 minimizing 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 personalized 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 localized 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.
