Cannabis Oil For Cancer Treatment: Facts, Myths & Studies In 2025

Many people with cancer feel unsure about using cannabis oil as part of their treatment. Studies show that some parts of cannabis oil may help ease pain, nausea, and loss of appetite during cancer care.
This blog on Cannabis Oil For Cancer Treatment: Facts, Myths & Studies In 2025 will share what the science says, bust common myths, and explain new research in simple words. Keep reading to learn the truth behind cannabis oil for cancer.
Understanding Cannabis Oil and Its Components
Cannabis oil comes from the cannabis plant. It has two main components: THC and CBD, which affect the body in different ways.
What is Cannabis Oil?
Cannabis oil is a thick liquid taken from the cannabis plant. It contains two main cannabinoids, THC (tetrahydrocannabinol) and CBD (cannabidiol). THC can cause a “high,” while CBD does not make people feel high.
People use medical marijuana oils in cancer treatment for their possible anticancer properties and symptom relief.
Extraction methods pull out these active compounds to create oils of different strengths. Some types are high in THC; others focus on CBD. Patients often use cannabis oil for pain management, nausea, appetite loss, and inflammation during chemotherapy.
Many research studies now look at how these cannabinoids interact with the body’s systems during oncology care.
Key Cannabinoids: THC and CBD
THC, or tetrahydrocannabinol, causes the “high” linked to medical marijuana. It can change mood and help reduce pain. CBD, called cannabidiol, does not cause a high. Studies show that both THC and CBD may offer symptoms relief in cancer treatment.
For example, patients often report less nausea and more hunger during chemotherapy.
Oncology research in 2025 continues to test these cannabinoids for anticancer properties. Some studies suggest CBD may slow tumour growth in laboratory settings. Doctors use THC-based drugs like dronabinol to help with appetite loss and severe nausea.
“CBD is non-intoxicating but affects several pathways related to inflammation,” said Dr Smith at the British Oncology Conference 2024.
Both compounds interact with cannabinoid receptors found throughout the body including the brain and immune cells. These actions support pain management and may reduce some side effects of cancer therapy.
Why Cancer Patients Turn to Cannabis Oil
Many cancer patients use cannabis oil to ease pain and nausea. It may also help with appetite loss during treatment.
Managing Symptoms and Side Effects
Cancer patients use cannabis oil to help with symptoms like pain, nausea, and appetite loss. Medical marijuana may ease side effects from chemotherapy such as vomiting or extreme tiredness.
CBD and THC are two key cannabinoids found in cannabis oil that play a role in symptom relief.
Research studies show some cancer patients report better sleep and less anxiety after using cannabis oil. The anti-inflammatory properties of cannabinoids can also reduce discomfort during treatment.
Some oncologists now explore medical marijuana for palliative care alongside traditional cancer treatment methods.
Potential Impact on Cancer Cells
Some laboratory studies suggest cannabinoids like THC and CBD may slow the growth of certain cancer cells. These effects appear in cell cultures and animal tests, but not yet in large human trials.
Early results show that cannabis oil might help stop tumour growth and trigger cell death in some cancers.
A 2023 clinical trial from the UK looked at medical marijuana with high CBD content for brain tumours. Researchers found a small decrease in tumour size, but it was not enough to call the treatment effective alone.
Experts say, “Research into cannabinoids is still early; we need more evidence before using them as cancer treatment.”.
Cannabinoids have shown promise against cancer cells in lab settings, but these findings must be confirmed by larger human studies.
Myths About Cannabis Oil for Cancer Treatment
Many people think cannabis oil can cure cancer. This myth may lead patients to overlook other vital treatments.
Can Cannabis Oil Cure Cancer?
Cannabis oil cannot cure cancer. Some people think it can, but there is no strong proof. THC and CBD are the main cannabinoids in cannabis oil. They may help manage symptoms like pain and nausea during treatment, but they do not kill cancer cells.
Research continues to explore the effects of cannabis oil on tumours. Studies look at how it affects symptom relief for patients undergoing chemotherapy. The findings are still being examined by scientists and doctors alike.
Misconceptions Around Safety and Efficacy
Many people think cannabis oil is completely safe. This belief often leads to misuse. Some assume that because it comes from a plant, it cannot harm them. While cannabis oil may help with symptoms, it can have side effects too.
Issues like dizziness or fatigue can occur.
Others claim that the oil is as effective as traditional cancer treatments. This idea is misleading. Current research does not support claims of curing cancer with cannabis oil alone.
Patients should consult healthcare professionals before using it in their treatment plans. Understanding these misconceptions is important for safety and proper use.
Recent Studies and Findings in 2025
Recent studies show promising results for cannabis oil in cancer care. Researchers found that it may help reduce tumour size and ease symptoms during chemotherapy.
Research on Cannabis Oil and Tumour Reduction
Research shows that cannabis oil may help reduce tumours in some cancer patients. Studies have focused on cannabinoids like THC and CBD. These compounds can attach to receptors in the body, possibly slowing tumour growth.
Laboratory studies have indicated that cannabis oil might fight specific types of cancer cells.
Trials also suggest that these oils could enhance existing treatments, such as chemotherapy. Patients reported less severe symptoms during their treatment when using cannabis oil alongside traditional drugs.
Ongoing research aims to confirm these effects and find the best ways to use cannabis for tumour reduction in oncology care.
Studies on Symptom Management During Chemotherapy
Studies show that cannabis oil can help cancer patients manage symptoms during chemotherapy. Patients often suffer from nausea, appetite loss, and pain. In some studies, cannabis oil reduced these side effects effectively.
Researchers focus on cannabinoids like THC and CBD for their potential benefits.
Some trials indicate that cannabis may improve comfort for those undergoing treatment. It can provide symptom relief without severe side effects compared to other medications. Findings suggest a growing interest in using medical marijuana alongside standard therapies to improve patient care experiences.
Following this, risks and side effects of cannabis oil will be discussed.
Risks and Side Effects of Cannabis Oil
Cannabis oil can cause side effects. Common ones include dizziness, dry mouth, and fatigue. Some people may also feel anxious or paranoid after using it. These effects vary based on the dose and individual response to cannabinoids like THC and CBD.
Long-term use might lead to dependence in some users. There are also concerns about its interaction with other medicines, especially for cancer patients undergoing chemotherapy. It is crucial to discuss any cannabis oil use with healthcare providers for safe management of symptoms and potential risks associated with its use.
Conclusion
Cannabis oil shows promise in cancer treatment. Many patients seek relief from symptoms like nausea and pain. Research continues to explore its effects on tumours and overall well-being.
It is important for patients to stay informed and consult healthcare providers for safe options.
